As a general rule, high-res full color animations are directly dumped
to some form of image storage such as laser disks, video tape, film,
etc. At 118 Mbytes per second of animation (1280x1024 at 30 fps),
digital is not very practical. Thats 7 Gig for a 1 minute anim.
Also, non-destructive compression generally doesn't do enough on
full color images to make it worthwhile.
