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.
