GPU encoding settings
Oh, I've used QSVEnc by Rigaya for fastflix. That's good that Rigaya had done that then.

Optimising Handbrake for NVENC
Yeah I’ll for sure check out fastflix I think they have Nvidia AV1 although you need to add this to the settings so it can be used. Though I don’t know enough about the dual Nvenc encoders unfortunately. Though it’s worth a try to use.

4K discs that used to rip but now consistently give errors
I've been ripping my 4K movies again (to transcode them again using FastFlix, which I heard actually supports 10-bit HDR, unlike HandBrake), and I've noticed MakeMKV failed to rip a few of my 4K discs at some point, even though I had tried to clean the bottom of the disc several times. "2001: A Space Odyssey", "Back to the Future Part 3", and "Star Trek: The Motion Picture Director's Edition" started to rip but then failed. With Back to the Future 3, I remember MakeMKV saying it was a hash check failure or something similar (it was enough to make MakeMKV stop ripping it and fail).

[Question] What software would you recommend to batch convert MP4 videos to AVIF-sequence files?
If you have something reproducible and know it's an issues with FastFlix would love an issue on github https://github.com/cdgriffith/FastFlix/issues !
- GPU accelerated encoding in shutter encoder really really bad.

Can anyone point us at a windows x64 ffmpeg build with av1_qsv support working?
For GUI (shameless self plug) FastFlix wraps around it to make life easier https://github.com/cdgriffith/FastFlix
- HDR10, HDR10+, Dolby Vision with AV1?

Few AV1 questions
Well i have to recommend FastFlix as I literally coded it lol. It wraps around ffmpeg as well as Rigaya's hardware encoders (have to download and link them in settings panel).

Any recent comparison between the encoders, specially rav1e and SVT-AV1?
The docs mention that the unit for this option is in "frames" (not "seconds").

Guide to Adopting AV1 Encoding
In these tests SVT-AV1 beats x265 on quality:
- FullHD: http://compression.ru/video/codec_comparison/2022/main_repor...
- FullHD 10-bit: http://compression.ru/video/codec_comparison/2022/10_bit_rep...
- 4K: http://compression.ru/video/codec_comparison/2022/4k_report....
SVT-AV1 has seen a number of speed ups in recent releases:
-
10-bit and 4:2:2 Chroma Subsampling support for AV1?
I don't see this options under the "Advanced features" like for H.265/HEVC (for example). Also, adding "-input-depth 10" manually to the command line doesn't work (it doesn't recognize the parameter, despite it clearly being written here as one of them).

Does Handbrake publish AV1 documents?

[SVT-AV1 Git] The experimental SSIM RD tune in SVT-AV1 has been added to mainline
I find it interesting that you know the project well enough to get to the pre-compiled binaries page, yet somehow missed that the merge request explictly calls out a VMAF LOSS for the SSIM tune by several percentage points.

What's the status of AV1 encoding on ARM?
SVT-AV1 has no NEON.

My AV1 testing (Part 3)
I used the precompiled FFmpeg from SVT-AV1's git: https://gitlab.com/AOMediaCodec/SVT-AV1/-/jobs/4540276837
- SVT-AV1 1.6.0 windows x64 binaries ?
