Hi Matuszewski, my apologies for not getting back to you. After you mentioned about AV1 being too slow, I had completely lost hope.
But you came through - I am grateful to you. And I am loving the new GUI options including Nvidia, AMD, Intel. I have Nvidia 40 series GPU coincidentally and its working great. Although I have noticed that the Interpolation is no longer working. When using NVenc AV1 it goes up to 'upscaled_foldername' stage -> finishes upscalling and then creates "Interpolated_upscaled_foldername" but then simply stops. I will check with other sample videos to reproduce the issue and report back.
I have one final request and I hope you please consider - Kindly include the option for selecting between 8bit and 10bit encoding.
I am a big Anime fan and I would like to encode my videos in 10bit especially to avoid any color banding issues seen in 8bit encoding.
This is the CLI syntax I have been using on my end.
-vsync cfr -c:v libsvtav1 -qp 35 -temporal_aq 1 -rc-lookahead 24 -preset 6 -svtav1-params tune=0:enable-tf=0:enable-overlays=1:enable-qm=1 -pix_fmt yuv420p10le
Here the ffmpeg pix_fmt I have set it to 'yuv420p10le'. [Alternatively (not 100% sure) as per NVenc guide we can use 'p010le']
NVEnc AV1 also supports 2 pass encoding. As an example, here is a command line from fastflix.
"C:\apps\Program Files\FastFlix\NVEncC_7.33_x64\NVEncC64.exe" --avsw --device 0 -i "D:\Video Upscale Process\Dual parallel trouble adventure\TEST\upscaled_Dual Test.mkv" --video-metadata clear --metadata clear --chapter-copy -c av1 --cqp 30 --bref-mode disabled --preset quality --tier high --lookahead 24 --aq-temporal --aq-strength 0 --level auto --chromaloc auto --colorrange auto --colormatrix bt470bg --transfer auto --colorprim auto --output-depth 10 --multipass 2pass-full --mv-precision Auto --avsync forcecfr --audio-copy 1 --audio-metadata 1?language=jpn --audio-disposition 1?default -m default_mode:infer_no_subs -o "D:\Video Upscale Process\Spirited\Encoding\Encoded\upscaled_Dual Test-fastflix-a280.mkv"
This is my humble request to make it perfect - to either provide as an option to choose between 8bit and 10bit or just change the switch in the command itself and make it default 10bit encoding.
