I should add I tested checking RGB level on QT ref export and saw no difference in the resulting files when ama'd back into Avid.

I still think that works pretty well but I noticed that when I exported the 10 second slate white type over black as a QT Ref from Avid DNX 220 sequence the reference movie looked a little washed out on the computer screen, which I would expect due to the 601/709 16-235 levels from the Avid ref QT set to 601/709 on the export options. Then when I export it from QT Pro to a self contained Prores HQ 422 the resulting movie shows RGB like black levels on the computer screen. AMA linking back to both the reference movie and the prores self contained movie in Avid and both look correct in level and other than a slight gamma difference they are correct. So the video essence is the same in both files but once exported to prores QT player stretches the video level on desktop playback. Not

Ultimately it was the Avid bars had been imported at the wrong level so the resulting file exports for bars were at the wrong level and I figured it was due to Prores QT crap but in this case it was properly representing the incorrect level of bars just as they were originally wrong in Avid. How do you miss that? Man it's time to start taking names and whacking pee pees. ;-)
