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.
- How do you guys visually compare clips?

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

HandBrake 1.7.0 – The open source video transcoder
Its literally a feature of all the underlying encoders. And you can do it even with exotic ffmpeg/vapoursynth filter chains. So I can't imagine why.
TBH I would just recommend Staxrip if you are on Windows: https://github.com/staxrip/staxrip
There is a linux equivalent, I can't remember what its called.
Or maybe some av1an GUI for Mac/Linux. All of these things support a target file size with many more features.
- FFmpeg is getting better with multithreaded transcoding pipelines

Ffmprovisr – Making FFmpeg Easier
Since ffmpeg CLI still makes me pull ny hair out, I am going to plug vapoursynth:
https://www.vapoursynth.com/
Its Pythonic video filters... But also so much more: https://vsdb.top/
And Staxrip, which makes such good use of ffmpeg, vapoursynth, and dozens of other encoders and tools that I reboot from linux to Windows just to use it: https://github.com/staxrip/staxrip

How to install Av1an on Windows 10 x64 ?
https://github.com/staxrip/staxrip GUI But av1 outdated a bit which could be replaced/rebuild https://github.com/m-ab-s/media-autobuild_suite

How I archive miniDV tapes - a short guide
2-4: I use StaxRip to encode the video because it includes the QTGMC deinterlacer, which is from my research a very good deinterlacer that produces less artifacts in the video than other deinterlacers like the one included in HandBrake.

Intel A380 performance - advice wanted!
But I actually got through it and found a great solution for myself using StaxRip and an updated QSVEnc by Rigaya. Replace StaxRip's outdated QSVEnc with the updated Rigaya QSVEnc.
