hdr2sdr colorprim ignored

[holmy88]

colorprim setting is being ignored when using hdr2sdr and is always doing bt2020:bt709 when I'm trying to use st432-1:bt709. This was fixed up in nvencc last year if that solution can be duplicated.

Thank you for letting me know the issue, QSVEnc 7.39 has ported fix from NVEncC.

Just tried it, colorprim setting still being ignored and doing bt2020:bt709 instead. My full command below

"C:\Temp\bin\encc\qsvencc64.exe" --avhw -i "C:\Temp\Thread1\video_in.mkv" --avsync forcecfr --crop 0,276,0,276 --codec hevc --output-depth 10 --quality 1 --qvbr 17800k --qvbr-quality 20 --fallback-rc --max-bitrate 19580k --vbv-bufsize 17800k --la-depth 100 --gop-len 50 --hyper-mode adaptive --i-adapt --b-adapt --adapt-ref --adapt-ltr --b-pyramid --tskip --sao none --vpp-colorspace hdr2sdr=reinhard,source_peak=10000,peak=4000,desat_strength=1,colorprim=st432-1:bt709,matrix=bt2020nc:bt709,transfer=smpte2084:bt709 --colormatrix bt709 --colorprim bt709 --transfer bt709 --colorrange limited -o "C:\Temp\Thread1\video_out.mkv"

The problem was the handling of colorprim when using hdr2sdr. QSVEnc 7.40 should have fixed this issue.

Just tested with my script, I can confirm it is now working. Thank you.

I'll close this issue, as the problem should have been fixed.
