There are a dozen denoisers in ffmpeg, no idea which one is best/good. One possibility would be --vf=lavfi=[hqdn3d], or --vf=lavfi=[removegrain], or ... You can also assign this to a key and toggle it by using that key: a vf toggle "lavfi=[hqdn3d]"

im getting this [ffmpeg] Impossible to convert between the formats supported by the filter 'src' and the filter 'auto_scaler_0' [lavfi] Can't configure libavfilter graph. wit this : a vf toggle "lavfi=[hqdn3d]" I get /Users/ss/.config/mpv/mpv.conf:36: unparseable extra characters: 'vf toggle "lavfi=[hqdn3d]"'

Naturally, key bindings do not go to mpv.conf. https://mpv.io/manual/master/#files

lavfi is just not working. no matter what I try. Im using mpv 0.27.2 hombrew edition

You need to disable hwdec for these filters, or use hwdec=auto-copy.
