Handbrake: x265 or VideoToolBox conversion to MP4 vs DXV High Quality: colours get corrupted

Wire: 7.8.0
iMac 5K 2017 Big Sur
Handbrake: 1.4.2

Not a Resolume problem, but might be of interest to other Resolume users.

While Handbrake can handle DXV3 Normal, for some reason it corrupts the colours when converting DXV3 High. See attachment right.
