| Brendan, I compared the post-render against the "master" render in Premiere Pro, lining them up on a timeline and then toggling the upper track on and off. I can send you the files if you want to PM me with an email I can send a hightail link to. Easily reproducible though, I'm sure. The shift seems more than what you would expect from a single re-encode pass, having tested multiple generations of ProRes re-encodes for a long time. Robert W.

At least in my limited testing, i could find no visible difference between the RG output and a direct AE output using ProResHQ and 4444.

ProRes movies often look different in QuickTime player. And ProRes is a lossy YUV codec, so you expect at least a small change from the original RGB. > > If there's something beyond that, send us some steps to reproduce and maybe we can get to the bottom of it.
