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.

Does anybody run libvmaf on your output as a validation check?
VMAF for anybody that doesn't know quantifies the quality difference between a source and modified video.

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

How did my silly little After Effects filter reduce the file to 10% its size? The footage wasn't raw or 10-bit or anything, and I rendered it out at basically the same resolution (cropping aside). How did I do this????
Well you can use something like https://mediaarea.net/en/MediaInfo to look at the files and https://github.com/Netflix/vmaf to see if there is no loss.

4:2:0 10-bit HEVC vs 4:2:2 10-bit AVC codecs higher quality? (S5II, GH6)
You can try some tests https://github.com/Netflix/vmaf

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

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.
