1 WHAT IS VMIX?
vMix is live video production software that can turn a regular
Windows computer into a professional video production studio. The
software allows you to mix together video and audio sources into a
production which can be recorded, streamed and connected to a
number of popular video production workflows. The output of vMix
can be set up in standard definition (SD), high definition (HD), and
even 4K. All you need is a PC desktop or laptop with Windows 10
and a DirectX10 compatible graphics card.
More specific system requirements are available at
https://www.vmix.com/software/supported-hardware.aspx.
The layout of vMix is designed to create the look and feel of a
professional broadcast studio with both preview and output windows
set side by side during operation. Some users may feel a bit
overwhelmed at first but will quickly find the interface both intuitive
and powerful.
What Are You Going to Learn in This Book?

2
In this book, you will learn everything you need to know to set up
and operate vMix like a pro. First, you will learn how to download
the software, get set up and become familiar with the interface. Next,
you will learn about your audio-visual mixing options and common
workflows associated with vMix productions. Then, you will learn
how to get all your sources connected.
vMix accepts inputs in multiple formats, including cameras, capture
devices, NDI (Network Device Integration) sources, video files, and
even more advanced input sources such as SRT and RTSP live video
streams. You will then learn about all the features within the software
you can use to mix sources and improve the look of your video.
Next, you will be introduced to options for controlling and viewing
your video production. Finally, you will see how easy it is to begin
your own production for recording or live streaming. You can even
use the virtual camera output from vMix to send audio and video
into a webinar or video conference software.
How Does vMix Compare to Other Solutions in the
Market?
There are several options for video production software, but vMix
hits the sweet spot of features and value for many users and
organizations. It has a unique pricing strategy that allows users with
different budgets and needs to choose the best option. It comes in
five editions Basic, Basic HD, HD, 4K, and Pro, ranging in price
from free to $1200.
Many of the best core features are included in even the lowest-priced
editions. The lowest-priced paid option ($60) offers HD resolution,
three camera inputs, overlays, built-in animated titles, scoreboards,
and tickers. All versions allow the user to record and send up to three
simultaneous live streams. One of the greatest features of vMix is its
ability to grow with you. New streamers can purchase a license for
what they need at the time and quickly upgrade, adding more features
without having to learn a new software environment.
For this reason, vMix is a great choice for many users because it isn’t
likely you will have to stop the learning process and switch to another

3
software because of a technical limitation. vMix is used for simple
productions and advanced solutions everyday all around the world. In
fact, if you keep an eye out, you will find the world’s top broadcast
professionals using vMix in even the most mission critical situations.

4
2 GETTING STARTED
Part of what makes vMix great is that it is available in six editions to
fit your exact needs and budget. If you are not sure what works best
for you, you can try the full edition for free for 60 days. That way,
you can see what features and options you need before you decide.
The six editions differ in the features that they unlock. With the free
edition, you get a fully functional program with four inputs, two
camera inputs, and a maximum resolution of 768 x 576 (SD). It also
includes the ability to send three simultaneous live streams and
record. You can take advantage of one video overlay channel and
access built-in animated titles, scoreboards, and tickers.
The Basic HD edition adds an additional camera input and bumps
resolution up 1080p. The next level (HD) virtually eliminates input
limits with a total of 1000 inputs for cameras or any other source. It
also adds vMix Call for one caller, which is great for bringing in
remote guests to your production. It also offers a total of four
overlay channels. The final two editions, 4K and Pro, increase the top
resolution to 4K plus add more advanced features like dual recording,
instant replay, and PTZ camera control.
Installing vMix
Whether you have already purchased a vMix license or want to try the
free 60-day trial with full functionality, the process is the same:
Go to vMix.com
1. Click on the download button near the top of the screen.
2. Click the button to begin the download.
3. Run the installer.
4. Follow the installation prompts.
5. Enter your email to begin the free trial or enter your vMix
registration key that you received after a purchase.

5
Once the software is installed and running, it will prompt you to
select a preset. Do not worry if you aren’t sure about this. You can
change it later. vMix presets are used to save layouts of inputs. These
presets can be saved and loaded as an easy way to switch and recall
projects you have worked on in the past. You will want to pick the
option that matches the resolution and frame rate of your cameras or
other video sources. If you have installed the software on an older,
lower-power computer, you may need to choose a lower resolution
and frame rate to ensure smooth operation.
Updating vMix
One of the great things about vMix as a company, is their support for
new features. The creators of vMix pay close attention to their
community of users who actively post new ideas in the user forums.
If there is enough support for a new feature idea, it is usually
implemented in the software within a period of time. As new updates
become available, you will see a little message at the bottom of vMix
that says, “Update Available.”
Each purchase of vMix includes 12 months (1 year) worth of free
updates. After one year, you will need to purchase additional updates.
You can check to see if you are eligible for free updates and purchase
additional updates by logging into your vMix account at
https://account.vmix.com/.

Finding Help
Once you are up and running, be sure to go back to vMix.com to get
all the information and support you may need to get started. Clicking
on the “support” button on the home page will give you access to the
user guide and training videos. You can also search the knowledge
base for answers to frequently asked questions and known issues, join
the forums to share knowledge with other users, and even reach out
to support if you can’t find the information you need.
Now with the software installed and access to all the help you may
need, it is time to dig in and get started with vMix.
The Interface
vMix is packed with features and options. Fortunately, you do not
need to master all of them to get started. It is best to first familiarize
yourself with the overall layout and functionality of the interface.
The Preview and Output Windows
When you open vMix for the first time, you will see a blank canvas.
This will come to life as you begin to add pieces to your production.
Taking up much of the screen, you will see two windows. The on the
right is the “output” window, and the one on the left is the “preview”

7
window. The output window shows what is currently being sent to
your live stream or recording. This is often referred to as the program
monitor. Whatever is in the output window is “live” meaning its
being recorded or live streamed depending on the enabled features.
The preview window lets you view an input source before sending it
to the output with a transition button. Using the preview window,
you can be sure that you have the right source, and everything looks
good before switching it to the output.
The Input Area
On the bottom left of vMix, is one of the most important parts of
the interface, the input area. This is where you set up everything you
want to add to your production, including cameras, videos, images,
and websites. Anything that you eventually want to end up on the
output screen needs to start here.
The Transition Bar
In the center of the screen, between the preview and output
windows, is the transition bar. This is where you can switch from
what is in the preview window to the output. There are multiple
options for this, including an instant cut. Next to each of the other
additional options is a dropdown menu where you can choose from
several additional preset transitions. There is also a manual fader bar
at the bottom that allows you to manually control the transition
speed.
Other Features
Other features of vMix will be covered in future chapters but you
should take some time to explore the interface. Check out the
Settings menu in the upper right to adjust some of the more
advanced settings. Also, look at the control button option across the
bottom bar next to Add Input. Record enables recording of the

8
output. Click on the gear icon to choose the filetype, location, and
other recording settings.
The External output feature allows you to send audio and video out
of vMix in several ways. Click on the gear to see how you can select
what sources are assigned to what outputs. Click the gear next to the
stream to set up your live stream to multiple destinations.
On the far right are several menus, including one for overlay settings,
statistics, shortcuts, and a hamburger menu that will reveal several
other submenus.
There is no need to master all of these menus and settings yet. This
chapter is to help you understand how the interface is laid out and
how to find things as you need them later. Very few operators will
ever use every possible setting or feature of vMix, but it is good to
know where they are.
Adding Inputs & Input Settings
Inputs are the foundation of your vMix production. An input is any
element that you want to add as part of your video production. They
can include cameras, videos, images, PowerPoint presentations, audio
and other sources. vMix makes it easy to add inputs and then adjust a
wide range of settings to get your input ready for your production.
Start by adding a camera. Most video productions use cameras as the
central element connecting viewers to the event and activity. Most
cameras can be connected to your computer via capture devices,
either with internal PCIe capture cards or external SDI or HDMI
capture cards via USB. Cameras can also be connected over an
ethernet network using NDI.
To get started, make sure your camera is connected and click on the
“Add Input” menu at the bottom left of the screen. When the dialog

9
box opens, you will see down the left side every type of input you can
add. You will learn in more detail how all these different sources
function. For now, click Camera.
From the dropdown menu, click on your camera or capture device. If
you are using a Magewell, Blackmagic, or AJA capture device, vMix
should be able to automatically detect your settings from the capture
device and camera. You can double check those settings in the dialog
box. You will want to be sure the camera’s frame rate matches the
master frame rate of your production. You can double check that in
the corner of your interface screen. If you would like to use the audio
from this source, click on the Audio Enabled checkbox and choose
the source from the dropdown menu. When you are done, click OK.

10
Once you have added a source, you will have access to many other
settings. Just locate the input and click on the gear icon. This will
open the settings menu for that source. You will likely want to
change the name of the source here so it will be easy to reference as
you add more sources. You can also add the source to one of the
color categories. Color categories can be used to organize your inputs
into tabs. As your production grows, you should consider naming
every input and organizing inputs into these tabs for quick reference.

11
You can create names for these tabs by right clicking the tabs and
entering titles.
Under general settings you can determine what will happen when you
click the source. You can have it move to the preview window, cut
directly to the output, or choose from transition and overlay options.
You can also choose to to check the Automatically mix audio
setting. If your individual cameras are connected to their own
microphones and you want that camera’s microphone to become
active when you switch to the camera, check this box. If you have a
master audio source from a sound board of independent mics, you
will want to be sure this box is not checked.
Down the left side of this dialog box you can explore the various
other setting options you will have for this input. You can adjust the
color, apply color correction, set position, set up chroma and luma

12
keys. You can also set multi-view options, set up action triggers,
control tally lights, and even remotely operate PTZ cameras.
Once you have added a camera, you can go ahead and add additional
sources following the same steps.
Mixing Inputs Together with MultiView
vMix's Input MultiView makes it easy to design custom layouts that
combine multiple input sources into one scene. For instance, you
could have a camera input as the main image and then add a
backdrop, an inset picture-in-picture video, a lower thirds title, etc.
The best part is that, when you create this MultiView input, all these
sources are still usable as independent sources.
Input MultiView is not the same as overlay channels. You can setup a
Multiview input combining several inputs and still have access to all
the overlay channels. Also, keep in mind that Input Multiview is not
the same as the Fullscreen MultiView output, which allows you to see
and organize views of your entire production. For example, Input
MultiView would be used to create an input with multiple layers and
a Multiview output would be used to monitor your production on a
second monitor.
Creating a MultiView Input

13
Up to ten MultiView layers can be set up on any input. A great way
to get started is to create a brand-new blank input for testing. Just
click Add Input and select the Colour option. Next, click the gear
icon in the newly added input. Under the General options, give it a
name so you can easily find it later.
Setting it Up
Now select MultiView from the options on the left side to begin
setting it up. On the right, you will see various templates for your
MultiView like side by side, picture in picture, and a three by three
grid. These templates are just a starting point to save you time and
effort. You can change the layout as you go, and even save layouts
for the future using the Add button.
On the left are the ten positions where you can add inputs to your
Multiview. The order represents the position of the layers back to
front. Input Ten is the top layer, whereas input One is the furthest
layer in the back.
Once you have selected all your inputs, there are a couple of options
for moving them around. You may be satisfied with the layout of the
template you choose. But, if not, you can click and drag to move the
elements around in the window at the bottom. Holding the shift key
while clicking and dragging will resize the input keeping the aspect

14
ratio in scale. To gain more control, you can click the Position
button next to each layer and use the sliders to adjust the layers
position.
Saving Templates
Once you have a layout you like and think you may want to use it
again for other MultiView setups, you can save it as a template. Just
go back to the templates in the upper right and click Add. When you
load a new template it basically imports the settings you have created
for each layer. So, as you add new inputs to each layer, they will
automatically include the Zoom, Pan, Rotation and Crop properties
saved inside of that MultiView preset.
Once you know how to create a MultiView from scratch, it is just as
easy to create one from an existing input. This is great if you wanted
to add something like a logo or title to an image or video input.
Once you have a MultiView created, you can even use them within
other MultiViews. When creating a new MultiView and selecting the
inputs, you can choose existing MultiViews from the drop-down
menu.
There is really no limit to the creative ways you can use your inputs
to make scenes and templates with multiple inputs on one screen.
Even better, you still have access to your overlay channels for even
more options.
Pro Tip: Use your overlay channels when you want to quickly show
or hide inputs on screen. Use MultiView when you want to build a
more complex scene that will be a base layer in your production that
you can switch to.
Working with Titles

15
In an upcoming chapter, you will learn how to use the vMix GT Title
Editor to create custom animated titles. But before you dig into
creating custom titles, you should know it is incredibly easy to add
lower thirds and graphics into your vMix production by using the
included graphics in the Title/XAML input tab.
To get started simply click Add Input and select Title/XAML. Here
you will be presented with a variety of title templates that you can
choose from and customize. If the title has a little GT diamond in the
top left corner that means the title has been built with the GT Title
Editor and includes an animation. Select a title from the menu and
click OK.
Pro Tip: You can open these titles with the GT Title Editor and
customize if you wish. You can find them located in the vMix folder
on your computer inside of the Titles folder.

