Cinepak
Cinepak is the most widely used cross-platform, software-only, scaleable codec (compressor-decompressor) for creating video for distribution on CD-ROM, game titles, and over the Internet.
Cinepak compressed video can be played back on any licensed platform. QuickTime is required for playback on Apple Macintosh and MacOS compatible systems. For playback on a Windows OS platform, either Video for Windows or QuickTime for Windows is required. No additional hardware is required for playback. Cinepak compressed video can be decompressed on machines as "lightweight" as an LC III, or a 20Mhz 386.
Cinepak uses a vector quantization algorithm, which allows it to play back at higher frame rates on most systems. As a software-only codec, it requires no special hardware for compression or playback. The Cinepak codec allows generation of bit stream with a stable and predictable data rate. This facilitates distribution of compressed video on CD-ROM and on the Internet. On playback, the Cinepak codec uses very little processor bandwidth, leaving plenty of processor power available for other tasks. This is of significant benefit to developers of interactive content.
