Ffmpeg AV1 is a fantastic codec. Open and promising a better compression ratio than HEVC / AVC.
However I am unclear right now about the possible CRF settings.
x264 defaults to a CRF of 23 x265 defaults to a CRF to 28
These two seem to have a similar visual quality for me.
What is the corresponding CRF for AV1 – what CRF has a similar quality and what is the default?
Please excuse if this question was asked before. I googled and searched reddit. However I only found complicated answers wits PSNR etc but no simply estimate answer.

I’m trying a 1080 bluray rip I did at crf 30. I read somewhere that I should using preset 4.1 and between 28 and 35 for 1080… I’ll let you how how it comes out in 15 hours lol.
