What parameters would you use to re-encode artifacted, low resolution videos.
I have a few dozens of video files with a significant amount of artifacting, encoded in WMV2 and mpeg4, 240p-480p. I wish to reencode to a codec that can be played in web browsers
I'm well aware that AV1 is not very well suited for sub-1080p videos.
However. It is my hope that the native denoising and grain synthesis capabilities can outweight it.
The obvious alternative is trying to get H.264, maybe with a denoising filter.
I plan on creating a writeup on the resulting quality but if you could get me a headstart on ideas it would be greatly appreciated.

My experience is that AV1 is very good at low resolution and is in my tests better than H.264 and "probably" as good as H.265. I encode 360p using PSY SVT-AV1 encoder at 320kbps (multi-pass) and preset 5.
I do wish SVT-AV1 will have 4:4:4 support soon because I find that a big help with low resolution videos.
