Was looking for this question but haven't found much (probably failed at the search term).
Shooting with P4K 12:1 4K DCI @ 75/25, what settings do you use or should I use for master exports? Currently doing DNXHR HQ but not too sure whether I should have the constant bitrate checked or not. A lot of the scenes are "high" contrast, involving shadows/highlights pushed and foliage from outside (for instance my real estate jobs).
TDLR:
To Constant Bitrate or not to Constant Bitrate?

This box in Resolve has no real meaning (it's for ProRes). It should be graded out for DNxHR. As you found out- it only causes problems when ticked and I've seen same issue.
DNxHR can be VBR which is part of its the spec, but I don't think there is any tool generating VBR streams.
