majoraxis Posted January 12, 2021 Share Posted January 12, 2021 When you export to a Quicktime file from Resolve, if what you see in the viewer in Resolve does not match what you see when you playback the resulting Quicktime file - check out the following article: (It's a long article, so I summarized what worked for my scenario below.) https://www.thepostprocess.com/2020/03/16/color-shift-fixes-from-davinci-resolve-to-mac-displays/ Here's the steps I followed for my 2017 iMac running 10.13.6 and Resolve 16.2.8: 1. In System Preferences->Displays->Color (Display profile:)->Display P3 2. In Resolve Preferences->General.“Use Mac Display Color Profiles for Viewers.” to grade through Apple’s P3 display profile. 3. In Resolve Delivery->Custom->Advanced Settings->Color Space Tag->rec.709, and Gamma Tag->rec.709. In my tests, it worked great. Quote Link to comment Share on other sites More sharing options...
kye Posted January 13, 2021 Share Posted January 13, 2021 Yeah, this is a major issue. It's because the environment for colour management is basically a huge mess, and why BM still sells and recommends their own hardware monitoring - because it bypasses all the OS and UI colour tomfoolery. I read in one thread about applying an extra node in Resolve to compensate, I think it was a gamma conversion of some kind, and the idea is that you just grade as normal, apply the extra node, export, then disable the node again. I've found it makes a pretty close match, including all the way to viewing your video on YT, certainly close enough considering the woeful variation in colour performance of the various devices out there.

majoraxis Posted January 13, 2021 Author Share Posted January 13, 2021 @kyeThanks for the information! I’m not applying and removing the LUT with the Display P3 work flow and the results match. For people on iMac with Resolve I would try the 3 steps listed above (without the LUT), as it is a no fuss workflow. That said, if you do try the 3 steps (to color consistency), please report back your experience to confirm or deny the validity of this workflow (for iMac users). Thanks!

KnightsFan Posted January 13, 2021 Share Posted January 13, 2021 Why would you set your display to P3 if you are grading for Rec 709? Quote Link to comment Share on other sites More sharing options...
majoraxis Posted January 15, 2021 Author Share Posted January 15, 2021 @KnightsFan Great question! Honestly, I don’t, but I switched the color profiles back and forth and P3 looked the best to me. It looked very similar to the default iMac color profile. I think the key is to bake the color space and the gamma settings into the resultant QuickTime file and set Resolve to Use Mac Display Color Profiles for Viewers I assume if you had your own calibrated color profile it should work just as well.
