In my old CS4 version of PS I can record an action consisting of several steps including denoise, despeckle or dust&scratch filters and then via automate/batch convert apply it on the files in a folder copied from the render history of Cheetah.I'm trying with 30 samples but it's a little noisy.
I don't think PS has any video filters and denoise is only single frame at a time.
Don't know that either, sorry, that's why I use automate / batch conversion of the single frame files in the Cheetah render history.I tried to make an action in PS to denoise and advance frame and
repeat until the end but I couldn't figure out the repeat part.
