Comment:
hi,
Im having too the same problem but that's working in some case but not on
some others...
If I took a png then limiting it to a jpg it works
but if I took a jpg to limiting it to tv it doesn't work
I've got the same for the targa format (I'm using it for my broadcast work
and I can't find a way to limit the range on them...)
example who doesn't work... the black/whites levels are the sames
ffmpeg -i testalpha_%04d.jpg -c:v mjpeg -q:v 1 -filter:v
"scale=in_range=pc:out_range=tv" testalpha__191220_ at 25p_jpg-1_%05d.jpg
