Greg have you looked at color bars when taking a dnx timeline and going out prores.? In my experience there is the slight gamma shift. Only if you stay all prores or all dnx do the levels stay the same on import export. At least that's what I saw one night a while back playing with mc V6 using the internal scopes. I think this is still true.

So I have been making video mixdowns and then the QT ref which seems to eliminate that problem. If I want to master out to Pro Res this way, any quality hit or is it best to export to Pro Res right out of Avid?
