AMF AV1 + 10 BIT HDR
Is the rdna 3 encoder capable of doing 10 bit using AV1? I believe it can with HEVC. Thanks for taking the time to read/answer!
Your answer is yes, AV1 10 bit is supported Here is example.
C:\Users\-----\Videos\test sample>C:\Users\-----\Desktop\Utilites\VCE_Encoder\VCEEncC_x64\\VCEEncC64.exe -i "C:\Users\-----\Videos\test sample\Test_softer.mkv" -o "Test_softer_processed.mkv" --codec av1 --profile main --level 6 --preset slower --output-depth 10 --ref 4 --ltr 3 --vbr 10000 --max-bitrate 15000 --qp-max 36 --pe --vbaq --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 --log vceencc_log.txt --log-level info

avvce/avsw: --dhdr10-info copy is only supported with sw deocde in VCEEnc, switching to --avsw.

Sadly, only one small downside is that preanalysis is not available for 10 bit. Only preencode. But there is small chance that it will be added later from what i understand?
Another limit is 6.0 encoder level... but, surprisingly it does not limit you from encoding 8k60 videos... I guess it is because general HW is here, but only max potential sample rate, decode rate and bandwidth are limited... Doesn't stop you from encoding under these limits?. Also heh, 8k60 video from YT that takes 794 MB transcoded into 4.24 GB monstrosity. But for some reason YT video stutters, while transcoded one is smooth as ice (both are 8k60 AV1 videos). [Hmm, i guess i could've lowered max-qp to 38... ] [EDIT: Correcting my mistake from lack of experience. As AV1 QP range is 0-255, then i should've lowered max-qp to something around 70-100, i think?]
[Also don't blindly copy what command i used. Transcoding speed is not very nice, only 28.6 FPS (avg 60 FPS on fast preset)... On other hand, it is actually quite fast for whatever i thrown under bus in terms of parameters]
10-bit AV1 encoding is supported on RDNA 3 according to the Wiki page for GPU and APU HW Features and Support
PreAnalysis is not available for 10-bit.
