Every single one that Quicktime supports.

Sounds like a problem with Snapz compression settings and/or Quicktime 
internals.  Try emailing Andrew Welch at Ambrosia Software about it or 
use the forums on their website.

Animation codec uses ARGB pixels, so send a 'colorspace rgb' to 
pix_film/movie to have it display properly.  The default colorspace is 
YUV.  I wrote up a little FAQ about colorspaces and other OSX related 
GEM items here:

Everything but QTVR, video effects and export listings are supported.
