- 12. Laura Johnson Digital Video Capture Digital video capture is where you convert analogue video signals generated by a video camera into a digital format. Video capture from analogue devices need a certain video capture card that can convert them signals into digital form then compress the data. There also more commonly digital video devices that capture images and transfer them to a computer through a standard serial or parallel interface. Firewire cable: A fire wire cable allows you to capture a video that's been recorded onto a camera. You just connect it to you computer and choose the software you are using then through the cable it will transfer your video from the camera to the device.
- 13. Laura Johnson Compression Compression can be either in lossy or lossless form. This can be useful because it reduces resource usage like data storage space or transmission capacity. Lossless compression reduces a file size with out any loss of quality or information. Lossless can be applied to both image and audio files such as JPEG 2000 and Apple Lossless compression, these can be used to make lossless compressed files. The lossless compression is normally much bigger than a lossy file as since there is not quality lost the file is much bigger than an image/audio file compressed by lossy sometimes by a much as tenth in size. Lossy compression makes a file smaller but loses data and quality from the original version. Lossy is mainly used for image files such as JPEGs and sometimes audio files like MP3s or AAC files. The effects of using lossy could be jagged edges or pixelated areas of the image or if audio may produce a watery sound or reduce the dynamic range of the audio.
- 14. Laura Johnson Digital Video Formats A videos file extension/format is referred to as the container. Containers have codec's that they only use and others often use different codec's. Advanced Systems Format (.asf) – ASF is a Microsoft container that normally houses files compressed with Microsoft’s WMV codec. ASF can include digital rights management which is a form of copy protection which gives it an advantage to other digital formats. Quick Time (.mov or .qt) QuickTime was created by Apple and covers a wide variety of codec's. Apple decides what it supports Advanced Video Coding, High Definition (AVCHD) AVCHD is mainly used as a container for data compressed with H.264. Its calibrated between Sony and Panasonic as a format for digital camcorders. Its stored and played back on disks and other storage devices like compact flash drives and SD Cards making it a file based format. The newest version supports 3D and supports both standard and different high definition variants from 720 to 1080p.
- 15. Laura Johnson Flash Video (.flv or .swf) Originally flash was created by Macromedia which was then taken over by Adobe in 2005. It comes in many versions, older flash video mainly uses the Sorenson codec while newer flash uses H.264. Its a hugely widespread container format used for streaming videos across the web. Its disadvantage is that it wont play on iOS devices such as iPods and Iphones as apple labelled the format ‘buggy’ and blamed it for problems with the Apple Operating System. Audio Video Interleave (.avi) AVI was developed by Microsoft and released with Windows 3.1. AVI have been a work horse of digital video. Many legacy videos in AVI format can be found on the web. With AVI you can specify an aspect ratio. MPEG-1 This is nearly only used for Video Compact Disks. This is very popular everywhere but noticeably never used in the U.S. The quality is much lower than DVDs. MPEG-2 (H.262) MPEG-2 is a container format but the is also a codec named the same. It is used for only DVDs and to broadcast High Definition Television Digital Video Formats
- 16. Laura Johnson Streaming Methods Streaming media is a form of multi media where its received and given to an end-used and at the same time been delivered by a provider. Its a flow of videos through the internet. The video is normally sent from pre-recorded video files but can also be distributed as part of a live broadcast feed, the signal is converted into a compressed digital signal and transmitted from a special Web server that is able to do multicast, sending the same file to multiple users at the same time The 2 main methods of streaming videos are streaming severs (true streaming) and HTTP streaming. When creating video stream you need to understand the video file format and the streaming method. Streaming is fast becoming the most popular internet technology. The most common streaming technology is Video On Demand.
- 17. Laura Johnson Data Transfer Rate Data rate is the rate at which information is being transferred. DTR (data transfer rate) is how much of digital data is moved from one place to another in a given time. The data transfer is viewed by the speed of travel of an amount of date going from one place to another. In general the bigger bandwidth of a certain path the higher the data transfer. Rates that video play and record at- 16 kbit/s – videophone quality (minimum necessary for a consumer- acceptable "talking head" picture using various video compression schemes) 128–384 kbit/s – business-oriented videoconferencing quality using video compression 1.5 Mbit/s max – VCD quality (using MPEG1 compression) 3.5 Mbit/s typ — Standard-definition television quality (with bit-rate reduction from MPEG-2 compression) 9.8 Mbit/s max – DVD (using MPEG2 compression) 8 to 15 Mbit/s typ – HDTV quality (with bit-rate reduction from MPEG-4 AVC compression) 19 Mbit/s approximate — HDV 720p (using MPEG2 compression) 24 Mbit/s max — AVCHD (using MPEG4 AVC compression) 25 Mbit/s approximate — HDV 1080i (using MPEG2 compression) 29.4 Mbit/s max – HD DVD 40 Mbit/s max – Blu-ray Disc (using MPEG2, AVC or VC-1 compression)
- 18. Laura Johnson File Size File size measures the size of a computer file. Normally it is measured in bytes with a prefix. The amount of space on the disk consumed by the file depends on the files system. All files on a computer uses a certain amount of resources when sent over the internet or stored. Kilobytes and Megabytes is what its measured in.
- 19. Laura Johnson Aspect Ratio The aspect ratio is the ratio of the width of a shape to its height. when the width is larger than the height, the shape is positioned as landscape rather than portrait. The aspect ratio is expressed as two numbers separated by a colon (x:y). A common misunderstanding is that x and y represent actual length and height. This is false, they actually represent the relation between width and height. As an example, 8:5, 16:10 and 1.6:1 are the same aspect ratio. The term is most commonly used with reference to: Graphic / image Image aspect ratio Display aspect ratio: the aspect ratio for computer displays. Standard photographic print sizes Motion picture film format
- 20. Laura Johnson Media Players Media players is computer software used for play back multimedia files. The majority of media plays can play both audio and video but some focus on only one or the other. These are known as either audio players or video players and normally have a user interface tailored for specific media type. Windows Media Player: Windows media player was developed by Microsoft Windows and is all ready pre installed. Its used for playing both audio and videos and viewing images. QuickTime: QuickTime is an extensible ,multimedia framework created by Apple. Its used to show digital video, picture, sound, panoramic images and interactivity. iTunes: iTunes is a media player, library and mobile management application created by apple. Its used to download, play store and organize digital audio and video. VLC: VLC media player supports most audio and video compression methods and file formats. For example DVD-Video, Video CD and Streaming protocols. It can stream over computer network and transcode multimedia files.
- 21. Laura Johnson Digital Rights UK Digital rights Digital rights is the human rights that allow individuals to use, access, create and publish digital media or to access and use computers, other electronic devices and communications networks. Different human rights have been made relevant with regard to the Internet. Some of these are freedom of expression, data protection and privacy and freedom of association. Digital restrictions management: DRM is the practice of imposing technological restrictions that control what users can do with digital media. When your prevented from copying or sharing a song you are being restricted by DRM.
