SVT-AV1
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

Google's decision to deprecate JPEG-XL emphasizes the need for browser choice and free formats
I believe JXL's reference implementation isn't even to version 1 yet. 0.8.1 appears to be the latest. I could see them revisiting this once the reference implementation is considered complete.

Very large (DICOM) microscopy images region and resolution transcoding tiling and resolutions
I asked for this a while ago, not sure how things have progressed since then.

H.264 is magic: a technical walkthrough
That license doesn't say anything about patents. This one does: https://gitlab.com/wg1/jpeg-xl/-/blob/main/PATENTS and only says that patents owned by Google are covered. So it may be that other companies patent the technology. The information in the repository is not enough to decide whether JPEG XL is safe to use.

I am a co-creator of JPEG XL (.jxl), a new image format. AMA!
The GIMP plugin is a great thing. But it still can't open/save images with special chars in their filenames. French, German and many other languages are affected. Could this be fixed soon? https://gitlab.com/wg1/jpeg-xl/-/issues/184

Here's my googledrive of every current raw scan of my vintage 35mm slide collection of world travel and random families taken from estate sales around the world. Originally scanned 4800-6400dpi as .TIFFs but these are .jpegs. Feel free to comment your insight or download the whole thing. 2000+
https://gitlab.com/wg1/jpeg-xl/-/blob/main/doc/developing_in_windows.md It's not as straight-forward to build as it is on Linux. I'm not sure if there are official binaries somewhere, sorry.
- Improvements to the ubiquitous JPEG image format used across the internet will bring global bandwidth savings of 30 per cent, say the creators of the new technology, who have made it royalty-free.
- Is it possible to convert jxl directly to jxl?

JPEG XL website and conformance testcases published on GitHub
I'm guessing the reference implementation with complete git history is soon to follow? https://gitlab.com/wg1/jpeg-xl

JPEG XL support has been added to Firefox Nightly! (90.0a1 (2021-05-09)
The file format was 'frozen' last December: https://gitlab.com/wg1/jpeg-xl/-/tags/v0.2 Which is why FF can start implementing its usage.
