The larger the keyint, the better the quality (potentially).

mv0 does HORRIBLE things to the video in my tests (with MPEG1/4). It
causes some very weird and terrible looking macroblock judder.

You'll never get *lower* quality using a larger dia size.  If encoding
time isn't a problem, why not use a larger value?

*cmp=2 works great on animation, but makes live action blocky. If you
aren't using strong deblocking on playback (which I imagine flash
won't), it looks terrible.

There are plenty more options in the DOCs that you could be trying.
