I have several animation files that just came in as QT files for use in PPro 1.5. They play fine in QT Player,, but stutter when in PPro. None are larger than 450MB. I thought QT mov files were compatible with PPro. What am I missing here? I tried converting to MPG2 files, but that only made timeline playback worse (though they played fine in Preview Monitor).
Do a forum search for animation - there are LOTS of past discussions about problems
Converting to MPG is exactly the WRONG thing to do... MPG is a compressed delivery format, not meant to be edited
Convert to DV AVI Type 2 with 48khz sound
