ffmpeg -i input_video.mov -vf setrange=limited -c:v ffv1 out.mkv

That command will tell ffmpeg that range is not full but limited
and will not do lossy conversion with swscale at all.
You will need to signal that encoded video is still full range somehow in container,
otherwise you will get correct hash but output display will think
its really limited while it is actually still full range.

FFv1, still, as time of this writting does not support signaling
this color range in any way in bitstream.
Dunno if matroska container supports it.

Anyway you will need to find another way to store such metadata.
