Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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).

Guide to Adopting AV1 Encoding
The hardware encoders are very fast and generally better than x264 (but not by as much as you'd think with the x264 slow preset).
In addition, there are threaded AV1 encoders you may be overlooking, like SVT-AV1. For non-realtime, my favorite is av1an, which also yields better quality than is possible from aomenc: https://github.com/master-of-zen/Av1an

I have a feeling crunchyroll should be using AV1
I specifically used https://github.com/master-of-zen/Av1an with --target-quality 100 to keep the compression as close to lossless as possible (you could probably shave even more size off if you didn’t use near-lossless compression)
-
Automatic choose encode settings?
There's also Av1an as suggested by someone else. It's going to produce more efficient encodes because it uses chunk-based encoding to reach the required VMAF for every single chunk, but this is also slower because every chunk will be re-encoded until the VMAF target is reached. It's also a PITA to compile, has a long list of bugs, and isn't very actively developed. One of the long-standing issues is that frames have a tendency to go missing during splitting, which IME is going to keep happening when the input files aren't standardized. And thus the recommendation is to transcode the input to lossless first, which is just completely unsustainable.

Building pc for ffmpeg rendering
i'm still trying to figure out if av1an is the breakthrough to using large CPU counts without losing quality. but it's a ridiculously poorly documented program. i haven't gotten it to run effectively yet. https://github.com/master-of-zen/Av1an

Codecs for the 4K Era: HEVC, AV1, VVC and Beyond
I don't know about VVC, but I've never seen a recommendation of preset 0 for SVT-AV1. The docs say "presets 1-3 represent extremely high efficiency, for use when encode time is not important and quality/size of the resulting video file is critical". It seems like 0 is the equivalent placebo preset. But if you want AV1 with coding efficiency over all else, IIRC the typical approach is to use av1an to detect scene transitions and farm out parallel encodes with aomenc.

Automating av1 encoding?
That might be because it doesn't work.
-
VMAF is confusing me
Have you seen Av1an? It's supposed to encode to a target VMAF.