16
This will create an input inside of your vMix production for your
selected title and open the Title Editor. You can reopen this Title
Editor at any time by right clicking your title input. At the top of the
Title Editor you have options for editing the text. You can alter the
font, text size and color. The Data Source button allows you to map
custom data from sources around the world directly into your title.
Data sources will be covered in an upcoming chapter.

17
Many times, during a live production, titles have to be updated. vMix
provides a list feature which can be used to build lists of information
to quickly populate the titles when clicked on. You can use this
feature by entering information into the title fields and clicking the +
button. Each time you click the + button a new entry to the list will
be added. You can click the – button to remove entries. In this way,
you can quickly build a list and click the entry you would like to
display inside of your title without having to enter the information in
manually during your live broadcast.

18
Some titles include countdown timers which can be set up using the
Countdown Settings area. You can access Countdown Settings by
clicking the Settings button next to the Countdown playback
buttons. Many vMix producers connect Countdown timers with
shortcut buttons to quickly reset countdowns during sports games
for example. You will learn more about triggers and shortcuts for
countdown timers in an upcoming chapter.
Most countdowns start with a specific duration time. For example, you
can setup a duration of 30 minutes, click the play button, and your
timer will countdown from 30 minutes. You also have a number of
formatting options to customize your title. You can choose to show
different combinations of hours, minutes, and seconds in your titles.
You can choose to reverse your countdown and you can choose to
display the current time using the Clocks button.

19
Pro Tip: Try setting up a shortcut to start and stop a countdown in
your title.

20
3 AUDIO
An essential part of any great video production is quality audio.
Fortunately, vMix includes flexible and powerful audio tools and
controls. To see how it all works, start by adding a dedicated audio
source. Audio can also be included on all common video inputs. Still,
you may also want to add stand-alone audio sources like
microphones, audio interfaces, and mixers.
Add the Input
Click on Add Input and look toward the bottom of the left-hand
column for Audio Input. Click on that, and you can select the live
audio source you wish to use. From the dropdown menu, choose the
source. Before you click OK and leave this screen, look for the Mute
in Headphones checkbox. This is useful for any source that you do
not want to monitor in your headphones. For instance, when using a
live microphone to narrate a video production, some operators would
rather not hear their own voice in the headphone mix.

21
Changing Settings
The next thing you may want to do is click on the gear icon on this
new audio input source and go to the audio settings menu. The input
settings are different from the Audio Settings but inside the input
settings you can click Audio Settings to access the unique Audio
Settings. You can also access audio settings by clicking the input
settings cog inside the audio mixer.
Indicator and Levels
Now, as you look at your input in the input source window, you
should notice a green Audio button at the bottom right. That button
will be green whenever the audio is on. If the audio source is sending
a signal, you will also see that the levels next to the input are showing
up as green bars and inside of the audio mixer. You can click on the
Audio button to mute or unmute the audio. When you do this the
button will turn gray, and the level meters will turn gray.

22
Inside Audio Settings you will have the option to adjust gain and
delay for your source. You can also adjust the headphone volume or
click the green headphones to turn headphone audio off for this
input. There is a checkbox you can click remove the input from the
audio mixer. This is helpful to clean up your audio mixer and only
keep the input you need. The Audio Settings area also gives you
controls over Gain, EQ, Compressor, Noise Gate, a Channel Mixer
and a Channel Matrix. The VST 3 Plugins options will be reviewed in
the next chapter.

23
Master Levels
By default, all the activated audio inputs go to the master audio in
vMix. If you have an active audio source, you will also see levels for
the master audio mix shown next to the transition bar.
The Audio Mixer
By default, the Audio Mixer is located on the right-hand side of
vMix. If you do not see it on the bottom right portion of your
interface, look for the gray Audio Mixer button. If you click it, it will
turn green, and the mixer will appear below it. Any input that you
add will show up here with its own volume slider. It will have the
same name as it does in the input window. This entire audio mixer

24
can be undocked and moved. This is great if you are working with
multiple audio sources and need more space.
The audio mixer enables you to adjust the volume of each individual
source. You can also see the levels that will match those from the
source over in the inputs area. Also, when you click the green audio
button to turn off the audio on the input, you will notice the green
speaker also turns off in the mixer area for that source, and the levels
turn blue there as well. It works both ways. If you click the green
speaker, you can toggle the audio from that source on and off. That
will be reflected both in the mixer and on the input. This audio mixer
is also where you will find the master audio for which you can also
control the volume.
Other Options
Some other options found in the audio mixer include the settings
cog, which gives you access to the advanced audio settings for that
input. These include audio effects and control of the delay, which can
be useful for syncing your audio with your video. Audio sync issues
are common and vMix makes it very easy to apply audio delay to
individual inputs in order to sync your audio and video.
If you have audio sync issues, it is most likely an issue that audio
delay can fix. Depending on your computer and audio-visual
connections latency between video and audio inputs can vary. Usually
video sources can take just a little more time to process than audio
due to higher bandwidth requirements. To fix this issue, try adding a
delay to your audio inputs in increments of 25 until the issue is
resolved.
Pro Tip: Included in the online course you will find an Audio Video
Sync Tool. This is a video that you can use to determine the exact
amount of latency you should apply to your audio sources.

25
Below the gear is the S or Solo button. This allows you to listen to an
individual source in your monitors or headphones, which is helpful
when you need to hear one source separated from the other audio.
Below the Solo button you will find the “Automatically Mix” button
represented by two arrows. This button will automatically mute and
unmute the audio of an input as it enters the output area. Next in the
list you will see a quick mute and unmute button represented by a
speaker. At the bottom, you will see an M button. That stands for
Master. It means that this input is being routed to the Master audio
for the production. If you have additional audio outputs set up you
will be able to route audio to those outputs with these buttons. For
example, you may want to set up a second audio output to send
audio to a video conference software like Zoom.
Automatically Mix Audio
One of the most significant issues facing new vMix users is
understanding how to control whether an audio source is active all
the time or only when that video input source is active. For example,
you may have some sources, like a host's microphone, that should be
active all the way through a production. On the other hand, you may
have a video with audio that should only become active when
switched to the output window. vMix makes it very easy to choose
how the audio for each source will function. It is also very easy to
change the preference for each source. You can do this by going to

26
the input settings for an input source and checking or unchecking the
Automatically Mix Audio box. You can also toggle this on and off
on the mixer by clicking the button with two arrows.
Audio Plug-ins
The ability to use third-party audio plug-ins give vMix users access to
a massive collection of tools to help create professional-quality audio
for their live productions. VST (Virtual Studio Technology) uses
digital signal processing to recreate traditional audio hardware often
found in professional audio studios. Now with vMix and VST,
producers have access to the sound of high-end compressors,
expanders, reverb units, delays, equalizers, effects, and more.
First Things First
Before you dive into audio plug-ins, there are a few things to double-
check. First, be sure that you have vMix version 20.0.0.41 or higher.
Also, keep in mind that vMix supports VST 3 64-bit plug-ins. You
will find many VST and VST 2.0 plug-ins on the market, but for
stability and reliability, look for VST 3 64-bit. They are available from
many vendors, including waves.com. One of the most important
things to remember is to carefully test these plug-ins before you go
live with them.
Downloading and Installing
If you are looking for high quality and affordable VST 3 plugins, I
highly suggest Waves.com. Two audio plugins I consider must haves

27
are NS1 (for noise suppression) and Renaissance Axx (A plugin to
make voices sound more robust). Once you find a plug-in that you
are ready to test out, go ahead and download it. Most downloads will
come with an installer that will automatically place the files where
they belong, usually: program files/common files/VST 3.
Now that the plug-in is installed, open up vMix, and you can see how
to add it. You can add plug-ins to both individual inputs and to your
master audio. There may be instances where you want to apply
specific vocal effects to a microphone input such as reverb and a
general effect to the master, such as a compressor.

28
Go to the audio mixer and click on the gear icon on either the master
or an individual input to open the Audio Settings “Plugins” tab.
Now click on the + button to add a plug-in. Select a driver from the
dropdown menu and then choose from any plug-in associated with
that driver from the next drop down and hit OK. That will bring up
the editor screen for that specific plug-in.
Different types of plugins have different interfaces. Some show a
graphical interpretation of the physical version of the hardware, and
others have simpler interfaces. Usually, once you add the plug-in, if
that input has active audio, you should be able to hear it and adjust in
real-time in the editor. Once you have it set up the way you want it,
you can save a preset within the plug-in to quickly load it later.
Pro Tip: Many plugins come with presets you can use for various effect
settings. For example, for voices there may be a male and female preset. This
is often a great place to start your project.
Once you have your plug-in set up, you can make them easily
accessible by setting up shortcut keys. You can even control them
from a midi-controller, X-keys, or vMix web controller.
Audio Plug-ins are a great way to improve the sound of your live
production. However, if you are new to them, they can be a bit
overwhelming. If you want some guidance about what plug-ins work
best with vMix, check out some of the online forums on vMix.com.

4 VMIX BASICS
vMix Settings
The Settings menu, accessible in the upper right-hand corner of the
vMix, gives you access to advanced features and settings. The most
basic users will not likely ever visit many of these settings, but it is
helpful to have a basic overview of what is available and where to
find it.
On opening the Settings menu, you will see the 14 setting categories
down the left-hand side. At the very bottom, look for the Import,
Export, and Default buttons. These are you moving or duplicating
your setup to another computer. Using Export will create a file with
all the configurable settings. Import will load that file into another
instance of vMix if it is the same version. Default will return all the
vMix settings to how they were when the software was first installed.
Here are the settings options available inside of vMix.
Display

30
These are the master settings for the vMix output. You can set the
master output size, frame rate, and aspect ratio. You can also change
the interface's theme colors and adjust the setting on the Fullscreen
output(s). Here you can select the monitor vMix will use for your full
screen output.
Outputs/NDI/SRT
This is where you can adjust the multiple vMix outputs, whether via
your graphics card or over NDI. The number of outputs is defined
by the edition of vMix you are running. You can choose sources for
your full screen outputs here or via the “Fullscreen” button at the
center area above the transitions bar.
You can also configure NDI (Network Device Interface) outputs
which are IP video streams that are made available over your local
area network (LAN). You can choose to turn on up to four unique
NDI outputs in addition to enabling all camera sources, vMix calls,
and audio inputs/outputs. In this way, you can make almost any
source in vMix available to other computers on your network. By
clicking the settings cog next to each NDI output you can configure
the NDI outputs audio channel, resolution and video settings. You
can even enable SRT outputs in this area with quality setting and
latency options.

31
Options
This area includes many of the general preferences for vMix. These
include the preferred language, the layout of the interface, and how
the software behaves on startup and during a recording or streaming
session. One new feature in Options will enable Production
Clocks.

32
Once enabled a Production Clock will appear underneath the
transition bar area. You can double click this box to bring up it’s
settings options. Production Clocks allow you to quickly reference
the time and a custom countdown time based on an event. You can
also keep track of the time you have been recording or streaming.
Performance
The Performance settings tab is where you can select the graphics
card you will be using with vMix. It is here you can enable Low
Latency Capture and High Input Performance Mode. You can
also access settings that will alert you when your CPU or GPU is
pushing its limits. This is helpful so you can address any issues that
may lead to poor performance or dropped frames.
Pro Tip #1: In addition to enabling your graphics card for use with
vMix, check to see if your graphics card has been updated. For
NVIDIA graphics cards for example, you need to open the NVIDIA
Control Panel and add vMix as a selected program in the 3D Settings
Area.
Pro Tip #2: If you are using a Windows laptop check out your
battery settings. In “Power Options” you can enable “Performance
Mode” which will greatly increase the performance of your laptop
and its ability to run vMix smoothly.
Decoder
This section is for specifying what decoders will be used to playback
certain video file types. In most cases, these can all be left at their
default settings.
Recording
Here you can specify the default folder where recordings will be
stored and the format for the filename. You can also set the size for
the recording memory buffer. This may be useful if you have an older
mechanical hard drive and are experiencing dropped frames during
recording.

33
External Output
This is where you can access advanced settings for the available
external outputs in vMix. Remember, most editions of vMix offer
one external output, whereas 4K and Pro offer a second output. The
External output can be used to enable a virtual webcam driver used
to send video into additional programs such as Skype or Zoom.
Audio
This includes several preference settings, including a master setting
for the Automatically Mix Audio setting. You can also turn off and
on the audio meters for both the master and the individual inputs.
There is an option to fade the audio entirely along with the video
when Fade to Black in selected. Finally, there is a setting for a default
audio delay across all inputs, which can be useful for dealing with
syncing issues at a master level.
Audio Output
This controls the routing settings for the master output and
headphones. You can also configure the seven auxiliary audio buses.
Any of the outputs can be set to various output channels, including
mixes for surround sound. Here you can also select the default audio
bus for new inputs as they are added. Once you add an audio output
it will show up as an audio routing option in the audio mixer.
Web Controller
This area contains everything you need to set up and use the vMix
web controller. This is a web-based controller that you can use to
switch vMix inputs, use shortcuts, edit titles, setup tally lights, and
interact with the API. You can access this controller from any
computer on your LAN using the web site address provided. You can
optionally set up a username and password to restrict access to this
controller. The Web Controller will be covered in more detail in an
upcoming chapter.
Tally Lights

34
While there are other options for using tally lights, this section
includes the settings for a tally light system based on Arduino
hardware. Unless you are using such a system, you can ignore this
settings tab.
Shortcuts
This is where you can set up, store, and edit shortcuts for nearly any
function within vMix. Shortcuts can be assigned to the keyboard,
MIDI device, and other control devices. Shortcuts will be covered in
more detail in an upcoming chapter.
Activators
With activators, you can activate lights, buttons, and even motorized
faders based on changes in vMix.
Scripting
For advanced users running 4K or Pro editions, this is where you can
add and edit custom scripts.
vMix Full Screen and MultiView
There are lots of ways you can output video from vMix. You may be
considering using vMix for live streaming or recording. Still, you may
also want to send signals to projectors or external monitors. This
could be for IMAG (image magnification) or simply to enhance
production workflow by viewing the output, preview, or program
views in an external monitor. In some studios, full screen outputs are
used to power confidence monitors used by on screen talent.
Fullscreen
One way to handle external video is through the Fullscreen button
located at the top center of the interface. There are many options for
what is fed to this output. It can be connected to a monitor or
projector through your computer’s graphics card.

