 > Forcing scale actually does not work. OOPSIE


 Now it works again, strange stuff (no need to force color range to pc,
 btw, but I did not check)... new option out_chroma_loc also needs to be
 set to center, I did not check what happens

 ffmpeg.exe -i "this one does it.mp4" -vf scale=out_color_matrix=smpte170m
 -frames:v 1 -q:v 1 -f md5 -

 But there is obviously a need to force range when just doing md5:

 ffmpeg.exe -i "this one does it.mp4" -vf scale=out_color_matrix=smpte170m
 -frames:v 1 -q:v 1 3182821211.jpg
