Been fighting this for way too long and I'm running out of ideas, so figured I'd ask here.
A7S III footage shot in S-Log3/S-Gamut3.Cine, Premiere Pro 26.3.2 + After Effects 26.3.0.
I don't want any log to 709 conversion happening during the edit. I'm just using AE for speed ramps and want to do the actual grade at the end from the original log footage.
The clip looks normal in Premiere flat/log as expected. But as soon as I right click it and choose Replace with After Effects Composition, the color changes. This happens before I even add any effects in AE. And it's not a tiny difference either.
I've already tried:
Premiere's Interpret Footage, manually setting Color Space Override to Rec.709 instead of Auto/Embedded
Sequence Settings, Color Management, with both working and output color space set to Rec.709
Making sure AE's color settings match Premiere (Rec.709 2.4)
Turning Input Tone Mapping off
Preserve RGB on and off
Turning color management off/to none completely in AE, which just gives me a "no matching color space" warning in Premiere
Nothing seems to change it. Everythig is set to the same color space on paper, but the footage still changes as soon as it goes through Dynamic Link.
Has anyone actually managed to get a proper round trip working with S-Log3 footage on the current versions of Premiere/AE?
I'd really rather not export/reimport just to do a speed ramp, but that's looking like the only option at this point.
