Hey everyone.
I have a problem with broadcast files, created with Adobe Media Encoder (ARD-ZDF certified). So this seems to be a Adobe related problem, but maybe I can get some input here. When I export a file using the ARD-ZDF HDF02a-1.1 Profile preset, the MXF file has (among others) the following meta data (in MediaInfo):
Color range : Limited
colour_range_Original : Full
The file itself is encoded in "Legal Range" (like every common YUV encoded stream), but FFmpeg for example seems to interpret these files als "Full Range" (Premiere and Resolve are fine). As a result, all trancodes are "wrong" (lifted blacks/lower highlights). The "_Original" flags are the one from the stream, the tags witout the "_Original" are the flags of the container as far as I know.
Where does the "_Original" flag come from? In my test the source was a ProRes (444 and 422HQ) file (Legal Range).
Of course I am able to fix this issue during transcoding in FFmpeg, but sometimes I don't have the choice in automated workflows.
To sum up: is the "colour_range_Original : Full" correct and necessary on ARD-ZDF HDF02a-1.1 Profile files? The TecSpecs say "Color Range [221W]: 897" (https://www.ard.de/die-ard/ARD-ZDF-HDF02...ks-100.pdf). Dunno what that means...
