AV1 CRF default?
(lemmy.world)
It really depends on the encoder, but it seems 18~20 is good for SVT-AV1.
The default is 35. My rule is to use 4 points greater value than the CRF of x265. However, AV1 isn't good with fine details, so consider using lower CRF accordingly if compression isn't affected by it much.
