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. I mean NO difference, even blown up 200%. Correct, the combining of movie segments does not involve re-encoding, while the Post Render Actions do (since they usually are converting your render to a different codec). If you see shifts in the Post Render Action movies, are you doing the comparison in After Effects? 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. Maybe the FFmpeg command line could be altered. Brendan |
