Rec 709-A tells the QT Player to adjusted the gamma to what should be expected. So you should see a perfect 1:1 from inside Resolve to QT player. The Rec709 tag is for Mac displays from what I can find. So long at you get the same results on upload. Your good. If you tag just Rec 709 in PC you should still have the same levels. Thanks
This is a problem I am grappling with at the moment so I was so pleased when your video arrived in my feed that I tried it immediately. Doesn't work for me on a Mac mini. There is still a gamma shift downwards (or numerically upwards!) on the upload to TH-cam compared to the file viewed locally in the QuickTime viewer. So I am still looking for a way of viewing videos in the DaVinci viewers which reflects what I will see when they are uploaded to TH-cam.
Hello @Stanthebop, Check these preferences: Under System/General make sure "Use Mac Display Color Profiles for Viewers" is on. and "Automatically tag Rec.709 Scene Clips as Rec.709-A" I believe that should fix it on your end. Letting Resolve know it's in a Mac viewer environment. I did a test on my screen vs. playing on TH-cam and got a match.
I'll look into this a bit more since you are still getting a bit of a shift. I've been doing so renders lately with mixed media and getting good output. If I stumble upon another setting I'll let you know! Thanks for the sub!
Thanks for this. As I'm using a PC, is Rec 709A only for when coming out of a Mac computer?

@@TransientMobile Thanks very much. This largely solved the problem. Viewers are still slightly lighter but something I can live with. Subscribed.
