Another encoder for AV1, but not only. It has many features including multithreading, which is one of the biggest problems of AV1. It looks very interesting:
Cross-platform command-line AV1 / VP9 / HEVC / H264 encoding framework with per scene quality encoding
By the way, av1an also uses an algorithm developed by Netflix. It is already included in ffmpeg, but you have to enable it.
Perceptual video quality assessment based on multi-method fusion.
Does anyone know and use these projects?
I read some of the information, but I could not find anything that said that:

It would be good to have a new encoder for AV1, because the standard is quite slow. I dont think its easy to implement it, though?
EDIT:
It seems that the ffmpeg provided by Arch linux already implements vmaf.
