Lines on the edges of suits

So I thought it was a halo or ringing - DeHalo_alpha and HQDering doesn't do anything. Nor does antialiasing filter. Given it's on the edges - I'm thinking the solution has to be mask-related.

It's an anime, shouldn't there be lines at the edges of suits and basically anything?
You might want to share a screenshot in which you mark what is bothering you.

It's not an anime - hopefully the red circles help with identifying the weird edges

Sharpening halos along transients.
You may use convolution to compensate that.

Hmm defining the matrix is more fiddly than (most) other Avisynth filters - this will be fun!

I just made such a pair of compensation kernels for positive/negative gradients with more than -+10 taps horizontally.
Worked nicely here for the huge ghosting halos of an aged CCD Handycam.

But indeed it takes lots of time to handmatch so many taps.
In your case I guess -+1 to -+4 taps might do.

Hmm, now that I have downloaded and examined your source video:
Only the cuts of the arrival scene cam have it, the artifacts don't follow the contours perfectly,
rather form exact vertical colums, as seen with an uprezzed shot from a poor cam.

Another cam fault: echo trails of lefthand bright parts (outside handrail run and floor) propagating to the right,
visible as pale overlay over dark content decaying by (1-1/e) after 10 to 90% of frame width (lady's black gown, men's dark suits).

Often seen fault, let's make a script to compensate that !
Or is there a plugin already ?

The other cam's close-to-face cuts do not exhibit the first fault in that depth,
but the second (rightbound bright trails), although to a lesser degree (white handkerchief)

Maybe a different approach is needed here.

@Emulgator, to be honest I do not understand what you are talking about. Is there a tool, sth to try out ? Huge ghosting halos is sth I am also really interested in any best practise.

@Emulgator, I wasn't able to use the script above. But I did find a simpler script in your other posts.

string1 = string(" 0 -20 28 -32 36 36 128 128 72 -56 12 12 -4 ")
mt_convolution(horizontal=" "+string(string1)+" ", vertical=" 1 ", u=3, v=3)

So the left-sided halos are removed really well - just the right-sided ones and it doesn't seem like the overall picture has been softened/blurred.
