Here's another weird one.

Got sent a QT off the offline seq. Converted to prorez for fcp previz edit. Dropped onto new timeline and set all fcp setting correctly. Spliced the edit with the edl and all cuts matched.

Render out of shake preview shots (VFX)(6 in an edit of 18 shots) in prorez. all fine.

Drop onto layer 2 in fcp the vfx over the guide offline track. all fine

Export seq to prorez QT to send to client. import to fcp. all fine

Now.. open that exported QT in QT itself and about 8 frames from the end of shot 3 the gamma changes and then on shot 4 half way through the gamma bumps back up. Shot 3 is a shake render.. 4 is untouched import :-/ ???

It plays fine in fcp though :-/ A gamma change on a shot I could kinda get.. maybe.. knowing QT! but in the middle of a QT ?

So I tick the little "compatibility" button in QT and there is a subtle drop.. mainly in the reds. Untick and a massive gamma jump.

Ok so on a single clip maybe.. but in the middle of clips?

Resolved by selecting "recompress all" on export from FCP.. which obviously took longer to export!
