You can't reliably flag file as Rec.709 with 2.4 gamma. When it comes to MOV videos OSX color engine does understand few flagging combinations (some combinations from this tables: ), but not exactly the ones which are commonly used, so this the problem.
It's lack of reliable technology on OSX or WIN to display videos taking into account their different color spaces (+headers flagging!) and also display settings/possibilities.Īnother issue is the we use Rec.709 with 2.4 gamma which is actually something "made up". You have to have a color-managed output, like one from a Blackmagic display card, preferably on a calibrated Rec709 display.Īll of this is irrelevant to the actual problem of preview difference between Resolve viewer and QT X ( they should match).įact that both may be inaccurate is yet another story, but we don't care about it here as all what is needed is same preview between QT X and Resolve (when I grade my holiday videos I watch them only on my Mac screen so I don't care about reference preview). 667-668 of the Resolve 14.3 manual: "Limitations When Grading With the Viewer on a Computer Display." This goes into some detail why you cannot accurately monitor directly from the computer and operating system. I think Resolve should really start handling that itself, if BMD wants Resolve to become a one stop shop, rather than having to go to outside tools for export to the real-world consumer.
