Full range video not preserved, reduced to Limited range. Also missing colorspace tag.

[Vrael0n]

Encoding a Full range video outputs as limited range with shifted brightness.

The range is changed to Limited (tv) and the bt2020nc colorspace tag is missing:

FFprobe Input: av1 (Main), yuv420p10le(pc, bt2020nc/bt2020/smpte2084), 3840x2160, SAR 1:1 DAR 16:9, 60 fps

NVEnc and QSVEnc don't have this behavior:

Had you tried something like this?

%~dp0\VCEEncC64.exe -i %1 -o "%~n1_processed%~x1" --codec hevc --profile main --tier high --level 6.2 --preset slow --ref 4 --ltr 3 --vbr 7000 --max-bitrate 10000 --qp-max 36 --pa sc=high,ss=high,activity-type=yuv,lookahead=41,taq=1 --colorrange auto --colormatrix auto --colorprim auto --transfer auto --chromaloc auto --max-cll copy --master-display copy --atc-sei auto --dhdr10-info copy --audio-copy --chapter-copy
pause

Difference in these 2 tags, but probably should help?
--atc-sei auto --dhdr10-info copy

Tried myself, looks fine

Frankly speaking even without HDR10 specific preset it transfers HDR10 compatability for some reason.
Also fun fact... Your sample won't even decode with --avhw set on my RX 6750XT. Only default to --avsw.

UPD: My bad. I hadn't noticed that video actually got clamped to limited, as i focused on colorspace instead.

[DimkaTsv]

Tried to simplify command to look more like yours. And also made it HEVC_10, not that it is necessary for HDR videos.

UPD: My bad. I hadn't noticed that video actually got clamped to limited, as i focused on colorspace instead.

[rigaya]

I have tried adding colormatrix and fullrange flag also for AV1 encoding in VCEEnc 8.17.

[Vrael0n]

Confirmed fixed in 8.17, range and matrix are now matching source video.