35
With vMix, it is recommended that you use a dedicated GPU
(graphics processing unit). The software is optimized to take
advantage of this additional processing power. It will take some of
the workload off your CPU which can lead to better performance.
These cards also tend to have multiple outputs. That allows you to
take advantage of the numerous ways you can output video from
vMix.
Before you get started with Fullscreen, connect the additional display
to your graphics card and be sure Windows recognizes it. In the
Windows Screen Resolution control panel, configure it to “Extend
these displays.”
With most production setups, you will have one output from your
graphics card connected to a monitor to display your vMix interface
for switching and control. With the additional screen connected, you
can use the Fullscreen option and decide what will go to it. With
vMix 4K or Pro, or the fully functional trial, you can add two
Fullscreen outputs.
First, in the Settings section, click on Display and choose the display
output you want to use for Fullscreen. Next, determine what you
want to be sent to this display. By default, it is the final mixed output,
but there are other options. Click on the down arrow on the
Fullscreen button and choose from Output, Preview, MultiView,
or any of the inputs you have set up in your input area.
MultiView

36
MultiView is an excellent option if you want an external monitor to
display multiple input views. For instance, a typical setup might have
the preview window, the output window, and eight commonly used
inputs. Suppose another display shows up to 16 inputs at once. You
could choose to have all your inputs displayed in the MultiView. To
adjust what is shown in the MultiView, go to the settings menu, select
Outputs/NDI/SRT. Under MultiView Layout, choose the general
layout and then click Customize Layout to specify what should
appear in each window of the MultiView.
Full Screen and MultiView are powerful features within vMix that
give you a new level of flexibility and control. The more you dig into
the features of vMix, the more important these viewing options will
become.
Recording Video with vMix
vMix is a comprehensive solution for live production and live
streaming. It also has powerful recording capabilities and can create
numerous types of high-quality video files. Some users employ vMix
mainly for the recording options. “Live to tape” productions are
produced like a live show but recorded a broadcast in the future. Live
event producers can record a high-quality file for backup, create
other productions from recorded footage, or offer viewers an on-
demand version after an event.

37
All editions of vMix offer numerous recording options. Still, with 4K
and Pro, the functionality is expanded with options like MultiCorder,
ISO recording of individual inputs, and instant replay.
Storage Space
One critical thing to keep in mind is that recording can use an
enormous amount of disk space. It is an important consideration as
you consider the type, quality, and length of the recording you will be
doing. Be sure you have plenty of disk space, preferable on an SSD
(Solid State Drive). Or investigate the external recording options that
are possible with vMix. You can also setup additional computers to
record outputs using NDI.
The main factors affecting recording files sizes are the format you
choose and the bitrate you select. Some “lossless” video recording
codecs such as AVI, create very large files. AVI and vMix AVI are
the highest quality codecs and require the most storage space. MP4,
WMV, and FFMPEG all allow you to adjust the bitrate to reduce the
file size. By far the most popular codec is MP4. When you choose
MP4, you can select the resolution, frame rate and bitrate. I have
found that between 8-12 Mbps is great choice for quality and file size.
Those who care very much about quality may increase the bitrates to
50-100 Mbps.
Pro Tip: vMix AVI is fault tolerant meaning that if you lose power
you can still recover your video recordings.
Testing
It is also essential to test everything multiple times. This is especially
crucial if you are working with new settings, recording multiple
outputs, or recording and streaming at the same time.

38
Recording Options
To see the many options available for recording, click on the gear
icon next to the record button on the bottom left of the screen.
Down the left-hand side, you will see the various file formats
available to you. There are pros and cons to each file type. You will
want to do some research to see what file type works best for your
available resources and what you intend to do with the recording.
If you are not sure, or just want somewhere to start, MP4 is a widely
popular option. It offers high-quality recording with reasonable file
sizes. MP4 files can also be uploaded directly to video sites like
YouTube or Facebook, with no conversion necessary. Even better, if
you have a newer NVIDIA video card, the encoding can be done via
the graphics card to free up some resources from your CPU. You
can enable hardware encoding with the check box next to your
recording profile.

39
Recording Settings
Once you have selected your filetype, you will see the multiple
settings for the file. You can choose a location and name the file,
choose the resolution, and set the bitrate. Below that, you can select
the profile, which is especially critical if you are going to use your
GPU for encoding. You will need to be sure the profile will work
with your specific graphics card.
Further down, you can choose the audio source that will be recorded
with the video. If you are unsure, leave this set to master. You can
also set a delay for the audio if you need to do so to get it in sync and
set the bitrate for the audio.
At the bottom, there are two important options. One allows you to
start a new recording at a set interval of minutes. This is helpful if
you are creating a long production and want more manageable files to
work with. To the far left is the WAV File Record button. This will
create a separate WAV audio file of your entire recoding. This is
perfect is you just want an audio backup or intend to use standalone
audio for a podcast or other audio medium.
Once you have all your recording options set, it is as easy as clicking
on the Record button at the bottom. You can also connect this to
any triggers, shortcuts, or manual buttons you want to use. The
record button will turn red, and you will see a red REC indicator at
the top of the screen. When you are done, just click the Record
button again to end the recording.
vMix MultiCorder
The vMix MultiCorder is a tool you can use to record multiple files at
the same time. The MultiCorder is only available in 4K and Pro
editions of vMix. You can use it to record raw video and audio from
any capture inputs available inside of vMix in addition to the main
produced video recording which would include overlays and
graphics.

40
MultiCorder has the following minimum system requirements:
• Solid State Disk (SSD) for storing recordings.
• Intel Core i7 Quad Core processor or higher
• High end graphics card with at least 1GB of on board memory
You can use the vMix MultiCorder to record video in AVI, vMix
AVI MKV, MP4 and FFMPEG formats. You can configure your
MultiCorder by pressing the MultiCorder settings cog which is
located at the bottom of the vMix interface. Here you can select the
inputs you would like to record and configure the format you would
like to use. Once you have configured the MultiCorder you can click
it to start all of your isolated recordings.

41
Live Streaming with vMix
One of the most popular features of vMix is the ability to stream live
productions over the internet. vMix makes live streaming simple and
offers many powerful features and customization settings to help you
get the most out of your live stream.
There is an ever-growing list of live streaming providers from free
social media sites to paid professional content delivery networks.
Each has its own feature set and its own technical requirements.
Getting Started
To get started, click on the gear icon next to the Stream button at the
bottom of the interface. At the very top of the dialog box, you will
see the Profile section. This will enable you to save and recall specific
streaming settings. This is perfect is you find yourself using different
providers and settings for various productions.

42
Right below that, you will see boxes for streams one, two, and three.
Every edition of vMix enables you to stream up to three platforms
simultaneously.
Choosing Your Provider
In the destination field, you will see an updated list of live streaming
providers. You will likely find your provider on the list. However,
since new providers are popping all the time, yours may not be on
there. Do not worry, you can always set up your stream manually. To
do that, choose Custom RTMP Server and enter the URL and stream
name or key provided by your streaming provider.
If your provider is on the list, select it, and you can log into your
streaming or social media account directly. You will notice that some
of the dialog boxes are slightly different at this point. However, with
most, you will just sign in and add some information. Some providers
offer you multiple channels to stream to. Once you log in, these will
be available from a dropdown menu.
Stream Settings
Once you are signed in and have entered any necessary information,
you can choose your stream's quality. Depending on your edition of
vMix, there are multiple presets ranging in quality from 360p to 4K.
Most live-streaming platforms will give you suggested guidelines, and
you are likely to find what you need on this list. However, if you need
something different, you can choose any of the presets, click the gear
icon, and change the settings.
When considering the quality of your stream, you will mostly be
looking at resolution and bitrate. Your choice should be based on
your provider recommendations, the quality of your production, and
your internet connection's speed and reliability. Most streamers want
their resolution to match the resolution of their production, especially
when it comes to HD and 4K productions. They also want to use as
a high of a bitrate as possible. However, this can lead to trouble if the
internet connection is not fast enough.

43
Accounting for Network Resources
Your upload speed needs to be higher than your bitrate, or you will
drop frames, and the stream could fail. It is a best practice to use a
bitrate that is one half of your upload speed or less to leave room for
network fluctuations. It is essential to know your internet speed and
test it. When testing your internet speed, be sure to do so under
similar conditions as when you will be streaming. For instance, if you
are sharing a network with other users, you will want to test while
using the network resources at the same level as your production
time.
Bandwidth is measured in bits and the word “bandwidth” is
used to describe the maximum data transfer rate of your internet
connection. One megabit = 1,000 kilobits. Your internet speeds are
measured in upload and download speeds. Megabits are used to
measure the size of the bandwidth pipeline between your computer
and the internet.
Resolution Pixel Count Frame Rate Quality Bandwidth
4K 30fps 3840x2160 30fps High 30Mbps
4K 30fps 3840x2160 30fps Medium 20Mbps
4K 30fps 3840x2160 30fps Low 10Mbps
1080p60fps 1920x1080 60fps High 12Mbps
1080p60fps 1920x1080 60fps Medium 9Mbps
1080p60fps 1920x1080 60fps Low 6Mbps
1080p30fps 1920x1080 30fps High 6Mbps
1080p30fps 1920x1080 30fps Medium 4.5Mbps
1080p30fps 1920x1080 30fps Low 3Mbps
720p30fps 1280x720 30fps High 3.5Mbps
720p30fps 1280x720 30fps Medium 2.5Mbps
720p30fps 1280x720 30fps Low 1.5Mbps
The chart above displays various bitrate/bandwidth choices you will
have for your live streams. Using this chart and your available

44
uploads speeds, you should be able to map out the number and
quality of live streams your internet connection can support. A
general rule of thumb says that you should only use half of your
available upload speeds for live streaming (Download speeds don’t
help us with live streaming). Therefore, if you have 10 Mbps of
available upload speed, you should only be live streaming with 5
Mbps. Leaving headroom in your upload speeds protects stream
from fluctuations in the internet connection which can cause
interference with your stream’s consistency. Keep in mind that if live
stream to multiple locations at the same time, you are adding to your
overall upload bandwidth.
Think about your live stream resolution as the size of your canvas.
The bitrate that you select is the amount of data that is used to fill
that canvas. Therefore, you can have a high-quality 1080p stream
with a bit rate of 6 Mbps, or you can have a low-quality 1080p stream
with a bit rate of just 2 Mbps. Today, most people will expect at a
minimum of 720p video and a bit rate of at least 1.5 Mbps. New
reports from Akamai show that most people watching 1080p video
find that 6Mbps looks like excellent quality.
So, you may have a choice between live streaming a single high-
quality video stream, or multiple live streams of lesser quality. For
example, if you have 10 Mbps of upload speed, you may create a 3
Mbps stream to YouTube and a 2Mbps stream to Facebook. If you
are concerned about creating a single high-quality stream than you
would only stream to YouTube using 5Mbps. Keep in mind that you
can always record an high-quality recording to your local hard drive.
Many production experts will record a “high bitrate” mp4 files
ranging from 12-100 Mbps. The recordings saved to your local hard
drive can be of higher quality than the live streamed recordings
available on YouTube and Facebook.
Starting the Stream
When all the settings are the way you want them, you can click Save
and Close. You can start your stream from that same window or just
click the Stream button on the bottom of the screen. The button will
turn orange as it is connecting and the turn to red. If there is a

45
problem with the stream at any point, the indicator will turn to
orange. When you are done, hit the button again, and your stream
will end.
Pro Tip: If you are live streaming to multiple destinations you can
start all of them at the same time by clicking the Stream button. If
you want to start each stream at different times, open the Stream
settings area and click the individual stream start buttons.
Video Overlay Channels
Overlays, available in vMix, are a great way to add depth and
dimension to your live video productions. With the touch of a button
or click of a mouse, you can overlay multiple graphics and other
inputs over your main output layer. You can produce the same look
as professional broadcast studios with lower thirds, picture in picture
videos, and much more.
Getting Started with Overlays
To get started, be sure you have the graphic, video, or camera added
as an input in the input area. You can add it to the output as an
overlay by clicking on the selected overlay number at the bottom of
the input box. Depending on the edition, there will either be one or

