(I have PowerPoint 2011 for Mac, Quicktime 7 Pro, and Quicktime 10.)

I'm exporting PowerPoint presentations to .mov via the "Save as Movie" function, then going into QT7 Pro and setting them to auto-play in fullscreen mode with PPT's transitions intact. So far it's working fine, except I need to save one out as H.264; currently PPT is exporting the movies as "MS Powerpoint Movie" instead.

If I open the .mov exported from PPT in QT7 and "Export" using H.264, the resulting movie file looks washed out and the transitions between slides no longer function, so that's not good. How can I change PPT's movie file to H.264 while not screwing up the movie like that?
