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.

What's the best source/course to learn AV1 encoding with all it's parameters?
GitHub :: Advanced Command Line Options

AV1 Video Codec
cpu-used is (somewhat confusingly) not for how many threads it uses, but how good the quality of the video should be in a scale from 0 to 9, where 0 is best quality and slowest, and 9 is worst quality and fastest. Very similar to how -preset was used for x264.
https://github.com/AOMediaCodec/community/wiki#how-to-make-e... explains the different settings that most change the speed of encoding.

Converting big video library with av1
I wrote a little script that uses ffmpeg with settings similar to those in the guide, and then another ffmpeg run to extract the subtitles as vtt. I would be happy to share more of my settings if you are interested. Of course, your needs and mine may differ.
- No library usage documentation for SVT-AV1?
- AOM or SVT-AV1 on 5950X? video is 8K 60fps 60Mbit/s

SVT-AV1 HDR Encoding (libsvtav1 with ffmpeg)
How about use the parameter "HighDynamicRangeInput" with command line "--enable-hdr 1"? It's from the official page: https://github.com/AOMediaCodec/SVT-AV1/blob/master/Docs/Parameters.md
- Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder)
- AV1 Video Codec
- Seems like the SVT-AV1 documentation issue #1753 about missing presets explanation is fixed now. And it seems like the preset 0, 1 and 2 are the same thing. Plus tons of other useful encoding guidelines (like how to tune for animation etc.).
