Colours of HDR exports from Premiere Pro and After Effects never match

Thank you Eric, I had not heard of the OCIO color engine before. I tried the settings you suggested as well as using 'scene_linear: ACEScg' for the override media color space. The issue was not fixed and the footage no longer looked HDR in the timeline or when exported. I was really hoping that would work!

Interpret footage settings:

Hello PG73, 
Premiere and After Effects color management can definitely be a little tricky, especially when it comes to working in the wild ends of HDR. Have you had a chance to try out our OCIO color engine in After Effects?

It was built specifically to make hand offs between After Effects and other post-production appa easier and more accurate. (*edit, however OCIO is not currently supported in Premiere Pro)

Try the following settings in After Effects and see if it solves the color shift issue?

Please let me know if it works or not.

Eric

Ooops, my bad! I was traveling yesterday, popping in on my phone, and I missed the post with the Settings tab.

I'm curious what happens if you turn auto tonemapping on ... that is interactive with auto log detect, and although some of the interactive nature has been explained, I'm not sure what it might do in this case.

And @David Arbor (experienced Ae wiz) or @eric escobar might be able to help.

Sorry, I don't see any other Lumetri Settings tab than what I provided above.

Color Workspace, Lumetri panel. Settings tab.

Thanks, I managed to find the Lumetri Settings tab, I don't ever remember seeing this before, at least not since having this issue. I have Lumetri Color set up as an fx within the Effects Controls panel and that only shows the 'Edit' and not the 'Settings'.

I don't know how to be more clear ... I'm not interested in any color manipulation you're doing to the image.

I'm ONLY interested in the color management settings, which are all in the Lumetri Settings tab. Clearly you've not looked at that tab.

This discussion is entirely about color management, not manipulation.

I work for/with/teach pro colorists mostly based in Resolve or Baselight. I teach how to accomplish most of what they do in those apps in Premiere. And have for some years now.

Your problem is simply non-matching color management settings.

And with the heavy use in professional needs by several million users daily, yes, many people do match CM between Premiere and Ae.

Thanks for your response, though I'm not convinced the "IF you use appropriate matching settings, it will work. If you don't, it won't", I suspect AE is doing something different to PP and so they will not match, but I could of course be wrong. I would love to know if anyone has got it to work.

When you say a screenshot of "the entire Lumetri Settings color managment tab in Premier", I may not have made it clear, but I have not applied any colour edits. The issue can be seen by purely bringing in footage and then exporting.

I am comparing the footage before doing any edits, so even with dynamic linking, as soon as the footage goes from PP to AE and I apply the below override the footage goes from being Rec. 709 (default) to Rec. 2100 HLG, and if I save and go back to PP the footage will not match in the timeline or more importantly when exported. 

AE override media colour space:

Well ... let's start again. Note that the dialog for Ae above specifically states the media is not color managed? Not ... workable if trying to match something else.

So ... screen grabs of the entire Lumetri Settings color managment tab in Premiere, so we can see everything ...

And a screen grab of your color management panel in Ae. Do not use preserve RGB.

IF you use appropriate matching settings, it will work. If you don't, it won't. 

Yes, I have tried all of the 'override media colour space' options that I think might be suitable, and choosing 'Rec. 2100 HLG W203' is what I think should be the right option, but this gives exactly the same result as ticking that 'reserve RGB' box.
