@sjw @iska @p hevc and svt-av1 are still pretty slow. they have a lot more filters to work with so trialing the combinations of filters is quite onerous.

i think it will remain this way until neural heuristics become a commonplace thing. there was one paper about a chinese codec (i forgar the paper) where they did this and it does work fine.

basically using the slow encoders to brute force reference material and then training neural networks to predict filter chains directly, it does make these things a lot more performant.
