FFmpeg 6.0
It exists only as a patch from Intel (https://github.com/intel/cartwheel-ffmpeg/blob/master/patche...) but I haven't seen any efforts to upstream it yet.
-
Trouble with FFmpeg using quicksync: Encoded files are taking a long time to play again when e.g. changing position or skipping forwards/backwards during playback (Linux, Intel Arc A380)
So I'd think that this might be a bug, possibly due to the more or less alpha status of support for the Intel Arc on Linux. But I don't know from where it got introduced, most likely the Intel Arc specific Mesa Driver or a patch gone wrong from cartwheel-ffmpeg.

Nvidia AV1 Encoding Support / 8th Gen (Ada Lovelace) NVENC
Anyway, the initial reviews are out so I'm not in a massive rush. It would just be nice to have Nvidia AV1 support added. (I had to use Intel's own Cartwheel branch to get AV1 support with Arc, but at least I had that option.)

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
