The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

How do you guys visually compare clips?
FFMetrics.

How much film grain synthesis is too much?
You mean this? But he seems to be using a 4.x version of FFmpeg. That's ancient history at this point, since 4.0 was released in 2018, and 5.0 and 6.0 have been released since. And the dav1d in his FFmpeg build is 2+ years old as well, which means it's even pre-1.0. No wonder basic shit doesn't work.

If I were to use Infuse to access a Jellyfin server on my ios devices, can it do a transcoded or optimized download (similar to Plex’s sync feature) so I can watch offline?
You could then use applications such as HandBrake (encoding) and FFmetrics (VMAF), or better ShutterEncoder (supports both encoding and VMAF) to first encode a few test clips and then calculate the VMAF score. Anything above 95% will be visually lossless in motion. 93% is lossless to many people too (not to me though) and 90% is about the quality you get on YouTube - so absolutely terrible. If you ever want to generate an FFmpeg encoding command, FastFlix is also nice.

R9 3900X struggles to play 4K 10bit AV1
Someone tried your suggestions and apparently, at least with the current FFmpeg versions, the flag doesn't affect VMAF (see here). I can only conclude VMAF does already return the highest values possible with AV1 as is, though what you said made a lot of sense so am unsure where exactly something changed from you gaining your knowledge to the current state of VMAF in FFmpeg (I'm a little puzzled).

CRF value for efficient 4k encoding?
I recommend you do some tests I'd your own with FFMetrics.
What are some alternatives?
When comparing nmkoder and FFMetrics you can also consider the following projects:
