Hi first time here hope this topic will help the others and I can found a solution.
So Ive been grading in ACES for a couple of years now and Im really happy with the results.
Mainly for theatrical releases grading on projectors I go for DCI P3 D65 full levels and when working on a monitor Ive been using Rec 709 also at full data levels.
I came to a friend studio to verify a GAM graded on Rec709 @ full levels. Checked on a projection DCI P3 D65 also @ Full levels and the conversion is really good as usual.
Checked on another room with LG OLED at Full levels Rec 709 and its great too.
Then I also checked on another suite that has Video levels and the problem happened.
The room has a LG OLED on Video levels so Resolve is also set at video levels.
No matter if I set my GAM Open EXR at Full levels (to match my export setings) or at Video levels the result will look wrong, clipped blacks, wrong contrast, saturation and exposure.
My main surprise is that when working on ACES 1.1 (Resolve 17) No matter if I set Resolve to work on Full or Video levels it wont have any impact on the interpretation of my GAM. With RCM changin the data levels will work as intended.
Does it means that when working on ACES we always need to stay on Full levels?
Is it not possible or not recomended to do ACES on Video Levels?
Is it a problem of Resolve? A well know issue?
I might be getting confused but I always thought your Data levels just depend on your pipeline and monitoring but you can set them as you need if you just respect to match them on your software, Video card, and monitoring the result should be equal.
Hope someone can help me out, I could not find any info about it.
Thanks a lot.
