Comment (by Ulysse Dansin):
Replying to [comment:6 Balling]:
> BTW, who produces such bad files, looks like you use ffmpeg too? There
is only one player that supports constant luminance like that (mpv) and
even then bt.2020-cl is not supported with pq transfer. I saw it on 8k
sattelites but even there sdr [transfer] was used.
Us :) We were investigating the behavior of colr box with different inputs
when we saw the mismatch between colr box and NAL SPS for one of our QA
tests... Our current encodes are using bt.2020-ncl with ST2084. Thanks so
much for your help!