46
four options. If you are using the Basic or Basic HD editions, you
will have access to one overlay channel, HD and higher offer four. If
you are using the free trial, you will have access to all four.
Overlay Behavior

47
To determine how each overlay channel will behave, click on the
Overlay button at the bottom of the screen. This will open up the
Overlay Settings. Choose the overlay channel you want to work
with from the dropdown menu in the first field. Next, choose the
type. For titles and lower thirds, you will usually want to choose full
screen. You can also select picture in picture to make the overlay
channel resize the selected input and scale it as part of the effect.
Next, from the Effect dropdown, you can choose a basic cut
transition or choose from multiple transition effects. Below that, you
can select the effect duration, which will determine how long the
wipes, fades, or other effects will last. If you are using a basic cut, the
software will ignore the duration setting.
Next is the duration of the overlay. This is how long the overlay will
stay on the screen after it is activated. If you want to control this
manually, just set this to 0. The next two settings are for the more
advanced stinger transitions that add animation to the transition. The
alpha setting is also available in the event of using transparencies in
overlays.
For picture in picture options, the bottom half of the settings box lets
you position your overlay element on the screen. You can adjust the
size and position using your mouse, dragging to move the position,
or clicking and dragging to adjust the size. You can also use the
zoom, pan, and rotation sliders on the left side. At the very bottom,
you can add a border and adjust its color, thickness, and radius.
Once you are done, hit OK. Now when you hit the number of that
overlay on any of your input sources, that source will appear as you
selected over whatever is in the main output window. It will match
the transition settings, positioning, and duration you have set.
Mindful Video Production
As a vMix operator, it’s important to think about your production
from the perspective of the technical director. It can be helpful to
think about your production as an orchestrated process of capturing

48
the show's content with your audiovisual equipment. To do this, the
technical director must make decisions about how and when to
transition between the available video and audio sources. The goal of
a good technical director is to produce a cohesive and captivating
storyline. As you transition between one scene to the next, it is
important to think about the viewer's experience as they follow along
with your production. Choosing the appropriate moment with the
appropriate transition type, is essential in capturing your audience's
attention and making the story flow seamlessly.
Producers can use transition effects to complement their production
capabilities. A good transition is transparent in the way it leads the
audience through one scene to the next. In a perfect world, the
transition happens as if the viewer naturally selected it themselves. To
do this, your production should flow in a way that feels natural to
viewers.
Be careful not to use too many fancy transitions that could take away
from the main message of your content. Below are the four most
popular transitions used in video production. In order of popularity,
these transitions would be the cut, the fade, the fade to black and the
stinger transition effects.
Type Most Used
Cut 90% of the time
Fade <5%
Other <5%
You will notice that there are quite a few options in vMix when it
comes to video transition effects. The most used video transition is a
cut. The cut simply switches two video sources in a direct cut
transition without any noticeable special effects. The cut should be
used for transitioning between most of your prepared content. The
cut is perfect for transitioning between two live camera angles in the
same scene.

49
When you are cutting between multiple camera angles in one scene, it
is important to think about the order in which you switch camera
inputs. Jumping to too many different camera angles, too quickly
could be disorienting for your viewers. A good technical director will
visualize the camera angles that they have available and move
through them in a natural order. You should try to arrange your
cameras angles so that you can reveal additional details as they
become more important to the story. If you have a pan, tilt, and
zoom camera that can capture multiple angles during a single
production, consider switching back and forth between close up
angles and available wide-angle shots. Generally, you do not want to
cut to a camera angle that is more than 45 degrees away from your
current camera angle. In this way, you can switch between multiple
cameras in an arch to finally reach a camera that may show a side or
behind the scenes camera angle.
Interview Diagram #1
To study these production techniques, use the example of a two-
person interview. When you are producing an interview like this, it is
a good idea to start with a wide angle shot that displays both of your
subjects in the same shot. This is your central shot that establishes
placement for the viewers in the scene that they are watching. The
cut transition can then be used to enhance the viewer's perspective of

50
each person as they take turns talking. A transition like a fade or a
stinger would look unnatural during a two-person conversation. It
would make sense at the end of a conversation when you cut a
commercial break. The cut makes the camera switching feel natural
and unnoticeable because it happens in the blink of an eye. Each
transition should be timed to flow with the conversation your
subjects are having.
Interview Diagram #2
In interview diagram #1, the producer selected camera cuts that are
sequential around the arc of camera options moving
counterclockwise. Interview diagram #2 there is a sequence of
transitions that do not follow sequential movements around the
camera inputs. Diagram 2 breaks the 45-degree rule and risks
disorienting viewers.
Using these types of “jumpy cuts” usually results in an unprofessional
looking production. Remember that all rules are meant to be broken,
and every camera setup is different. Use your instincts and create a
production that makes sense for the story you want to tell. Just
remember that the transition decision are an important part of video
production.

51
The Crossfade
The crossfade transition is perhaps the second most popular
transition in live video production. You will notice it being used less
frequently than the cut. Crossfade transitions can produce beautiful
artistic visual effects and should be used to create visually engaging
content. Crossfades are used frequently during musical performances.
Think about the national anthem performed just before a sports
event. You will notice the crossfade is used when the cameras switch
between a close-up of a singer and a wide panning shot of a crowd.
You will notice great crossfade transitions that feature flags slowly
fading into a crowd of singing sports fans.
If you have an artistic shot prepared for your next video production
project, the crossfade may be the most appropriate transition to use.
If you have a pan, tilt, and zoom camera, try transitioning with the
crossfade when the camera is in between a slow pan. You will learn
more about automated PTZ camera controls inside of vMix in an
upcoming chapter. Many professional broadcast studios use a
physical T-bar to create custom cross-fade transitions between
multiple video inputs. Use this transition sparingly and note that
crossfades may look pixelated in low bitrate bandwidth streams.
Pro Tip: You can connect USB T-Bars to your Windows computer
and program them to control the crossfade transition in vMix. Check
out the XKeys XKE-124 TBar.

52
The FTB (Fade to Black)
The fade to black sometimes shortened to just “FTB”, is perhaps the
next most used video transition. You can fade to black and fade from
black to notify your audience of the end of your production. This
type of video transition clearly demonstrates the nonverbal
communication power you have as a producer to close a scene. Try
using the fade to black transition to close a unique scene or segment.
If you can time your fade to black with the ending points of an audio
track, or fade audio down it will help emphasize your production.
Using Stinger Transitions
Finally, the stinger transition is an animated transition that everybody
has grown to love. The effect combines a transparent video
animation that evolves into a full screen transition which is timed
with a cut. When your stinger video animation starts playing on top
of your current video, you can program vMix to cut to your preview
input exactly when the video completely covers up the current scene.
The stinger effect has been made popular by sports broadcasters who
use the effect to notify the audience of a particular scene change. In
this way, sports broadcasters have trained their audience to expect a
stinger transition when an instant replay or prepared video screen is
coming up. Really fancy stinger transitions often include perfectly
timed audio which is included with lots of “whooshes” and “pops” to
give the animation a realistic look.
Pro Tip: Use the Multiview feature inside of vMix to add audio to
your Stinger Transision. Click the “Automatically Play with
Transition” and you can combine audio with your stinger transitions.
Making a Stinger Transition
Stinger transitions can be made with “vMix Video Tools” which is a
Windows application installed with the main vMix application. This
application is used to create an image sequence from a transparent
video file. This method of creating stinger transitions is an efficient
way to manage stinger transitions because the vMix Video Tools to

53
break down a transparent video file into a sequence of PNG files
which is smaller in size and more efficient.
To create a Stinger transition, start by looking for a video with a
transparent alpha channel background. MP4 files will not work. You
should be looking for MOV or AVI files. Videoblocks.com is a great
place to look for video content. Or you can create your own stinger
transitions with a video animation software such as Adobe After
Effects. When selecting a stinger transition video file, looks for an
animation that eventually takes up the entire screen. This is the point
where you can set up your stinger to transition to your preview input
without the audience noticing.
Once you have a video selected you can select “Create Image
Sequence” inside of vMix Video Tools and select your Source File
and Output File. Once you load in your video, click Convert. This
will create a folder on your computer with your Image Sequence that
you can use to setup a Stinger inside of vMix.

54
Inside vMix, you can Add Input and selecting the Image
Sequence/Stinger. Once your image sequence has been loaded into
vMix, you can click into the overlay section of vMix to set up the
stinger details. vMix allows you to set up two unique Stingers in a
single production. The most important detail inside the stinger
options is the stinger cut point. You can test out your stinger a
couple of times to tweak its performance to match the cut point
where your animation covers the entire screen fully. In the overlay
settings area, you will find multiple tools allowing you to set up the
stinger duration, cut points and even its alpha channel properties.
Using Multiple Channels
You can use all four overlay channels at the same time. For instance,
if you wanted to add a lower-thirds title, picture in picture video, a
graphic, and even another video, you can use all the channels. For
even more flexibility, you can use overlay channels with input
MultiView sources. You can create a scene of up to ten layers and
then assign that to an overlay channel.
Other Features
There are a couple more features of the overlay channels you may
find helpful. They both work via a right mouse click. To see and

55
overlay in the preview window, right-click the selected overlay
channel on the input you wish to use. When use transition from the
preview window to output, the overlay will transition as well. Finally,
with a right mouse click, you can zoom a picture in picture overlay to
full screen. Once you have clicked the overlay number to add the
input as an overlay, simply right-click the same button to zoom it to
full screen. Another left-click will turn the overlay off.
Using vMix Social
vMix Social is an easy way to bring social media content into your
live production. With social becoming such a big part of events, these
tools will save you time and make sharing social media posts and
reactions an integrated part of your production.

56
Getting Started
To get started, go to Add Input and add a new title. Once you have
selected the Title tab, you will see all the available title layouts. Click
on the Social tab at the top. You can create your own custom social
media title layouts, but you can also use one of the available
templates. This will become the placeholder for the information that
will come from vMix Social.
Once you select one of the social titles, you will see how they have
been created specifically for social media. The title editor has ready-
made fields for the type of information you will want to share from
social media. These are placeholders for things like profile pictures,
usernames, and social media messages. Some of the templates have a
place for a title field. This is something you can enter in this editor,
and it will remain the same no matter the data received from social
media. Click on the X in the top right to close out of this window. If
you want, you can click on that new title input and put it in the
preview window to see what it will look like.
Connecting Social Media Accounts
Now it is time to connect to social media platforms to begin
populating those fields. Open vMix Social by going to the
hamburger menu in the lower right corner of the interface. It will

57
automatically connect to vMix and show “Connected” in green at the
top of the dialog box. Below that, you can see all the currently
supported social media platforms. Keep in mind that these are
subject to change. Social media sites are continually changing their
access rules and processes, and some may become unavailable while
others may grow in popularity and be added.
You can choose one social media platform or as many as you want.
Clicking on each logo will give you access to the settings for that
platform. You will see that each settings box is different since the
various platforms have different login processes and search
parameters.
Take Twitter, for example. To get connected, you will log in and then
be provided a PIN by Twitter, which you will enter in the next field.
Once you are logged in, you can choose your feed type. You may
want to collect Tweets around a particular hashtag or search phrase,
show a specific timeline, or even favorited tweets. Below that, you
can enter your search term or username and make some other
preference selections.
You can go ahead and repeat this process for any of the social
accounts you wish to use. For Facebook, Twitch and YouTube, you
can login to your accounts and select your specific live stream to

58
receive comments from viewers. Once everything is set up and ready
to go, you can add your social media title to your production using
one of the overlay channels, keeping it in view all the time or only
selecting it when you want it to be seen.
Comment Moderation
Of course, in most cases, you will want the opportunity to moderate
social media posts and comments before they appear in your live
broadcast. That is easy to do with the vMix Social web interface.
Copy the URL from the vMix Social box into a web browser on any
computer or device connected to the local network. The easy to use
interface will allow you to select and approve content and send it
directly to vMix, where it will appear on the social media title slide
you created.

59
The specific title that will receive this information is the one that you
select in the vMix Social application. You have the choice to Send
comments directly into that title or build a list that you can manage
by using the Add to Queue feature. Many times, you may receive
great comments, but you are not ready to share them with your
audience. Using the Add to Queue feature you can View Queue at
any time to Send comments directly to your title from your curated
list.

