Oh okay, thanks for the response though! Yeah, this whole space is such a mess and I'm not even trying to do something at a professional level (which is why I'm using my Mac screen and not a reference monitor).
There are a lot of blog posts and YouTube videos about matching Davinci, QuickTime, YouTube, etc. but so far I've only found answers for SDR. Native Mac screens have a true HDR mode built in you can see clearly when you play any HDR video in Photos, QuickTime, etc. The normal UI is capped to, I believe, 500 nits, and then HDR video unlocks up to 1600 nits. I can see my settings in Resolve are unlocking the higher brightness, so it should be triggering the MacOS HDR pipeline, but it's too bright, so I agree the gamma must be different somehow.
- aikinai 4y agoI played with it a bit more just now and I'm very close! For anyone who stumbles on this thread in the future I found that in Resolve if I disable automatic color management, and set the output color space to "ST2084 500 nit", then the gamma seems to match Quicktime exactly (though I'm not a professional). It's still clearly going over 500 nits in the viewer, so I guess that's some sort of baseline that matches the "default 500 nits but go over for HDR" that Macs do. The colors are still just a bit off and I think that might be something about how Quicktime and Resolve are interpreting the Sony HLG3 colors which don't exactly match the standards. I might try some of the normalization products offered here[0] later when I get time. [0] https://xtremestuff.net/sony-and-hybrid-log-gamma-hlg/ https://xtremestuff.net/sony-and-hybrid-log-gamma-hlg/
