I've transcoded movies from a pc (AVI uncompressed) to quicktime
sorenson 3 using cleaner 6 on the mac. (The preview window in
cleaner shows the footage with the correct contrast).
The movies a created using aftereffects on the pc, btw.
Any suggestions what I can do about this?
Btw, in my own application, the movies are decoded to a offscreen GWorld
wrapped around a 24 bit RGB byte array; using no hardware acceleration
what so ever.

It is supposed to be there, yeah (I got 10.3.7). If it was there, would
adjusting this make a difference?
Btw2, a friend of mine is having the exact same problem under windows.
He does have the video controls, but the adjustments are not stored,
every time a new movie is opened they are reset.
thanks.
Jelle