5 ADVANCED VMIX FEATURES
vMix Shortcuts
As your live productions become more complex, vMix makes it easy
to access commands via your keyboard or MIDI device using
shortcuts. Nearly anything you can do in vMix, you can do with just a
keystroke or button press.
Getting Started
To get started, just click on the settings button in the upper right
corner of your interface. Then select Shortcuts from the options in
the left column. If you have yet to set up any shortcuts, you will see a
blank screen. Across the top, you will see tabs for the multiple
options for assigning shortcuts to different devices, including the
keyboard, MIDI controller, control surface, ShuttlePROv2, or
joystick. Start by learning how to set up a keyboard shortcut.
Setting Up a Keyboard Shortcut

61
Click the Add button at the bottom of the screen. That will open up
the Add Shortcut dialog box. You can either type in the key in the
Key/Control field or hit the Find button. If you hit the Find button,
another box will open and wait for you to press a key. Once you do
and it is correct, press OK.
The next field down sets the function for that key. Click the down
arrow to see all possible functions arranged by categories. Click to
choose the process you wish to assign to that key. Next, you can
select the duration for transition effects. Then, select the input you
would like to apply the transition to. That can either be the preview

62
window or any of the existing inputs. By ticking the box below, you
can assign the shortcut to a specific input number.
You can then add a title and description to the shortcut and
determine whether this will be a global shortcut available anywhere in
vMix or local, assigned only to the current preset. You can also tick
the box if you want this preset to be available in the vMix web
controller. Then just click OK.
Once you have shortcuts set up, you can go to the shortcuts menu to
add new shortcuts, edit, or even clone existing shortcuts. During the
cloning process, you will find that you can assign multiple shortcuts
to the same key. This is useful if you want to trigger multiple
functions with one click.
Setting Up Shortcuts on External Devices
The process of adding shortcuts for a MIDI device, control surface,
ShuttlePROv2, or a joystick is similar. Before starting, be sure that
your device is connected and set up in vMix. From there, simply click
Add. Next click Find and then press or activate the button you wish
to use. The rest of the process is the same.
If you want to set up a lot of shortcuts at once, you may want to look
at the templates found at the lower right corner of the shortcut’s
menu. There are multiple templates for keyboards, MIDI devices,

63
and other controllers. They come preloaded with functions assigned
to keys, but they are entirely customizable to fit your specific needs.
Using GT Title Designer
Titles can be an essential part of your live video production. They can
identify guests, introduce segments, and share additional information
related to your production. vMix GT Title Designer creates dynamic
titles without overtaxing your computer’s CPU. That is because the
vMix GT Title Editor is GPU based. The designer is available in all
editions of vMix. In 4K and Pro, you have the option to create
custom animated titles and import Photoshop files directly in the
PSD format.
Getting Started
Load the GT Title Designer by locating it in the hamburger menu on
the bottom right of your screen. The default resolution for a new
design will be 1920x1080. If you want something different, just go to
File in the upper left corner, click New, and you will have the chance
to set the resolution.
You will see all the different elements you can use to design your title
down the left-hand side of the screen. The images represent text,

64
rectangle, circle, triangle, image, 3-D text, ticker, and QR code. You
can select any of the options, then click and drag on the canvas to
place it and determine the size.
Once you add an element, you will notice on the right side that it
appears under layer one. You can create additional layers by clicking
the + button at the top of the layer box and remove them using the -.
Customization Options
Once you have placed an element on the canvas, you have several
options for customizing it. For instance, if you place a shape such as
a rectangle on the canvas, you can use your mouse to move it around.
Hovering over the edges will allow you to drag to resize. Right-
clicking on the object will reveal several options, including changing
the fill to a different color or image, adding or editing the stroke
outline of the object, sending it forward or backward within the layer,
aligning it, or docking it to a specific part of the canvas. You can also
create a group layer that will allow you to manipulate multiple objects
at once and align them with each other.
There are more options available across the top of the editor,
including styles that allow you to choose from some preset options.
The format tab provides more specific settings for location,
dimensions, rotation, and rounding. The effects tab offers options
like opacity, shadow, and reflection.
Adding text is like adding a shape. Just select the text option and click
and drag to add it to the canvas. Selecting text and clicking on the
Home tab at the top will bring up text options such as font, font
size, color, alignment, and stroke.
Some experimentation with the interface will help you see all the
options you have for manipulating shapes and text. Many users will
find most of the options like Microsoft Word or PowerPoint.

65
You can decide if you want this title to hold the actual text you want
to display or a placeholder so that it can be edited later. If you wish
to use the text as a placeholder to change later, just enter some
placeholder text. When you are done, be sure to save your title and
exit the designer.
Adding Your New Title
Back in the vMix interface, click on Add Input and select title. When
the title menu comes up, you can easily find your new creation by
clicking on the Recent tab at the top. Once you select your title, you
will have the chance to replace your placeholder text by right clicking
it. Next, you can add that title to one of your overlay channels and
activate it to see how it looks with your output source.
This is just a basic look at the vMix GT Title Designer. There is no
limit to the ways you can create customized titles to go with your
productions.
Using vMix Call
With vMix call, you can invite guests from nearly anywhere to join
your live production. All your guest needs is a quality internet
connection, the latest version of Google Chrome and a webcam.
vMix takes care of everything else. You don’t need to worry about
extra equipment or common issues like echo or feedback. vMix Call
is available with the HD edition with one caller. 4K increases that to
4 callers, and up to eight are available with Pro.
Pro Tip 1: If you have a far end guest using vMix, try using a vMix to
vMix connection.
Pro Tip 2: vMix call provides you great quality and control for
remote guests. But you may want to consider connecting vMix with a
video meeting application like Zoom. This is explained in an
upcoming chapter in detail.

66
Getting Started with vMix Call
To get started, open your vMix interface and head to the input menu
in the lower left. Select Video Call at the bottom of the list. You will
see two options: Host a Call and Connect a Call. Connect a call
allows you to connect to another vMix production by sending your
vMix output. But, for now, try hosting a call.
Guest Connection Information
Next, you will see the password box with an automatically generated
password for your guest. Your guest can connect simply by going to
vmixcall.com and entering their name and that password. You can
also send your guest the link in the box below for a direct
connection. Just be sure the guest is using Google Chrome on their
computer.
Settings
Below that, you will see settings for the return feed. This will control
what you guest will see when they log onto the call. You can choose
the video source, but it will default to your primary video output
which is most likely what you will want your guest to see. If you have

67
the 4K or Pro editions of vMix, you can also choose to send any of
the three additional outputs.
Below that, you can choose the bandwidth of the video you send to
your guest. This defaults to 720p to 1200 kbps. However, if there are
any bandwidth limitations for you or your guest, reducing this will
not reduce the bandwidth of your production, just what your guest
sees.
Finally, you can choose what audio mix you want to send to your
guest. By default, you can send either the master audio or the mix for
your headphones. With both, mix-minus is automatically taken care
of, meaning your guest will not hear themselves echoing back
through the connection. You can also set up custom audio buses to
send audio to your guest. However, keep in mind, in those cases, you
will need to take care of your own mix-minus.
The box right below that allows you to choose only peer to peer
connections. Usually, there is an automatic fallback to a server if you
can connect directly to your guest. If you are trying to troubleshoot a
direct peer to peer connection, it may be useful to check this box.
Now, just click the OK button.
The Guest Interface
When your guest connects via the address and password you
provided, they will have a reasonably simple interface. It allows them
to control what they see and chat with the producer on the other end.

68
One final tip. You may want to go into the settings for your newly
created input and, under general, untick the “Automatically mix
audio” checkbox. That way, you can manually control your guest’s
audio and not have it automatically turn on or off as you move their
video into the output window.
Using the vMix Web Controller
The vMix Web Controller gives you access to many of the features
and controls of vMix from a smartphone, tablet, or any computer on
your network with a web browser. Just about any functioning
smartphone or tablet will work if it has a web browser and can
connect to the same network as your vMix computer. The Web
Controller gives you the option to control the live production while
away from the computer or give part of the production
responsibilities to another person. The vMix Web Controller is ideal
for remotely switching inputs, accessing shortcuts, updating titles,
and more.
Getting Started

69
To get started, go to Settings, and choose Web Controller. First,
ensure that the Enabled checkbox is ticked to activate this feature.
The Web Site Address shown in the “Web Controller” settings area
is what you need to access the controller. Copy and paste it into the
web browser of the computer you will be using. You can add
additional security by assigning a username and password. As long as
the password field is blank, no password will be required to log in. If
you enter a password, you can give specific access to devices. This is
helpful if you want to provide user access to only some features of
the controller.
The Interface
Once you enter the web address into the device’s browser and log in
if necessary, you will see four options represented by icons. Those
screens are shortcuts, controller, tally lights, and title editor.
Controller
The next icon, with four white squares, will open the controller page.
This gives you a fully functional switcher, just paired down for size.
Instead of full images and descriptions of the inputs, each input is
designated by number and a letter representing it. For example, a
camera on input 1 would be labeled C1, a title on input 2, T2. The
top 2 rows represent the Preview and Output windows. The green
square will represent what is live in the output window. A yellow

70
square represents what is currently in preview. Across the bottom of
the page, you will see all of the standard transitions. Tapping one of
those buttons will move the input from preview to output using the
selected transition. The next four rows represent the overlays, which
can be activated with just a touch.
Shortcuts
On the shortcuts screen, you will see all the shortcuts you created in
the shortcuts editor in vMix. If you wish to limit which shortcuts
show up on the web controller, you can tick or untick the Show in
Web Controller Box for each shortcut you create. The shortcuts will
behave the same way when activated from the web controller as they
would from the vMix computer interface.
Tally
The third screen is the tally light screen, which allows you to turn any
mobile device into a camera tally light to help talent know which
camera is live. By going to that screen and selecting a camera input,
the screen will light up yellow when that camera is in preview and
green when that camera goes live to the output.
Title Editor
The final page is the title editor. This enables on the fly editing of
titles that can update in real-time in vMix. You can select any titles

71
already set up in vMix and change the text. When the title is changed,
and the Update button is pressed, it will immediately change the title
even if it is in the live window. You can also add presets to quickly
switch between different text for that title input.

6 VMIX DEEP DIVE
vMix Color Correction Tools
A big part of making your live production look great is making sure
your colors look realistic and match from camera to camera. vMix
includes color correction tools that are advanced enough for color
optimization experts yet simple enough that average users can
improve their productions' overall look. Color correction tools are
available on every video input, including cameras, videos, and
images.
Basic Color Adjust Tools
Those who just wish to make basic color adjustments may be content
to work with the basic Colour Adjust tools. They can be accessed by
clicking the gear icon on the selected input and choosing Colour
Adjust. From this menu, you can adjust the black level, brightness,
transparency, and saturation. You can also independently adjust the
level of red, green, and blue. An auto white balance feature is also
available.

73
Pro Tip: Most cameras can look better with just a bit of Black
Stretch applied to their video feed from the “Colour Adjust” area of
vMix.
Advanced Color Correction

74
For more color control, select Colour Correction from the input
settings menu to access the professional color correction tools. The
interface offers control over the lift, gamma, and gain. The lift adjusts
the dark areas of the image, the gamma impacts the colors in between
black and white, and the gain adjusts the bright areas of the image.
The most basic function on this menu is the Basic Auto Correct
button that attempts to set the lift and gain controls to their optimum
setting. Also found on this page are several reset buttons shaped as a
circular arrow to undo any settings that you would like reverted to
default.
Color Wheels
The color correction tools inside vMix have three (3) wheels which
are used commonly in video editing software. The first wheel
represents the blacks (shadows) also called lift. The second wheel
represents Gamma or mid tones and the third wheel represents the
highlights and overall brightness of the image. Each wheel adjusts a
particular part of the image. The first wheel can be used to work with
dark areas, the middle wheel works on areas which are usually skin
tones and the final wheel is for the highlights. Using the three
components of the color correction wheels allows operators the
ability to do fine color correction in an intuitive layout. You can use
gain control, for example, to adjust the yellows just in the highlight of
an image.

75
Adjustment can be made on the color wheel by dragging the circle to
the desired location. Adjustments can be made to all colors equally by
using the Luminance/Brightness bar to the wheel's right. Hue and
saturation can be adjusted using the bar below the wheels.
Pro Tip: Try using the ON/OFF buttons to see the color
corrections you have applied. Sometimes it’s worth seeing all of the
changes you have made by looking back the original.
Color Bars
By clicking on Display Color Bars at the top, the view will be
changed to color bars here. The red, green, and blue levels can be
adjusted independently for lift, gamma, and gain. Color bars are
easier to operate then wheels because wheels are constantly adjusting
multiple colors with every change. Bars allow you to adjust a single
color independent of others. If you are just learning how to perform
color corrections or you are trying to fix a specific color issue, color
bars may be easier for you to operate than wheels.
What is a Vectorscope?

76
A Vectorscope is a tool that represents the color of your image. It is
an x and y graph representation of the color accuracy of your live
video feed. At the top of a Vectorscope you have red, toward the
bottom you have cyan and there is also a green. The Vectorscope
graph allows you to see the balance of the colors coming from your
live video. To accurately tune a camera, you can put up a color chart
in your space and zoom into it with your camera. The vMix color
chart will produce lines that connect your current image with the
ideal colors. A Vectorscope is a tool that is ideal for live video color
correction without having to rely on your own eyes and potentially
inaccurate monitor representations of an image. The Vectorscope is
all about color and provides you with tools to accurately adjust your
camera settings ideally on the camera side first. Once the camera has
been accurately tuned the finishing color corrections can be done in
vMix.
What is a Waveform Monitor?

