Cinepak
Cinepak is a video software created to encrypt 320 x 240 resolution video at 1 x (150 kbyte/s) CD-ROM transfer rates. The codec was created by Peter Barrett of SuperMac Technologies. It was debuted in 1991 as a part of Video Spigot, and again in 1992 with Apple’s QuickTime video package. By 1993 it was standard in Microsoft Video applications as well.Cinepak separates the video into “key” images and “intra-coded” images. Then, those images are split into bands, horizontally, which contain color palettes specific to the key images. Vector quantization is utilized to identify which color palettes match the subdivided pixel blocks. Files created in this way are generally seventy percent bigger than MPEG-4 files.
