Comment (by Balling):
"note that input file clearly says range PC in both cases"
What? You forced it to be PC, also known as full range. If you want
limited -vf scale=in_range=tv:out_range=pc, if you want limited output -vf
scale=in_range=tv:out_range=tv
If you want limited output but input is full range -vf
scale=in_range=pc:out_range=tv
Same for the other 4 parameters (chroma siting (also known as chroma
position or latice), primaries (also known as gamut), color matrix (also
known as colorspace), transfer (also known as gamma, EOTF)), each produces
different pixels, and each can use a different dither, dufferent upscale
algorithm, different scaling algorithm, transfer aware resizing and also
accurate_rnd stuff!
Just use zscale, I am begging you.
