May be whole thing is really not supported onWindows (!) in Free version,
but  there was workaround posted that may be fix it for HEVC (x265) encoded
files:

====
Yes, try DNxHR which should be flagged properly and YT should detect HDR
nature of the file.

You can "fix" those files with ffmpeg:
Code: Select all
<https://forum.blackmagicdesign.com/viewtopic.php?f=21&t=212751#>fmpeg.exe
-i C:\TestAsHDR.mp4 -bsf:v
hevc_metadata=transfer_characteristics=16:colour_primaries=9:matrix_coefficients=9
-c copy  -movflags +write_colr C:\out.mov

This will add PQ flagging to your file.

Other solution is exporting to eg. DNxHR and encoding to h265 though 3rd
party- ffmpeg, etc.

interesting to note that even just 6 month ago whole HDR situation was ...
still a bit of mess ;)
