Did you check the suggestions on <http://mac.povray.org/support/video/>?
They apply to every program.

Oh, well, I'm not actually using POV-Ray generated images in this video. The
problems I'm having seem to be specific to this one version of this one
program, regardless of the quality or nature of the source video. Thanks for
the link, but it doesn't seem to help. Were there any specific tips on that
page that you were thinking of?

Yes, the one with the frame differences. If I were you, I would try to
compress a short sequence with very small movement (i.e. some sphere moving
one pixel each frame). If you cannot get it to compress well, you are most
likely dealing with a program defect. If it works, you may want to try your
material with another program or maybe another format like those mentioned
on the page (MPEG-2, Divx). In particular if you try with any current Divx
encoder, you basically get nothing more than a *non*-standard compliant
MPEG-4. Thus, if this works but the built-in MPEG-4 compression doesn't,
you know where the problem is.
BTW, there is one other thing to remember about MPEG-4: Make sure you do no
accidentally specified that the video be compatible with a specific ISAM
profile, because those limit the video resolution, i.e. ISAM profile 1
limits it to 320*240 pixels. In short, you may simply have accidentally
enabled some compatibility setting you don't desire...
Another thing is, I am of course assuming you are not using any of the
Windows built-in MPEG-4 codecs, because they are all more or less defective.
Especially the very old ones cause endless problems because they existed
long before the standard was ratified. So I assume Adobe Premiere Pro has a
well-done codec built-in. And I of course assume you also use Adobe
Premiere Pro to view the generated MPEG-4, right?
Anyway, maybe there is a manual online or you could post screenshots of the
settings dialog on some website?
