Plots

Distortion as a function of bitrate

mendevi plot '<colorspace.db>' -x rate -y psnr -c transfer -m '(primaries, range)' -f 'codec!="ffv1" and name=="park_joy"'

Reproduce

mendevi prepare park_joy.mp4 -p fhd
for prim in bt601 bt709 bt2020
do
    for trans in linear gamma22 gamma28 smpte170m smpte2084 log316
    do
        mendevi prepare park_joy.mp4 -p fhd --primaries $prim --transfer $trans --range tv
        mendevi prepare park_joy.mp4 -p fhd --primaries $prim --transfer $trans --range pc
    done
done
