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.

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.

A way to check quality of videos
https://github.com/fifonik/FFMetrics is a good place to start.
- Need some PRO help (AV1 vs x264 questions+how to calculate transparent constant quality)

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).
- Why preset 8 and 13 are better than the other using svt-av1 with crf 5 ?

[Epos Vox] Intel AV1 vs X264 vs NVENC/AMF/QSV hardware encoder comparison
https://github.com/fifonik/FFMetrics is a gui to compare your own outputs if you're too lazy to learn the cli for a bunch of different programs.

CRF value for efficient 4k encoding?
I recommend you do some tests I'd your own with FFMetrics.

On Export, Left audio is delayed by about half a second, is there a fix?
https://handbrake.fr/ its very easy to use.

Linux GUI/Frontend for VMAF
nothing actually, i just mentioned it as an encoding frontend.
- Windows Photos saves really large video files
-
Vegas PRO18, my mov files.
At this point, use https://handbrake.fr/ to transcode into a higher res MP4 and use as proxy footage,

converting .avi files to .mp4
Maybe you could try HandBrake.
