AV1 UHD HDR10, not possible to encode on Intel ARC?

[VisionHDR]

Hello,

I'm experiencing some issues on Intel ARC Mobile (Asus ZenBook 14 2024) this laptop is able to encode same as desktop Intel ARC's any AV1 command (as far as i know).

I was able to encode perfectly fine a UHD HDR10 with ffmpeg's qsv_av1, so I'm wondering why this isn't possible with QSVencC64 using similar/same settings?

What are the settings to use to encode a video to proper HDR10 with QSVEncC64? when i try to add a --colormatrix --transfer --colorspace to HDR10 specs i get error.

Even with a minimal command just setting the colormatrix to bt2020nc without the transfer, colorspace and metadata, like this:

QSVEncC64.exe --avsw -i "C:\AV1_testing\ProRes_4444XQ_HDR10.mkv" -o AV1_output_test.mkv --codec av1 --profile high (or main) --colormatrix bt2020nc

output_av1.mkv

MFXENCODE: Failed to get required buffer size for MFXENCODE: invalid video parameters.
allocD3D11: QSVAllocator: Failed CheckRequestType: undeveloped feature.
INPUT: allocWorkSurfaces: Failed to allocate frames: undeveloped feature..
AllocFrames: Failed to allocate frames for INPUT-MFXENCODE: undeveloped feature..

QSVEncC.exe finished with error!

Is AV1 currently working for HDR encoding in QSVEncC64? Thanks.

--colormatrix --transfer --colorspace does work with AV1 encoding on my system with Arc A380, when input is HEVC HDR10.

However I have never tested ProRes 4444XQ HDR10 so that might be causing error. Will it be possible to have a small test sample file which contains ProRes 4444XQ HDR10 format?

Hello, sure you can get a sample ProRes 4444XQ HDR10 here:

Please ask access with a gmail account (i will only accept yours)

It's not exactly "HDR10" since this is a ProRes 4444XQ (12-bit Full Range), but to make me understand better what i use.

It should work as with NvEncC64 (that encodes these using --avsw) but it fails to do it here with AV1 and QSVEncC64.

Thanks.

Thank you for the sample file, I have requested access from rigaya34589 mail account.

QSVEnc should also work with --avsw, but there might be something wrong handling YUV444 12bit.

Thank you for the file. By removing --profile high, you shall be able to encode fine.

I'll close this issue, as the solution has been presented.
