This document outlines the agenda and key points from Lecture #5 of a video production course. It discusses critiquing student videos, reviewing sound fundamentals like microphones, frequency, amplitude, and decibels. It also covers pickup patterns of microphones, types of microphones like handheld, lavalier, and shotgun. Tips are provided for ensuring good sound quality including using meters and avoiding overmodulation. The next assignment is introduced where students will work in groups to create a promotional video for a local business.
Lecture 5
- 1. TCOM 4170 Spring 2014 Video Production Amani Channel, MA Lecture #5
- 2. Agenda Video Critique Review Sound Next Assignment
- 3. Critique 1. Did you finish the video? 2. Did you upload it toYouTube? 3. Did you create a blog post and embed the video? 4. Did you turn in the proposal and script? 5. How was the story crafted? 6. Could this be aired onTV? 7. How was the framing, audio, editing?
- 4. Remember • Goal is to create interesting stories • Tell narratives • Learn professional video production techniques • Composition • Lighting • Audio • Editing
- 5. Audio (Chapter 10TFH) With video, good sound is just as if not more important than video Microphone: Equipment that turns sound into an electromagnetic signal Sound waves:Vibrations that travel through air Crest: maximum air pressure - trough: release Frequency: Number of cycles that the sound wave travels in one second Pitch: high/low Amplitude: Height of the wave Decibel: How amplitude is measured
- 6. Sound Need to know what kind of speech, instrument, or situation that you’re capturing Transducer:Transduction - converting sound Two main kinds of mics: Dynamic/Condenser Dynamic: Durable, no battery Condenser: More sensitive/phantom power/battery Ribbon: (sometimes called dynamic)
- 7. Pick Up Patterns Mics hear sound differently pp. 391 Omnidirectional, bidirectional, unidirectional (cardiod) Omni – Picks up sound from every direction Bi – Picks up sound from two opposite directions Uni – Heart shaped-narrow range of sound
- 8. Types of Mics Handheld: Good for run and gun, need to move the mic – a bit obtrusive. Condenser/or dynamic Lavaliere: (Personal) Clip/lapel – condenser – good for sit down interviews – hands free Shotgun: Long mics (look like a gun) – captures sound from a distance (1-15 feet). Usually condenser
- 9. Sound Quality VU/LED meters: Measures sound wave voltage Peak 0dB = 100% (above that audio will distort) Overmodulation: distortion Recording clean sound Monitor with headphones Test record Patience
- 10. Sound Quality VU/LED meters: Measures sound wave voltage Peak 0dB = 100% (above that audio will distort) Overmodulation: distortion Recording clean sound Monitor with headphones Test record Patience
- 11. NO MIC? Background/Ambient noise should be minimal Place subject in close proximity to the camera Turn off radio/TV/Control audio as much as possible Much easier to control audio indoors vs. outdoors
- 12. Next Assignment Due April 2 Create a promotional business narrative Identify a local business, contact owner, offer to create a documentary styled promo video. (visual businesses are best) Record good sound Capture appropriate visuals Edit to tell the story Use company logo/colors for graphics Three person team/producer/writer – cameraperson –editor Proposals due next week.
