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.

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
-
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.
-
AV1 encoding using StaxRip
I believe it's been mentioned already, but nmkoder is fantastic. I use it on Linux using WINE & it works flawlessly there as well
-
Why is there a big lag when I scrub my AV1 videos encoded by `libaom-av1`?
Check out my GUI Nmkoder if you don't like the command line program.
-
Quickest way to recode just audio?
refer to this https://github.com/n00mkrad/nmkoder/releases/tag/v1.8.0
Use ffmpeg or my GUI Nmkoder.

How do you guys visually compare clips?
FFMetrics.
I'm still new to all this but two programs I've come across are FFMetrics and MSU Quality Measurement Tool. Both are free too.

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.

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).

[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.

How to compare video quality?
i like FFmetrics (https://github.com/fifonik/FFMetrics, but only for pc)

Video Comparison Tool
Sidenote, you won't get an "real" answer by just visually inspecting them. There are tools like https://github.com/JNoDuq/videobench and https://github.com/fifonik/FFMetrics which makes running tests easy and boils quality down to number.
What are some alternatives?
video-quality-metrics - Test specified presets/CRF values for the x264 or x265 encoder. Compares VMAF/SSIM/PSNR numerically & via graphs.
FastFlix - FastFlix is a free GUI for HEVC and AV1 encoding, GIF/WebP/AVIF creation, and more!
Av1an - Cross-platform command-line AV1 / VP9 / HEVC / H264 encoding framework with per scene quality encoding
mkvtools - bash tools for working with mkv files
videobench - VMAF PSNR Bitrate Analyzer
NotEnoughAV1Encodes - GUI for AV1 (aomenc, rav1e & svt-av1)
vmaf - Perceptual video quality assessment based on multi-method fusion.
QSVEnc - QSVによる高速エンコードの性能実験
video-compare - Split screen video comparison tool using FFmpeg and SDL2
