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.
