Halo/ghosting?

[color]

Halo problem

I am trying to "restore" this as good as possible. But there is a halo on the right-side (or ghosting, i did try ghostbuster and dehalo but i cant get it good at all), is it called something else and what can I do to fix this? There is a bit on the left side but not everywhere.

There is to the left original and to the right the one I am working with in the file on wetransfer.

I have also tried VHSHaloremover() it sort of works but it makes the overall image really blurry.

Try
dehalo_blah(rx=1.6,ry=1.6,darkstr=0.45,sharpness=100,sharptype="slow")

Give Dering a try: https://forum.doom9.org/showthread.php?t=184570

FFImageSource("Screenshot-20221226-081020-2.png")
Crop(0,1,0,0)
ConvertToYV12()
Dering(last)

The result is by no means perfect but maybe it can be improved by tweaking the parameters. I remember you saying you only use 32-bit AVS+, well this plugin only works with 64-bit AVS+ at the moment. Although, support has been added but no current test version.

You should try your own suggestions :rolleyes:. That does not do anything against the haloes, it just sharpens the image a bit.

I have accouly started using 64-bit as well. i have installed for 64-bit now so its possible for me to use it now.

I will check it out and dehalo_blah

Ok, you can change other value and remove shape if you don't like it.
Example
dehalo_blah(rx=1.6,ry=1.6,darkstr=0.45)

I did try, I think Dering is the best, but I think it needs a bit more tweaks.

clip1=VHSHaloremover()
clip2=dehalo_blah(rx=1.6,ry=1.6,darkstr=0.45)
clip3=Dering(last, A=0.3, W=4.5, RelVisibleTh=0.001, AbsVisibleTh=0.005,PostFilter="median2")

BTW, I can not crop 1 pixel .Crop(0,1,0,0) I get "Crop: YUV image can only be cropped by Mod 2 (top)" I did try most but I get "Image height must be multiple of 2", I tried convertto and tried colorspace here: http://avisynth.nl/index.php/Crop

I only cropped because the image you supplied in the first post had an odd dimension. If your video is already YV12, you shouldn't need to crop.

Try Crop(0,2,0,0) or you need change to other colors space :D

like i said when try other value:
dehalo_blah(rx=5,ry=1, highsens=10, sw=5)

more shapen:
dehalo_blah(rx=5,ry=1, highsens=10, sw=5)
ex_unsharp(0.2,0.4,float(width())/5, 1)

My attempt:
a=last

msk=ex_edge(mode="kroon", lo=150, invert=false)
msk=msk.ex_expand(5,mode="horizontal").ex_blur(2,0,mode="gaussian")
ex_unsharp(-0.5,0, Fc=704/4, th=0, safe=false)
ex_merge(a,last,msk,luma=true)

MCaWarpSharp4(4,4)
interleave(a,last)

I think this looks so much better. Thank you. ☺️
