But admit this boost is only seen in 'an obscure filter'.

I wish they made a 100x leap to the AV1 encoder. Even on my 12900k it runs at like 0.001x real time, which is... well, unusably slow.

    Are you using 'libaom-av1' or 'libsvtav1'? Libaom-av1 is very known for being very slow.

    I was under the impression that libsvtav1 was still underdeveloped, but turns out the ffmpeg documentation for it was just lacking. Looks to be pretty good quality and even supports two-pass (which the documentation doesn't mention).