77
For those with color correction experience or those who want to
learn, vMix also includes several types of Waveform Monitors. The
Waveform Monitor is the counterpart for the Vectorscope available
to handle brightness and exposure. With a Waveform Monitor, you
can easily see if your image is clipping at the top or if the blacks are
getting crushed. The Waveform Monitor will allow camera operators
the ability to adjust the image preferably in the camera first to ensure
your image has a good exposure.
Ideally, you want your camera’s image to be within the limits of your
Waveform Monitor. You can use vMix to make sure your video has
perfect whites and blacks using the tools as needed. The tool can be
accessed by clicking the small color bar box on the right side of the
video preview. Each of the waveform monitor options can be viewed
in a split-screen with a preview of the input or in a full screen
independently. These are essential for completing precise color
correction adjustments. Using the slide on the right, the zoom level
of the image can be adjusted. Users can make adjustments to the
color setting wheels and bars while seeing the precise impact on the
waveform monitors. This can often help even novices detect and
correct color issues.
Color Correction Presets

78
Another tool built into the vMix color correction system allows users
to save preset files that can be uploaded to other vMix inputs. This
preset information can be useful for color matching cameras from
different manufacturers. The preset will save your color correction
information which can be applied to any other input in vMix. These
presets may not get your image 100% corrected because every
camera's exposure will be slightly different.
Pro Tip: One of the key things with color corrections is starting with
exposure and color settings inside the camera. Many times the
highlights can be blown out before they even get into your video
production software. Using a Vectorscope and waveform monitor
you can bring down the range of your camera to make sure that you
are not clipping your sensor's full potential. These tools help you
make sure that you are not crushing the blacks or overexposing the
whites with the settings in your camera. The waveform monitor
specifically allows users to stretch the exposure to the perfect white
and black settings.
Input Video Preview Options

79
Underneath the color correction tools you will see the live video
preview of your input. On the right side of this interface you will see
options for changing this video to see the Waveform Monitor,
Vectorscope and various combinations that include a live video
preview. You can also apply video standard grids for SMPTE, square
and vertical video for monitoring.
How to use Virtual Sets in vMix
With built in virtual sets, vMix makes it possible to create a
professional looking set for your production with nothing more than
a green screen and some decent lighting. Virtual sets are easy to use
and they can look great. You can even have a custom virtual set built
specifically for your needs.
Getting Started
To start out, just make sure you have a green screen behind you or
whoever your talent is for the production. Green screens can be
purchased online in fixed and portable formats. You can even create
a permanent solution by painting a wall. You will need to get your
lighting right so that your talent and green screen are well lit. This will

80
allow the keying feature to remove the entire background
appropriately.
Color Key
The first step is to set up an input with the camera you wish to use
for the talent. Then, go into your camera input settings and choose
Color Key from the options on the left side. Use the eyedropper to
select a sample of the green screen. You can adjust the presets to get
it perfect or set one of the presets that will often give you excellent
results. Close out of that menu and you should now have a camera
input with your talent and no background. Now you are ready to add
a virtual set input.
Pro Tip: If your green screen does not cover the entire picture that
your camera is capturing, use the crop feature to remove unwanted
areas on the sides.
Adding a Virtual Set Input
Click on Add Input and select Virtual Set from the options on the
side. Now you get to choose your virtual set. Click OK and the
virtual set will show up in your inputs.
Customizing Your Set
Now it is time to start customizing. Next to your virtual set input you
will see your customization options. When you select “Camera” you
will have access to the various zoom options for your set. When you
click “Setup” you can access all the various layers in the set. Those

81
may include the backdrop, virtual screen, talent, and any other
customizable parts of your set that can be assigned to an input. Select
the layer and then assign the input you wish to use. For instance, for
the talent layer, you will want to assign the camera you just set up
with a green screen and color key.
With the layer selected, you can also customize the position of the
input in the set. For example, to get the talent in the right position,
just click and drag in the preview window and to resize just hold
down shift while dragging. Continue to assign layers and make
adjustments until you have completed all the features of the set you
want to use.
Once you understand how the virtual sets work, there are multiple set
options, the ability to create your own from scratch, and the option
to import custom sets from third-party sellers. You can also use the
export button at the bottom of the virtual set input to save all of your
settings to use the set later or import to another instance of vMix.
Note: The online course available on Udemy includes over 15
additional virtual sets that you can use for vMix. These virtual sets
have been designed for sales, marketing, houses of worship, finance,
and educational purposes.
Working with NDI Sources in vMix
NDI or Network Device Interface is a powerful way to share video
content across a local area network. The protocol, developed by
NewTek, opens new production possibilities, and with vMix, it is
easy to both send and receive video via NDI. Not only can vMix
share cameras, video, audio, and graphics to other vMix devices, it
can both send and receive from any devices or software that support
the NDI protocol.
NDI stands for Network Device Interface and it is a high quality,
video-over-IP standard developed by NewTek to enable video-
compatible products to communicate, deliver, and receive high-
definition video over a computer network ideal for live video
production.

82
What is NDI used for?
Many video projects use NDI to send and receive video over IP.
NDI features an auto-discovery feature which makes managing video
sources available on a network very easy. For example, a church may
use NDI to send PowerPoint slides from one computer and receive
them on another computer used for live streaming. Another example
would be setting up a display in an office to show an NDI source
coming from a video production software like OBS. Any Windows
or Mac computer can receive the NDI video stream and display it on
a TV located in a facility using free tools such as the NDI Studio
Monitor.
Adding the Source
First, be sure that your vMix computer and your NDI source are
connected to the same network. Adding an NDI source in vMix is
just as simple as adding any other source. Just go to Add Input and
select NDI/Desktop Capture. You will see all of the computers
and devices on your network that are connected via NDI. Under
each computer or device, you will see any available NDI sources. At
the bottom, you will see a few checkboxes. One will select only the

83
audio from the source. The other will receive the source in low
bandwidth mode. Just click on a source to add it as an input. Once
you have the input setup, you can change it to another NDI source
by just right clicking on the input and selecting a new source.
Using the NDI Source
Once the source is ready, you can use it just as you would any other
video input. You can toggle the audio on and off, preview it, or send
it to an overlay channel. By clicking on the gear icon, you can access
the full settings menu. When you open the settings, you will see that
the NDI source settings are very similar to the settings on a directly
connected camera and can be adjusted the same way. You can change
the name for easier reference, set the mouse click behavior, mirror it,
sharpen it, and enable or disable the automatic audio mix. You also
have access to color correction and the ability to set up a chroma key
if the source is set up with a green screen. You can make position
adjustments, add it to a multiview, and even set up triggers and tally
lights.
Pro Tip: Unlike normal inputs, you can right click inputs to open up
additional options.
Bandwidth Matters
One important thing to consider with NDI is network bandwidth.
While NDI sources are local and do not require internet bandwidth,
they still need sufficient internal network bandwidth. For the best
results, be sure you are using a gigabit network.
Note: NDI stands for “Network Device Interface” and NDI® HX
is the “High Efficiency” lower bandwidth version of NDI. NDI HB
stands for the “High Bandwidth” version of NDI. NDI features a
combination of high-quality video with low latency transmission that
is ideal for live video production. NDI|HX is ideal for broadcast
professionals adding NDI sources to an existing network that has not
been originally designed for video production. NDI|HX video
sources are generally one tenth of the bandwidth of full NDI sources.
See the bandwidth comparison chart.

84
NDI Mode Bandwidth
HDI HX Low (720p60fps) 6-8 Mbps
NDI|HX Medium (1080p30fps) 8-12 Mbps
NDI|HX High (1080p60fps) 12-20 Mbps
NDI|HB (1080p60fps) 125-200 Mbps (Nominal Range)

Tip: Network Bandwidth head room recommendations can vary
widely from 30% - 60% depending on what the network is utilized
for. Please consult your network administrator before adding NDI
sources to your local area network. Newtek suggests “NDI traffic
should not take up more than 75% of the bandwidth of any network
link.”.
Sending NDI from vMix
Keep in mind that it is also simple to send NDI across your network
from inside vMix. Just go to your Settings menu and select Output.
You can then easily assign any of your output to send an NDI signal
from your Output, Preview, MultiView, or any input source.
What is an NDI Camera?
NDI cameras are able to communicate using the Network Device
Interface or NDI protocol. They can connect to a LAN (Local Area
Network) and seamlessly integrate with hundreds of software

86
applications including OBS, Wirecast, vMix, xSplit, NDI Studio
Monitor and much more.
What is an NDI camera used for?
NDI cameras often have PTZ (Pan, Tilt and Zoom) functionality
which takes advantage of the two-way communication capabilities of
NDI. In this way, NDI cameras can be controlled over the same
single ethernet cable used to send audio and video. For example, a
PTZOptics NDI camera can use a single ethernet cable to power the
camera, control the PTZ functionality of the camera, and to send
audio and video to a source on the network. PTZ camera controls
inside of vMix will be reviewed in an upcoming chapter.
What is the difference between NDI and SDI?
SDI is a technology that has been around for decades. SDI stands for
Serial Digital Interface, and the cable itself is capable of sending
uncompressed video long distances. NDI is a much newer
technology that uses the latest video compression methods to make
sending and receiving high-quality video possible over standard
computer networks. An SDI camera video feed can be converted
into an NDI stream and sent over the network. An NDI video feed
can also be converted into an SDI video output and plugged into a
monitor.
How do I set up an NDI camera?
Most NDI cameras are plug and play when it comes to setup. NDI
cameras can be plugged into any LAN (Local Area Network) and
configured to operate with any software or hardware solution that
supports NDI. Once an NDI camera is plugged into the network, it
will show up as an available source on your network; therefore, the
friendly NDI name that you give your camera will show up in any
software or hardware solution when you click the “add NDI source”
option.
How can I capture video from another computer?

87
Perhaps one of the most popular ways to get started with NDI is
sending video from one computer to another. Popular examples of
this include sending PowerPoint slides from one computer on your
local area network to the main vMix video production software. vMix
has a handy tool called vMix Desktop Capture that you can
download for free to enable a secondary Windows computers to send
video via NDI back to your main vMix computer.
vMix Desktop Capture for NDI is incredibly easy to use. Once you
open it up, it will search your computer for potential screens and
applications to capture and it makes them available on your local area
network via NDI. Back at your main vMix computer you will
instantly see all of the available screens and windows available to
connect with via NDI using the vMix Desktop Capture for NDI
tool.

88
There are just a few options that are revealed when you click the
Settings button. vMix Desktop Capture for NDI allows you to show
or hide the mouse cursor. You have the option send loopback audio,
choose silence or a specific audio interface. You can also minimize
this application at start up and enable GPU acceleration. It is that
easy to use!

89
PTZ Camera Controls in vMix
vMix has modernized live video production and increased what small
video production teams are able to do. vMix 4K and Pro editions
include multiple ways to control pan, tilt and zoom cameras which
can help automate video production workflows even further. vMix
can currently control specific PTZ cameras over an IP connection
and USB cameras that support UVC.
Here is the list of PTZ cameras that vMix currently supports:
1. Sony
2. Panasonic
3. PTZOptics
4. iSmart
5. HuddleCamHD (via USB)
Enabling PTZ Controls
You can enable PTZ camera controls inside of vMix by opening an
input and clicking on the PTZ tab. Here you can select one of the
supported devices in the dropdown menu. Most PTZ cameras will
require a static IP address for vMix to connect. USB cameras like the

90
HuddleCamHD Pro can be controlled via a USB connection by
selecting the UVC PTZ option.
Ethernet Controls
To gain IP controls of any IP supported camera you must make sure
your computer is connected to the same network as your PTZ
camera. You will also need to know your camera's IP address.
PTZOptics cameras for example can receive an IP address in two
ways. One is a statically assigned IP address, where you manually give
the camera an IP address on your network. The other way is via
DHCP. DHCP allows your camera to automatically receive an IP
address from your network’s router.
Pro Tip: Your camera and computer should be on the same IP
range. You can find the IP address of your computer using the
Command Prompt in Windows and typing in “ipconfig” and
pressing Enter. Look for your computers IPv4 address. Make sure
your camera’s IP address is on the same IP range which means the
first 3 sets of numbers are the same, and the last number is unique.

91
Click Add Input and select Camera. If you have an NDI camera
click NDI and choose your camera from the list. Select your camera
from the list and click OK. Once your camera is inside of vMix you
can click the settings cog to find the PTZ section. Inside the PTZ
section you will see a device type dropdown menu.
Note: ZCam camera models from PTZOptics do not offer pan and
tilt but vMix can control presets and zoom.
Once you select your camera's control method, you can enter your
camera's IP address and press connect. This you will unlock the pan,
tilt and zoom controls of your PTZ camera. You will notice two
control bars which allow you to select the speed of your pan, tilt and
zoom. There is also a slider designated to control the speed at which
the camera moves in-between presets. This is ideal for adjusting the
camera to perform slow moving scenes that sweep across an area, or
quick movements that are hidden from viewers while the camera is in
preview.
You should also notice a Create Input at this Position button at
the top right of the input settings window. You can click this button
to create a PTZ preset inside of vMix. When you click this button
vMix will create a new input inside of your vMix production. When
you bring this input into preview the camera will automatically recall
the camera’s PTZ preset position.
You will notice that vMix takes a screenshot of the camera's position
when saving the preset inside of vMix. In this way you recall PTZ
presets with a visual aid that is inside each thumbnail. The idea for
professional productions is that when you use one of the PTZ
presets in the preview window the location of the PTZ preset moves.
In this way, you can hide the PTZ movements from your audience if
you would like to.
It is worth noting that PTZ camera controls are also available inside
vMix shortcuts. Therefore, you can control PTZ cameras using a
variety of hardware solutions that integrate with vMix. For example.
you can use an Elgato StreamDeck, an Xkeys controller, or even a
USB connected xBox controller.

