 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
