rendering this @ DNxHD175x 23.98fps.
Looked a little more carefully at it today. Seems like it is having trouble with blacks, and inverting them once they get below a certain threshold. I enabled 10 bit processing and that did not help. Found that if I set the clip lows to 0 and the highs to 255 it seemed to correct the problem, but kinda a pain to need to do that on every clip.
Best,
Dan
