As reported by @inohide in this thread -
https://www.steakunderwater.com/wesuckl ... php?t=5289exporting DNxHQ 4444 12bit quicktimes through saver node in fuStudio 17.4.3 is broken. The created quicktime has the RGBA channels mixed up in the wrong order. If you turn off "save alpha" in the saver node options the problems disappears.
DNxHQ is used in a lot of VFX approval pipelines so it is important that BM resolve this ASAP.
Tested and confirmed on win 10.
A workaround until it is fixed is -
WORKAROUND - insert a channel boolean prior to the DNxHQ 4444 saver node with with your image connected to the BG and these mappings -
Operation - Copy
ToRed - Red BG
ToGreen - Blue BG
ToBlue - Alpha BG
ToAlpha - Green BG
This pre-jumbles the channels so that the defective Saver node ends up with them in the right places and the outputted quicktime looks correct with correct alpha channel. Haven't done extensive tests but seems to work ok. Might be some help for someone in need while we wait for a proper BM fix.