92
UVC Controls
UVC controls allow you to control webcams that support UVC. To
use this PTZ method, simply bring your camera into vMix using the
camera input via USB. Then inside of the settings window, in the
PTZ section choose UVC PTZ and click connect. Wow. It’s that
easy. Now you can operate PTZ camera control functions inside of
any PTZOptics or HuddleCamHD connected USB camera. UVC
controls are limited in comparison to network connected PTZ
cameras but they are easier to connect with plug and play USB
cabling. The HuddleCamHD Pro is an interesting camera that was
designed to be used like this. USB cameras with high resolutions
sensors like the 4K HuddleCamHD Pro can be used with UVC or
virtual PTZ options inside of vMix very effectively.
Digital PTZ controls

93
Finally, vMix features virtual PTZ options. High resolution cameras
like the HuddleCamHD Pro allow you to digital zoom in using 720p
or 1080p productions without loss of quality. You can also use
cameras with 4K Blackmagic capture cards to bring the video into
vMix and operate with digital PTZ controls.
Once this input is inside of vMix, in the settings window, in the PTZ
tab, you can select Virtual PTZ and choose a Zoom Limit. Once
you press connect you can now operate the digital pan, tilt and zoom
inside of vMix with the set Zoom Limit. You can set presets and
operate the input like a real PTZ camera.
Pro Tip: Try the merge function between two digital presets. It
almost looks like a real PTZ camera! Digital PTZ controls can be
added to almost any input.
External Output (Connecting vMix with Zoom)
Seemingly overnight, Zoom became the go to video conferencing
platform for businesses, non-profits, government agencies, and
schools. While Zoom is a powerful product in its own right, users
quickly began to look for ways to integrate other video tools. One of

94
those tools is vMix. Users want to be able to feed the live video
produced in vMix to the Zoom software and integrate the video from
Zoom into their live video production in vMix. Fortunately, thanks
to the power and flexibility of vMix, this is not a problem.
There are multiple ways to do this, but the simplest method is to
simply use vMix to output video directly into Zoom using the virtual
vMix webcam and the External button. It’s a little bit complicated
but it’s extremely powerful.
Here are two ways to connect vMix with Zoom.
1. Use a single computer with dual monitors. Capture the video
with a desktop capture and the audio with virtual audio
cables.
2. Use NDI with a second computer. Use the NDI virtual input
to handle transferring audio and video over your network.
Both methods require Virtual Audio Cables that you can purchase
and install here - https://vb-audio.com/Cable/. VB-Audio provides
virtual audio cable drivers that you will need to install on your
Windows computer in order to virtually send audio to and from
Zoom. You can download and install these cables fairly easily and the
following tutorials will assume that you have these drivers installed
and ready to use.
Method #1

95
In the included diagram you can see how to connect vMix and Zoom
with a single computer. You can start by launching a Zoom meeting
and opening it up on a second monitor connected to your computer.
This method will require a second monitor. On Monitor #1 you
should have vMix open. On Monitor #2 you should start a Zoom
meeting. You can start by adding an input into vMix for the Desktop
Capture of your Zoom Meeting.
Pro Tip: Inside of Zoom you can navigate to the settings area under
accessibility to turn hide the meeting control bar.
Once you have an input inside of vMix to capture the video from
your Zoom Meeting you can turn on the External button in vMix.
This button will enable your virtual webcam which you can select
inside of Zoom. It should appear as an option called “vMix Video”
when you click the up arrow inside of Zoom to select your camera

96
source. This video is the “return video” which you can send to your
guests of the vMix video production.
Next you will want to set up the audio so that it can flow naturally
from Zoom and vMix. To do this, you will need to enable a second
audio bus in vMix under the Audio Outputs area.

97
In the Audio Outputs area, select Virtual Audio Cable A as your
“A” output bus. When you do this an entire audio output bus is
created inside of vMix which will show up in your audio mixer. You
will also see a little A button that is selectable for every audio source
in vMix. By clicking this button on specific audio inputs, you can
select which audio you would like to send via the bus. In this case,
you will select your microphone and any other audio sources you
want guests in Zoom to be able to hear.
Pro Tip: If you play a video during your vMix production and you
want your guests to hear it in Zoom, do not forget to click the A
button in the audio mixer for that video.
Now that you have your vMix audio output setup, you can complete
this tutorial by selecting your virtual audio cables inside of Zoom.
For the Microphone, select virtual audio CABLE A. For the
Speaker, select virtual audio CABLE B. Essentially you are telling
Zoom that your microphone is anything you send through your vMix
audio bus. You are also telling Zoom to send all audio that would
come to your speakers into a virtual audio cable that you can bring
into Zoom.
Finally, you can add an audio input inside of vMix which is CABLE
B. This will allow you do capture all of the audio coming from Zoom
into vMix.

98
Pro Tip #1: Now that you have audio from Zoom in vMix you can
enhance that audio with professional VST3 plugins.
Pro Tip #2: You may want to distribute audio from vMix into a
space where people can hear it. It could be a wireless headset for
your on-screen talent, or it could be an amplifier and speakers for a
large space.
The explanation below shows you how to use two computers on the
same network and sharing the audio and video via NewTek's NDI

99
protocol. This is a great introduction to the power of NDI and it’s
use for video production.
Here is another way to connect vMix with Zoom:
• A separate PC laptop or desktop connected to the same
network as your vMix computer.
• The vMix Desktop Capture program available at
https://www.vmix.com/software/download.aspx#download
desktopcapture running on the second computer
• The Virtual Input program in the Newtek NDI Tools Pack:
https://ndi.tv/tools/ running on the second computer.
Here is how to set it up:
1. In the vMix settings menu, choose the Outputs/NDI tab and
turn on the NDI button next to Output 1.
2. Click on the gear icon next to that output and select Bus A
from the Audio Channels dropdown.
3. Go to the audio outputs tab in settings and change the Bus A
setting to enabled.
4. Go to the audio mixer. Activate the Bus A button for any
audio inputs you want to be sent to Zoom. If you are going
to share your entire live production, that would likely be all
your used audio input sources.
5. On the other PC, open the NewTekNDI Virtual Input
software you downloaded as part of the NDI tools pack. To
get to the options, click on the up arrow inyour Windows
task tray's bottom right and look for the yellow NDI icon.
Click on it. Click on the name of the main vMix computer
and then select Output 1.
6. Open Zoom on your second computer and start your
meeting.
7. Click on the up arrow next to the microphone in the lower-
left corner and select, as your microphone Line (NewTek
NDI Audio)
8. Click on the up arrow next to the video camera and select
Newtek NDI Video as your camera.
9. Run the Desktop Capture software on the second computer.

100
10. To bring Zoom into vMix, use the Add Input button and
select the NDI/Desktop Capture option. Choose NDI,
locate, and click on the computer and display where Zoom is
currently showing.
You are ready to go! One quick warning: Be sure not to accidentally
enable the Bus A audio button on your desktop capture input.
Otherwise, your guest will hear an echo.
Using vMix Playlists
A great way to automate your productions in vMix is by using the
playlist feature. This feature allows you to create a playlist of inputs
and automatically transition between camera, videos, and other inputs
you have created.
Getting Started
Once you have your input sources set up in vMix, click on the gear
icon next to the PlayList button at the bottom of the interface. This
will bring up the PlayList dialog box. Click New PlayList and give

101
it a name. If you have an existing playlist that you would like to work
from, you can check the Copy Current PlayList box. Once you have
multiple playlists, you can select the one you want to work with from
the dropdown menu in the dialog box's upper right corner. Keep in
mind that playlists are connected to presets. So, if you want to save
your playlists, be sure to save your preset.
Adding to the PlayList
Adding inputs to the playlist is as simple as clicking on the available
inputs in the left window and then clicking the right arrow. Remove
them from the playlist by clicking on the input in the right window
and click the left arrow. Once you have multiple inputs on the
playlist, you can select any one of them and move them up and down
in the list.
Adjusting Input Settings
Once you have added your playlist items, you can click on them to
adjust their individual settings. This will open another dialog box. For
videos, you can set the starting position to the point in the video you
want it to begin. You can also set the duration. For videos, this would
set how long the video would play after the starting point. For
cameras or other sources, this determines how long the playlist will

102
stay on this input before moving to the next item. You can set the
transition type to any of the available vMix transitions and set that
transition length. Finally, the display type will determine whether the
input will be shown in full screen or assigned to one of the pre-
configured overlay channels. Now we can click OK and repeat this
process for each of our inputs.
Pro Tip: If you choose inputs with PTZ camera presets, you can
effectively automatic PTZ camera operations. In this way, you can
have cameras move to various locations with PTZ presets that are
called in a looping playlist.
Changing PlayList Settings
When you are done configuring our inputs, we have a few more
options in the PlayList dialog box. At the bottom, you can choose if
you want the playlist to loop. Ticking the Begin from Selected item
box will begin the playlist from any selected input instead of from the
beginning of the list. Clear overlays will clear any overlays on the
inputs between transitions. Finally, manual mode will keep the
playlist from advancing from input to input instead only advancing
when the previous and next buttons are pressed. When you are done,
click close.
Starting the Playlist
To start the playlist, just click on the PlayList button at the bottom of
the interface. If you want the option of making adjustments or
manually advancing the playlist, you can simply click the gear icon
again to reopen the PlayList dialog box.
Working with vMix Data Sources
vMix offers several options to add dynamic content to your live
productions. One of them is vMix Data Sources. With Data Sources,
you can import data from sources like spreadsheets, RSS, JSON, a
text file, and XML. Even better, this data can be updated in real-time
to your live production.

103
Getting Started
To get started, find the hamburger icon on the lower right of the
vMix interface and click on Data Sources Manager. Clicking on the
plus icon in the upper left corner of the dialog box will reveal the
different data sources you can use in vMix. Clicking on a source type
will open up a dialog box with the information for that source. For
local files like Excel or CSV spreadsheets or text files, you will have
the opportunity to browse for the file on your computer or network.
For online sources, the dialog box will ask for a URL and any other
information necessary for access.
Once you have selected your data source, entered the necessary
information, and click OK, the onscreen table will begin to populate.
With data in your table you can assign that data to a title to bring it
into our production.
One great example for using Data Sources is Google Sheets. You can
have someone manage a Google Sheet table with various fields of
data that you need updated. You can then integrate Data Sources
with Google Sheets and pull that data directly into your vMix titles.
Adding a Title Input for Your Data

104
Go to Add Input and select Title from the list on the left. Choose
Title from the tabs across the top and select a title that works for
your information. Optionally you can create custom titles using the
GT Title Editor. Then click OK. This will bring up another dialog
box where you can link your data to this title. In a simple title, there
will be fields for headline and description. Starting with the headline,
click on Data Source at the top of the box. In this dialog box,
choose the type of data source you are using. If you have already set
it up in the data source manager, the table name will be brought in
automatically.
Depending on the type of data you are using, you may want to leave
the column and row settings as they are or customize them for your
needs. By default, this will initially pull the first column and row.
When you are done, click OK. You can choose which row of data
you would like your titles to use via Data Sources by clicking on the
row. You can also choose to have the data loop through the rows.
Now go and do the same for the description. Leave the column on
auto if you want the second column to appear since the first was used
for the headline. You can also manually select the column you wish
to use. When you are done, click OK.
Formatting Your Title
Your title will now appear in the input section. You can click on it to
see it in the preview window with your data. With the title editor still
open, you can make format changes to the text in your title. Using
the buttons at the top, you can change the font and adjust the size
and color.
Additional Settings
There are a couple more settings within the data sources manager
that will impact the data's behavior on your title input. Go back to
the data sources manager. At the bottom of that box on the left is a
button for Auto Next. Click this and set the time if you would like it
to move down the rows at set intervals updating the data. You can
also set it to loop if you would like it to start over when it is done.

105
On the bottom right, you can select the update interval. This is useful
if the data from your source is being regularly updated. For instance,
if someone is entering new data into the spreadsheet you are
accessing, this number will determine how often it checks for
changes.

