hello guys,
At the moment I'm restoring some cartoon episode captures which aren't my own and suffer from many problems.
(sadly there is no chance the owner will recapture it or switch to more descent equipment)

This is the raw capture

This is my remaster. https://workupload.com/file/kxv8XG9Zd3H

FFVideoSource("T:\TV-VHS\Geffen.avs.mov")
ConvertToYUY2(interlaced=true)
KillPulse(times=4, motion=10, complex=20, complex2=20, mode=0)
ConvertToYV12(interlaced=true)
AnimeIVTC(mode=1,bbob=4, cbob=4, precision=4,aa=4)
TemporalDegrain2(degrainTR=1, grainLevel=2, postFFT=0, postTR=1, postSigma=1.0, postDither=-1, postMix=0, extraSharp=false, fftThreads=1, debug=false)


I also did some slight color boost and some brightness enhancement in davinci resolve as well as fixing some stabilisation problems. Kill pulse removed those white spots pretty good and that "new" temporaldegrain2 does wonders without killing all details.
I still have to do some fixing on the Chroma Bleeding this shouldn'T be much of a problem. The main problem which I couldn't get rid of are those black shadows, staints, smudge mostly visible if you take a look at the faces.

I didn't find anything how to get rid of those. Maybe you have an idea?
thanks a lot

you can read those (with replies) https://forum.doom9.org/showthread.php?p=1715113 and https://forum.doom9.org/showthread.php?p=1728274

there are no perfect fix though (at least not yet or I didn't find it)
