When creating MOV files, setting the -color_range option does not seem to have 
any effect. What am I doing wrong? Could it have anything to do with the 
removal of the yuvj pixel formats?
Is setting this metadata even possible in the MOV container, or is it something 
that is expected to be flagged at the stream level? I was having difficulty 
finding info on where this info is even located in a file in both: 
https://developer.apple.com/library/archive/technotes/tn2162/_index.html and
https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTFFPreface/qtffPreface.html

Worrying, if I set a value of jpeg, mpeg, or 0, ffprobe says that the file has 
TV range.

How to replicate:

$ ./ffmpeg -f lavfi -i testsrc  -color_range jpeg -c:v prores -t 1 
prores_jpeg.mov

However, when setting the same flag '-color_range jpeg' using Matroska, 
mediainfo picks up on the colour range flag, but ffprobe still says tv:


$ ./ffmpeg -f lavfi -i testsrc  -color_range jpeg -c:v prores -t 1 
prores_jpeg.mkv
