i agree that cinepak looks terrible, but i feel like i'm stuck using it because:
- the files are relatively small and they decompress quickly, so i can
play many of them simultaneously
- i can keyframe every single frame, so i don't get any hiccups
scrubbing/scratching the video
so what i'm asking is:
given that i want to be able to play back many (at least four) video files simultaneously while manipulating their playback speeds and directions (like scratching records on turntables), what is the best codec to use?
also am i making incorrect assumptions given the capabilities of modern hardware? that is, do i really need to keyframe every single frame in order to get smooth playback in both directions and at rapidly varying speeds? and do i really need to be concerned with having file sizes small enough to reside in memory and not streamed from disk? _ j

hi all ...
i'm currently working with a gem patch to play back videos files encoded with the cinepak format on linux ...
Why on earth are you doing that? Cinepak is the very first lossy codec developed for quicktime around 1991 and the quality is horrendous. It's very unlikely that you would encounter any content compressed after 1996/97 in Cinepak as literally every single codec after it is superior.
and what's the prefered (most stable, hq) video codec for linux ...
Photo-Jpeg? Uncompressed 4:2:2? Anything other than Cinepak!