106
7 MASTERING VMIX
vMix Instant Replay
The vMix instant replay system is quite powerful, and it is available
for one camera in the 4K version and 4 cameras in the Pro version.
The instant replay system essentially records video from cameras to
the hard drive so that the video footage is available for replay
instantly. vMix’s instant replay system also supports slow motion
playback which is ideal for high frame rate cameras.
The vMix instant replay system works best when recording at 100
Mbps on a solid-state hard drive. That is 100 megabits per second for
each camera. So be very careful not to record instant replay video
footage for too long or you will run out of hard drive space quickly.
If you plan on using your instant replay footage in slow motion,
frame rate becomes very important to preserve the quality of your
replay video. For example, if you broadcast in 1920x1080p video
resolution at 30 frames per second, your main live stream being
broadcast has 30fps. If you set your cameras and instant replay

107
system for 60 frames per second you can slow the video down by
50% and still deliver smooth 30 frames of video for your live
broadcast. vMix also allows you to slow down the audio included in
your instant replay.
Here are some considerations for vMix instant replay:
1. All cameras must have the same resolution and frame rate
when you have a multi-camera instant replay instance.
2. vMix Instant Replay seems to work best set to 100
Mbps.
3. vMix will calculate how much recording time you will
have depending on the number of cameras you are using
in instant replay
4. You always need to mark in and out segments for your
instant replay system
5. To recall an instant replay that was recorded simply
double-click the event you have created.
6. Your instant replay is essentially a regular input in vMix
so you can transition to that input like any other input
If you are a vMix user and you have never used instant replay, it will
open your eyes to all new kinds of live streaming possibilities. Here is

108
a complete list of vMix Replay features that come directly from
vMix.
• Four channel continuous recording of up to four camera
inputs including audio.
• Recordings are industry standard MPEG-2 I-Frame MPG
files at up to full HD 1080 with Progressive and
Interlaced support.
• Audio is recorded as uncompressed 48khz 16 bit stereo
PCM
• Two channel simultaneous playback of recorded footage
with dynamic camera angle switching.
• Precise slow motion playback control from 10 to 100%.
• Reverse playback and frame by frame control.
• Four Events lists are available that can each include an
unlimited number of Mark In and Mark Out points that
can be added on the fly and changed at any time.
• Each event can have a default camera angle selected for
playback and text comments can also be included with
each angle for easy recall.
• Easily playback entire Events lists or selected entries as a
highlight reel, complete with transition effects and
background music.
• Auto mark in / out controls allow quick event creation
with the click of a button with 5, 10 and 20 second
presets.
• Keyboard shortcut support for all replay functions
• Many hardware control options available including Scroll
Wheel slow motion control and Contour ShuttlePro
support.
• Export events to separate video files on the fly, or use the
recordings straight away in your favorite video editor
without conversion.
• Use vMix Replay as a dedicated instant replay system or
incorporate it into your existing vMix based production.

109
How to use vMix Triggers
vMix Triggers can add powerful automation sequences to your live
productions. This becomes especially important for complex
productions with a single operator. The producer will not need to
remember every single cue and function since many can be
automated through triggers.
Triggers can handle anything from adding overlays after a transition
to multiple-step processes that will run much of a live show for you.
Some examples of common uses include a trigger that starts
recording and turns on the microphones at the end of a countdown
sequence. Another could be used for switching to the primary camera
when a video ends. There is really no limit to what you can automate
with triggers.
Triggers are very similar to shortcuts. They both start with a function.
With a trigger, it is the press of a key or button that begins the
function. With a trigger, the function is started automatically when
some condition is met. Shortcuts and triggers can be used together
with a shortcut starting a sequence that continues automatically
through triggers.

110
Setting Up a Trigger
Setting up a trigger in vMix is straightforward, and it is done through
the input settings. Select the input you would like to work within the
input section and click on the gear icon in on the lower right. Once
the settings menu for that input is open, click on Triggers on the left
column. If you have any triggers already set up, they will be listed
here.
Under the trigger list are the fields for setting up a new trigger. The
first column is the actual trigger which is the event that starts the
process. If you click the dropdown menu, you will see that triggers
can include OnCompletion, OnTransitionIn, OnTransitionOut,
OnOverlayIn, OnOverlayOut, OnCountDownCompleted, and three
audio triggers.
OnCompletion is perfect for triggering a function when something,
like a video, is finished. The transition triggers are based on fading or
cutting to an input. The overlay triggers work when an overlay is
activated or turned off. With the countdown trigger, you can attach a
function to the completion of one of the built-in countdown timers.
The audio triggers are relatively basic and can trigger a function when
an input audio source crosses a dB threshold.
The second column lets you set the function that will occur for that
input when the trigger occurs. You can choose from hundreds of

111
functions by clicking on the dropdown menu and selecting the
category on the left side. In the next column, you can choose the
source used for the function. For instance, if the trigger is set to
transition from your input source, this is where you would choose
what it should transition to. If you are using any sort of transition
function, the next column lets you set the duration. The next column
allows you to set the delay before the function takes place.
You can set up multiple triggers on each input and easily change the
order in which you wish them to happen.
There is one crucial thing to keep in mind if you are using MultiView
of layered inputs. Even if triggers have been enabled, they will only
work on the primary layer. That means if you create an input with
triggers and then include that input in a MultiView input, those
triggers will not function. You will need to add triggers to the
MultiView input itself.
vMix API for Developers
vMix is a powerful live video production software platform with
functions and features for nearly every need and an intuitive graphical
user interface. However, vMix also allows developers to make the
software even more powerful by using their API (Application
Program Interface.) An API enables developers to create ways to take
advantage of the software's functionality from outside of the standard
user interface. This creates limitless opportunities for ways of using
the software even beyond the ways the original developers intended.
APIs can potentially connect vMix to other software, hardware, or
interfaces.
Discovering Possibilities
If you are a developer, it may create an interest in developing new
applications or tools. For vMix users, it may move them to learn the
requisite skills or partner with a developer to bring some new ideas to
life.
The Interface in Action

112
vMix provides two different interfaces for developers, custom
XAML, and API, which we refer to here. With the vMix HTTP Web
API, many of the software's functions can be controlled by sending a
simple command over the network. It is so simple that you can see it
in action. Go into your vMix software settings and go to the Web
Controller menu. Copy the Website address for the controller. Open
a web browser on another computer connected to the same network
and enter that address, plus the following:
/api/?Function=Fade&Duration=1000.
So, for instance, if my web controller website address was
http://192.168.0.128:8088, I would enter
http://192.168.0.128:8088/api/?Function=Fade&Duration=1000
into the address bar of my web browser and hit enter. If you entered
everything correctly, you should see whatever is in your vMix preview
window, move to the output window with a one-second fade.
Available Functions
Most users will not access these commands through a web browser,
but the effect is the same. The web API call can access any of the
functions available through the Shortcuts feature in vMix. You can
see that list by going into the vMix settings menu, selecting Shortcuts,
adding a new shortcut, and clicking on the Function field's dropdown
menu. They are sorted into categories.
That function needs to be specified in the API call along with any
necessary parameters, including duration, input source, text for titles,
or other values. The necessary parameters can be found, again, in the
add shortcut dialog box in the settings menu. If the function is
successfully carried out, it will return a standard response code.
Once you understand the basic framework of the vMix API, all it
takes is an understanding of using developing a program, app, or
applet to communicate with vMix. Information on that type of
programming is available on the web, or you can find a developer
with experience with APIs.

8 AN AMAZING CASE STUDY
How the Griswold High School Uses vMix to Produce the
Morning Announcements
The Griswold High School morning announcements show manages
to involve over 10 real-time student-run operational roles using vMix
and an IP connected workflow. Throughout the production of their
morning announcements show, the club is using vMix in multiple
ways separate computers. Leveraging the school’s local area network
(LAN), the club is able to connect four computers together into a
single cohesive video production environment. Each computer
provides an individual student access to the main vMix system and it
allows students to interact with each other and share resources.
The graphic above illustrates the major parts of the video
production system. The main computer is running vMix and is
controlled by the technical director using a keyboard and mouse. This
computer has three camera sources and the audio mixer connected to
it. The second computer is used to display the weathers man’s slides
for the day. Using a camera with a green screen, the main vMix

114
computer can chroma key the weather man’s background and put
him in front of his PowerPoint slides. In this way, the school can
present the weather just like you see on TV and the weatherman can
control his slides with a wireless PowerPoint remote control that is
used to advance the slides.
This laptop is running a software called the vMix Desktop
Capture which is able to send the video directly from the laptop into
the main vMix computer for the technical director to use over the
network. You can see a “Confidence” monitors is in place to show
the weatherman what he looks like on camera with his PowerPoint
slides behind him. This allows the weatherman to see exactly what he
is talking about while remaining focused on his delivery to the
camera.
A third computer is used as a character generator. This
computer uses the vMix Web Controller to allow the graphics chief
to update titles inside vMix and overlay graphics directly onto the
broadcast when they are needed using shortcuts.
The vMix web interface has 4 different areas: shortcuts,
controller, tally lights, and titles. These can be changed by clicking the
icons along the top. For the graphics chief, they are only concerned
with titles and shortcuts. The graphics chief can open two google

115
chrome web-browsers and split the screen 50/50 to have access to
both at the same time. On the titles screen, the graphics chief will see
all the titles that are currently in the vMix production on the main
computer. From here the operator can quickly edit and change these
titles before they are shown on screen.
The shortcuts screen will automatically show all shortcuts
that have been set up on the main vMix machine. A shortcut is a
trigger that can be designed to perform almost any video production
task in the software. This allows the club to give the graphics chief
access to specific buttons that can trigger almost any action including
fading to the opening video, overlaying graphics, and initiating the
closing credits. In the picture above, you can see the shortcut buttons
available on the left-hand side of the screen. These include opening,
birthdays, lower third, credits, and word of the day.
The word of the day is an interesting portion of the show
where the club leverages website data to produce up to date
information each day. The club uses vMix’s “Web Browser” input to
display this information by entering in the address to the
Dictionary.com’s word of the day website
(https://www.dictionary.com/wordoftheday). Because this webpage
is updated every day, the input will always have a new word displayed

116
in its title each day. So, when it comes time to display the word of the
day, the graphics chief only needs to click the shortcut button that
has been configured to overlay a cropped portion of this webpage
onto the screen. The teleprompter chief will check this word and
make sure it is included in the script for the on-air talent. The on-air
talent will, in turn, make sure they understand the correct
pronunciation before the show.
The school birthday title is a ticker that can be updated with
information that scrolls across the bottom of the screen. Tickers are
used quite commonly in television production to provide additional
information in a non-obtrusive way. The graphics chief can quickly
update this information inside the titles section of their web
controller. If there is a birthday that they need to display in this
ticker, they can use the shortcut button to trigger the overlay on and
off the broadcast as needed.
Inside vMix, each camera input looks like a square. Each
square has a number which corresponds to its position in the
production. When the technical director clicks one of these squares,
that input is put into the preview window by default. This preview
window is the area that the technical director uses to queue up the
next upcoming video input for the production.

117
Using Multiview layers the technical director can have a single
input setup with multiple layers attached by default into a new
composition. The broadcast club does this nicely with the
weatherman input. This input is essentially two inputs layered
together into one. Using this method, the technical director has just
one input to transition to that is built out of the weatherman
PowerPoint slides with the chroma keyed video layered on top.
Other important buttons that you will learn about in our online
course include the record button, the stream button, and the
fullscreen button.
The technical director has a total of 15 inputs inside vMix.
The graphics chief controls five of these inputs and the other 10 have
been organized into a production workflow for morning
announcements. Here are the inputs:
1-4: Camera placeholders (makes shortcuts easier to manage)
5-7: Camera inputs (HDMI internal card, external dual HDMI
capture)
8: Opening graphics (Graphics Chief)
9: Virtual camera input with chroma key enabled
10: Credits (Graphics Chief)
11: Birthday Ticker (Graphics Chief)
12: Lower Third (Graphics Chief)
13: NDI in from Weatherman PowerPoint Slides (Weather)
14: Web Browser - (input from dictionary.com cropped for word of
the day) (Graphics Chief)
15: Audio Line In
It is really quite incredible what can be done with this type of
network connected video production software. This level of video
production quality used to cost hundreds of thousands of dollars and
therefore was out of reach of most broadcast clubs. Most traditional
video production switchers have a centralized control system. This
type of centralized control has traditionally made it difficult to have
multiple people working together using standard computers. Now
school broadcast clubs can build out systems that can integrate teams

118
of students with independent roles working together on a single
broadcast simultaneously.

119
9 CONCLUSION
Over the years, vMix has made many significant steps to improve
their software for the users they support. I have had the privilege to
meet up with the creators each year at the NAB Show (National
Association of Broadcasters) in Las Vegas, Nevada. I have seen
firsthand, that vMix consistently in listens to their customers to create
a product that is truly designed for modern live video producers.
Each major new release has built upon the last adding new
breakthrough features such as NDI support, vMix Call, Color
Correction, SRT and so much more. While no Macintosh version of
vMix exists, for those using Windows computers, you will be hard
pressed to find a more robust solution for video production.
A lot can be said about choosing a video production software that
you grow into. There is a significant learning curve users face when
they start using a new software solution. Hours of time are spent
learning a new interface which can be wasted if you eventually
outgrow the feature set available on the software you started learning
on. Many users who start with the free OBS (Open Broadcaster

120
Software) solution eventually find themselves upgrading to vMix in
order to gain the features they need to complete their video
production projects.
Luckily, vMix allows users to try the software for free for 60 days.
Not only that, but vMix offers tiers of price points that make it easy
for organizations to upgrade and find the solution that fits their
budget.
Finally, I would like to express how important vMix has been for my
own career. As a video production professional, I use vMix more
often than Adobe Photoshop, Premiere, or any other primary video
software tool I have access to. I even use vMix in combination with
Zoom to spice up my meetings and host private webinars where I
can switch between multiple cameras with ease.
It has taken many years for me to become proficient in vMix. It is my
hope that this book will speed along the learning process for aspiring
video professionals around the world.
