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.

Is there a software that accurately measures and compres video quality?
What you want is vmaf. ffmpeg let's you calculate a vmaf score for any video you'd like, if you want a gui to do this a bit more comfortably, i have used nmkoder in the past

Best FFMPEG GUI implementations?
Adding link to our friend /u/nmkd from this parish. https://github.com/n00mkrad/nmkoder.
- Is there an option in ffmpeg that will report the largest actual non-black picture size in a video that has black borders?

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 encode… 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

PMS: Optimizer/transcoder unnecessarily transcodes video when transcoding FLAC > AAC audio
workaround: i used nmkoder to transcode the audio to AAC 256 (left video alone), and the resultant file direct played just fine. i think this should prove that the error i get above is bogus(?)
- av1an and portability (windows) ??

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.

Best way to reduce MKV file sizes and convert audio?

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

I have a feeling crunchyroll should be using AV1
I specifically used https://github.com/master-of-zen/Av1an with --target-quality 100 to keep the compression as close to lossless as possible (you could probably shave even more size off if you didn’t use near-lossless compression)
-
Automatic choose encode settings?
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.

Building pc for ffmpeg rendering
i'm still trying to figure out if av1an is the breakthrough to using large CPU counts without losing quality. but it's a ridiculously poorly documented program. i haven't gotten it to run effectively yet. https://github.com/master-of-zen/Av1an

Codecs for the 4K Era: HEVC, AV1, VVC and Beyond
I don't know about VVC, but I've never seen a recommendation of preset 0 for SVT-AV1. The docs say "presets 1-3 represent extremely high efficiency, for use when encode time is not important and quality/size of the resulting video file is critical". It seems like 0 is the equivalent placebo preset. But if you want AV1 with coding efficiency over all else, IIRC the typical approach is to use av1an to detect scene transitions and farm out parallel encodes with aomenc.
-
Automating av1 encoding?
That might be because it doesn't work.
-
VMAF is confusing me
Have you seen Av1an? It's supposed to encode to a target VMAF.
