From within IDL, there is only the quality factor you mention, to my knowledge.
Also, MPEG playback speed is standard at around 28-29fps, which is a video
standard. You can get a player that will play MPEG's slower, like VMPEG. Or
you can convert to another format that allows more control over this. There
has been a few posts to this ng about good formats for animations, MPEG is
only one and is most idealy suited to video. You can always duplicate frames
if you aren't concerned about file size. I'm not sure what the color problems
are coming from.
