I thought that chingu made HDR screnshot but tagged jpeg as SDR, spent some time trying to convert to SDR manually
-vf pad=h=1700,zscale=tin=2020_10:min=2020_ncl:pin=2020:t=709:m=709:p=709:npl=600
-vf pad=h=1700,zscale=tin=2020_10:min=2020_ncl:pin=2020:t=linear:m=2020_ncl:p=2020:npl=100,format=gbrpf32le,tonemap=tonemap=hable:desat=0,zscale=t=709:m=709:p=709,format=yuv420p
still looks wrong tbh
