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.

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

Automatic choose encode settings?
Basically Av1an.
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.

VMAF is confusing me
Have you seen Av1an? It's supposed to encode to a target VMAF.

AV1 Encoder development series Part 1: working on rav1e in a different, better and more forward manner
Here's a couple of pages that cover the basics of aomenc: https://github.com/master-of-zen/Av1an/blob/master/docs/Encoders/aomenc.md https://gist.github.com/shssoichiro/a46ff01db70243c1719479f6518ea34d For more of a deep dive into settings, you can join the discord, lots of people share their settings and you can see what's working well for others.

Should I recompress video I shot with mobile?
Av1an can even aim for a target quality.
-
did I fail at preserving dvds? mpeg2 vs h264 vs av1
I like using NotEnoughAV1Encodes. There's also Av1an, and ab-av1.
-
Currently impossible to use av1an on Windows?
In your case, I'd get one of the [nightly builds](https://github.com/master-of-zen/Av1an/releases/tag/latest) of Av1an. They should work with ffmpeg 5.

Hi, i have recently switched from HEVC to AV1 due to lack of support on devices. First time encoding a movie. It says something like 110 hours to finish encodeโฆ is this normal? . specs are as follows: handbrake: apple M1 16gb ram software encode using handbrake 1080p slow preset 8.5mbps
If you really want to try encoding directly with the encoders(which will allow you to update them separately), there is nmkoder: https://github.com/n00mkrad/nmkoder/releases
-
Getting started with av1
Handbrake has AV1 options in the nightly releases. There are lots of encoders that wrap FFmpeg into a GUI such as Fastflix, nmkoder, qencoder, or Not Enough AV1 Encoders.
-
AV1 encoding using StaxRip
I believe it's been mentioned already, but nmkoder is fantastic. I use it on Linux using WINE & it works flawlessly there as well
-
Why is there a big lag when I scrub my AV1 videos encoded by `libaom-av1`?
Check out my GUI Nmkoder if you don't like the command line program.
-
Quickest way to recode just audio?
refer to this https://github.com/n00mkrad/nmkoder/releases/tag/v1.8.0
Use ffmpeg or my GUI Nmkoder.
