DNxHD Sequence with “Render in 8-bit YUV with Color Levels set to RGB in Advanced Options of DNxHD Codec”
and setting the ‘dnxhd’ option to either: Full RGB (0-255) & Gamma Ext. or ‘Full RGB (0-255)’ would appear to have
the most consistent color levels since FCP expects RGB video to be in the Full Range. Also it appears that the added
Gamma Extensions of Full RGB (0-255) & Gamma Ext. has no difference and is visually the same to the option
‘Full
RGB (0- 255)’ when a DNxHD Sequence is setup with “Render in 8-bit YUV with Color Levels set to RGB in
Advanc ed Options of DNxHD Codec” in our above tests.
Although you could set the ‘dnxd’ option to SMPTE RGB (16-235) and you could setup a DNxHD FCP Sequence to
“Render in 8-bit YUV with Color Levels set to 709 in Advanced Options of DNxHD Codec” to work in SMPTE RGB
Range
– please note that this would be a more complicated workflow and this could produce unpredictable color level
shifts when working with different effects or with i/o boards as they would be expecting Full Range RGB.
