I have tried the MPEG options in IDL and have had a frustrating experience.
It sucks.
This is what I have been doing. It may be a bit clumsy but I am getting what
I what:
1) use IDL to generate the individual frames you want in the movie and set
them aside.
2) use another program to string these individual frames together. For
example, I generate JPEG movies using a program called MovieGear (shareware,
about $35). It also does optimization. Playing is great, forward or back,
pause, etc is ok.

I'm afraid that little MPEG button on XInterAnimate has
given the impression (false, I think) that you can just
willy-nilly make MPEG movies out of anything. The MPEG
standard (created for video, remember) is more complicated
than that.
I'm still learning many of the details, but I do know
that people have had much better luck creating MPEG
files if they keep the "window" or frame size fairly
small and certainly some integer multiple of 16. RSI
assures me that some improvements have been make in
IDL 5.4, but some of these problems are simply the
result of pushing this standard into places it was
not meant to go.
Best Regards,
David
