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
