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?

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.

Why is my video so pixelated after putting through handbrake? I thought my settings were fine.
As mentioned those are different frames you are testing. Personally I use veryslow but most people here don't spend as much time encoding a single item as I do. Also don't use PNGs for checking use Video Compare . You can run two different MKVs at the same time and compare them frame by frame both in playback and pausing them.

Compare different models
use the Video-Compare tool. watch the demo here how it works

How do you guys visually compare clips?
https://github.com/pixop/video-compare This one is simple but really good

Is FFmpeg able to convert DVD iso to a set of mp4/mkv?
Well, I would use https://github.com/pixop/video-compare for that - it's the tool I normally use to compare videos (to find differences or to check image compression issues) but it can load the same video twice to watch it frame by frame. It even shows the type of frame I'm on so it's useful when I need to find a keyframe to do a video split with no recoding.

Downsides of fractional scaling
You can preview (export as preview) test of few presets, settings, etc. on TVAI and if you wish you could also use a compare tool to check the results to see for yourself if you notice any difference between them (that would save you tons of time). or just playback the 2s / 5s of the preview(s) you generate, right after the other to see if you spot any difference in quality.

Unusually good compression ratio - Sanity Check
If you need to compare images easily, consider slow.pics. Or ICAT, or Video Comparison Tool. And actually, even x264 and x265 don't have perfect CRF scales as well, they are offset by a constant iirc.

Can't trim a MKV file accurately without re-encoding?
You can easily check the type of each frame with the use of https://github.com/pixop/video-compare/ software - just use the same video twice (as video-compare needs two video inputs) and look for I, B, P letters near the current frame time.
- Hello friends! Which youtube download video type is higher quality? MKV 720p AV1? Or MP4 1080p? See pic below! -Thanks!
