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.

Motion detection from video compression
look for libraries to extract motion vector from video streams. e.g. https://github.com/vadimkantorov/mpegflow or https://github.com/jishnujayakumar/MV-Tractus

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 ?
What are some alternatives?
