QTICM 15 - Comparing MPEG to Cinepak (1-Aug-95)


Q How does MPEG compare to other compression schemes, such as Cinepak?

A MPEG is a standard. Video CDs that are somewhat popular in Europe have only MPEG material. MPEG is a stream-based system with a highly interleaved data content. An individual MPEG 'sample' can be over five minutes long, and MPEG frames have both backward and forward temporal-compression dependencies. While you can create an MPEG editor and add additional tracks, it is difficult, and there is no standard in place yet for adding tracks.

QuickTime, which is a time-based-sample media format, makes it easy to edit and rearrange samples, and has a finer granularity concerning media samples. The track concept is already in place. Therefore, we recommend that you use MPEG for playback and QuickTime for handling multimedia container-type media.
