I'm trying to nail down a color and compositing pipeline between After Effects and Premiere for HDR video (High Dynamic Range). I've figured out how to get OpenEXR sequences to color match between After Effects and Premiere Pro (drop an EXR sequence into Premiere, drop same into After Effects and render out as EXRs without doing anything to them, drop the After Effects output onto a Premiere Pro timeline, and the two sequences color match with no shifts).
So I'm confident that my workflow color matches - that processing an EXR sequence through After Effects and putting it into Premiere isn't shifting color or gamma or anything like that.
My goal is to do HDR color correction in Premiere Pro with Lumetri Color and Lumetri Scopes in HDR. After Effects doesn't have HDR scopes AFAIK. I then want to apply those color corrections to clips in After Effects, because I'm doing several versions and things with that color corrected clip.
BUT....if I make a Lumetri Color setting in a Premiere Pro project on EXR sequence A, then import that Premiere Pro project into After Effects, find that Lumetri Color effect, then copy it to apply it to another version of the same EXR Sequence A and render out a new EXR sequence B from After Effects...sequence A doesn't match sequence B in Premiere Pro. At ALL.
Examples: Here's the Lumetri Scopes readouts of an EXR sequence I've imported into Premiere Pro and applied a Lumetri Color color correction on, compared with the same clip with the same Lumetri Color effect applied in After Effects, rendered out to a new EXR sequence and dropped into Premiere Pro:
...and here's the actual images from the program window in Premiere Pro. Again: EXR Sequence A with Lumetri Color effect applied in Premiere on the left; then the same clip with the same Lumetri Color setting applied in After Effects and rendered out to a new EXR sequence and brought back into Premiere on the right:
Now in the old days I would have blamed this on Quicktime doing some color shifting or oddness in the Premiere vs After Effects color interpretations, but remember I've already done render tests to show that WITHOUT Lumetri, they match dead on. So it appears Lumetri Color is inconsistent between the two programs. Does anybody know of a way to fix this?
I recognize that I could pre-render the EXR sequence out of Premiere and bring it into After Effects and work from there, but that introduces additional problems of render time and drive space and another intermediate file to track and media management and organizational time and...ICK. I don't wanna.
Thoughts, suggestions, anyone? Bueller? Bueller?
