user6532: I've just finished a music video in Resolve and exported it as Mov/Prores422HQ. It looks correct when played back in Quicktime and in VLC, however when I upload to YouTube, there is a huge gamma shift and the blacks look washed out.
YouTube on the left, Quicktime on the right:

What can I do to mitigate this gamma shift?

user6532: I managed to get an acceptable result by exporting as Mov/Prores 4444 and a Timeline Colorspace of Rec 709 Gamma 2.2.
