If the video complies to broadcasting standards like ITU-R BT.601/709,

artifically (e.g. by a 3D renderer or heavy filtering).
My remark is rather directed to the meaning of the parameter name,
though. A boolean answer is valid for a question like "Does this video
have *full* range? Yes/No". But asking "Does this video have (any)
*range*?" doesn't make sense; you would rather ask "Which range does
this video have? TV/PC".
Video cannot have "either any range or no range". Therefore at least
the name "--[no-]range" is wrong. A name like "--[no-]full-range"
would at least make some sense, but possibly looks a bit complicated.
Understood. I can setup the tv or pc option. If I add the auto option
now it won't be functional yet.
by the way, there are other options where bt709 is possible, can that be
used to determine range?
