Contrast change after update to resolve 15

[Joseph Owens]

[Tristan Hachmeister] “(blacks fully crashed)”

Usually means you have the video range set incorrectly. “Full” RGB vs “Video”Linear — the difference between 64-940 and 0-1024.

I always set all clips to Full after the XML import. I did this also in Resolve 12.
When grading a new project without the stills from 12, it works for me this way:

Setting the Data-Levels of the imported clips in Resolve to “Full”, grade them and then (for the roundtrip) set the format to ProRes422 and under the advanced settings set the Data-Level to “Video”.

Now the files look the same in both programs.

have you tried this: https://www.youtube.com/watch?v=YwjLuUR51gE
also: you should use video levels (most formats use it and if you override more shifts are likely to happen)
resolve changed the underlying engine and now works better with apple’s colorsync.
also: the viewer in resolve never shows the accuracy what an output via decklink would. sadly but that’s how they get you to spend money ☺ also, most formats are also rec709 gamma 2.4 – you should use resolve’s standard project settings about color which uses this automatically and compensates for your 2.2 system.

Thanks, I’ll try the colourprofile from the video.
But everything works fine with new projects and with the data/video-levels settings, I mentioned before.

Thanks for your help!
