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.

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

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.).

SVT-HEVC - SVT HEVC encoder. Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel® Xeon® processors. Using the open source SVT-HEVC encoder, it is possible to spread video encoding processing across multiple Intel® Xeon® processors to achieve a real advantage of processing efficiency.
aom-av1-lavish - A fork of aom-av1-psy, which is a fork of aomenc. Designed to open up the encoder for hyper-tuning and fidelity.
