Avisynth - correct defects caused by sharp

[byme]

in first, sorry for my english

the defect is as follows



is a kind of over-sharp, even though in reality it is not overly sharp video, but still noticeable artifacts

I had read on doom9.org, if I remember correctly, that the AnimeIVTC (but I could remember being ill and another filter), was itself a function that might be something for me, but I do not remember what it was
I found the problem .. and that did not allow me to use the AnimeIVTC, was that he did not accept video at 50 fps

antialiasing filters do not like, because round the edges too ... then try an alternative
and then correct a defect of this kind with an anti-aliasing does not seem the right way

the doom9.org is offline for several days. Not being able to see it so I turn to you ..... Can you help me?

You're convinced they're sharpening artifacts and not bobbing artifacts or low bitrate artifacts?

I don't see that you have any choice but to antialias it. Either that or go back to your original source and start all over again. What, you downloaded this and don't have the source? Maybe try this:

QTGMC( Preset="Medium", InputType=1 )

yes, they look like low bitrate artifacts to me (not your typical oversharpening halos/ringing)

[byme]

no, I do not have the source

for what I know it is caused by an over-sharp, or else by a sharp incorrect

The opposite of sharp is blur. But you have a combination of over compression, over sharpening, and too much noise reduction.

To me it looks like some sharpening was attempted on a low bitrate source in a restoration effort.

If it is indeed sharpening artifacts, you could try aWarpSharp() from AviSynth. It's a filter optimized for cartoons, but oversharpening to me applies since it does give off a cartoony effect IMO.

Defaults of aWarpSharp() are depth=16 and blurlevel=2, with ranges of 0-64 and 1-4 respectively if you want to try different combinations on the source. I like aWarpSharp(depth=6,blurlevel=1), but this is dependent on Source and is highly subjective.
