Compressing Digital Video

Codec stands for Coder/Decoder and is a software or hardware driver that allows the computer system to play or encode an audio or video file. These files can then be shared and played back on any computer system that has the Codec installed/loaded. An advantage to using a Codec is that the audio/video files can be compressed, significantly shrinking the file size for efficient distribution. QuickTime and Windows media formats contain various Codecs for video and audio playback. Additional Codecs can be added for additional playback compatibility. Common Codecs includes (lossy) MPEG1,2, and 4, DV 25, 50, 100 and (loseless) uncompressed.
