DNxHD 175/185x 10 bit and play back in Quicktime Player on Mac
Hello Folks,
I am wondering if there is the same problem with QUICKTIME playing back a 10bit 175/185 DNxHD .MOV as 8bit as, there is with playing back a 10bit mov in FCP.
I’m noticing some banding in the sky that I would not expect in a 10bit MOV when I look at the files in QUICKTIME.
What ya think?
thx!

Having a 10 bit file does not mean it contains any 10 bit information. How was it shot? How was it brought into the system? How was it processed in the timeline? How is it being viewed?
HDCam, DVCProHD, XDCam HD, XDCam EX, HDV… all 8 bit formats.
Even native HDCam SR brought in as 10 bit could end up going through some 8 bit processing in the timeline depending on certain settings and what was done to it.
An older or cheaper LCD monitor might be only a 6 bit panel. Even most of the best LCDs are 8 bit. Most graphics cards output 8 bit.

Sorry for the ambiguity.
The 10 bit DNx files are trans-coded downconverts from 4k R3D files, processed through Red Rushes. I’m looking at the files at there native resolution (1920×1080) on a brand new 30″ Apple Cinema Display.
I’m wondering if there is the same known problem with the newest Quicktime Player playing back 10 bit DNx files as there is with FCP’s known problem, of only playing 10 bit back at 8 bit.. Seems plausible.
thx,
Chris
