Hi all,

I am trying to transcode some HDR10 videos into other format. One of the video is https://4kmedia.org/sony-mont-blanc-hdr-uhd-4k-demo/.

This video was discussed https://forum.videohelp.com/threads/393092-HDR10-not-working.

Ok, so my question is the master-display metadata is:
Code:
Color primaries                          : BT.2020
Transfer characteristics                 : PQ
Matrix coefficients                      : BT.2020 non-constant
Mastering display color primaries        : R: x=1.000000 y=1.000000, G: x=1.000000 y=1.000000, B: x=1.000000 y=1.000000, White point: x=1.000000 y=1.000000
Mastering display luminance              : min: 0.1000 cd/m2, max: 0.5000 cd/m2
Codec configuration box                  : hvcC
The mastering display color primaries and mastering display luminance doesn't made sense to me. However, I was able to display this video properly with PotPlayer.
In this case, I am confused, why is this video displayed properly with wrong metadata? If I need to transcode, should I "guess" the metadata (like dci p3)? Or leave it as is?

Thanks!
