Extreme Video Compression
Netflix did VMAF for this: https://github.com/Netflix/vmaf
It checks a reference video against an encoded video and returns a score representing how close the encoded video appears to the original from a human perspective.

Linux GUI/Frontend for VMAF
Not sure this is the right sub but I'm going to encode my entire BluRay collection in AV1 / NVEC. I'd like to optimize settings with VMAF but would like an ubuntu/debian based GUI to work with.

reduce video filesize
Netflix even has a method to measure perceivable quality difference. A little while ago I used this tool to calculate this.

Unusually good compression ratio - Sanity Check
You can try VMAF as well (which ffmpeg supports). It's normally recommended to make a lossless copy first as a baseline too

Hello friends! Which youtube download video type is higher quality? MKV 720p AV1? Or MP4 1080p? See pic below! -Thanks!
Netflix has released vmaf https://github.com/Netflix/vmaf to compare video quality
-
Is there a way to tell which file is higher quality without a 'source' file?
The only FOSS no-reference metric I know of is CAMBI, which is used for measuring banding. Unfortunately it's not usable via FFmpeg, only from the vmaf executable (or programmatically with the library), and the executable only accepts raw video as input, which isn't very practical for long videos. See https://github.com/Netflix/vmaf/blob/master/resource/doc/cambi.md for usage.

Dav1d, fast AV1 decoder, version 1.0.0 released
I was like wtf is vmaf?!
Turns out it's $NFLXs OSS automated encoding quality assessment tool. Pretty cool!

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.
