Problem with chroma in edges

Hello all,

This is my first thread. I have a problem with chroma that stand out evenly to the edges of anime figures, and the traditional method of move chroma not work, because if you move to one side, the problem intensifies the opposite side.

Here is a image:



Look at the head of both characters and color as mustard excels.

I hope everyone's help. Thank you.

Thanks for responding Vitaliy Gorbatenko.

The problem is not ghosting or haloing, but chroma . Thanks anyway.

greyscale()

It looks like it's been overdenoised , and chroma over smoothed



mergechroma(awarpsharp2(depth=40)) #or some other settings

MergeChroma(aWarpSharp2(chroma=4))

chroma: 0..4
Processing mode for chroma planes (U and V):
0 - fill with zeroes
1 - don't care, default for aSobel and aBlur
2 - copy
3 - process
4 - guide by luma - aWarpSharp and aWarp only, default for them

With MergeChroma (Awarpsharp (Chroma = 4)) using it 2 times at the beginning of the script improves the image. Here the comparison:

Original:



Corrected:



I do not know if I can be another way to further improve the image.

I did try:

Code:
Clip
ConvertToYUY2()
Ghostbuster(offset=3, strength=20)
ConvertToYV16(matrix="Rec601", interlaced=false)
aWarpSharp(depth=16.0, blurlevel=2, thresh=0.5, cm=2)
I don't know if thats a little bit more what you are looking for? Might need some correction.



I did also open in Virtualdub and using:

De-Sharpen Amount: 128 Radius:3
Spotremoval (deactivate all and choose VHS, it makes it a bit smoother)
GhostRemoval O:5 I:14%

Sadly GMJCZP died way back on Dec 11 2011, he was a much loved contributer to this forum and we all miss him,
the world missed him so much that they erected a statue of him back in his home country of Japan.
This world will never again be the same and I know that if he were still alive, that he would not want us to grieve for him,
he would want us to celebrate his life well spent, his most rare gift of making everyone that met him feel a part of his family,
let us remember him with all of his faults and all of his gifts, a real human being, a son, a brother a, a saint and a sinner,
he had his faults but was oh so very near to being a saint, we miss him so dearly.

GMJCZP, RIP. We Miss you.

EDIT: I have heard that GMJCZP might be brought back from the dead, all you have to do is say (out aloud),
"I do believe in fairies, I do believe in fairies", maybe it work, maybe it dont, who knows, maybe you just
get stuck with a bunch of fairies instead.
