[INFO] DeRing vs DeHalo?

[Selur]

trying custom code:

import color
clip_limited = core.std.Levels(clip, min_in=16, max_in=255, min_out=16, max_out=235, planes=[0])
diff = core.std.MakeDiff(clip,clip_limited)
mask = core.std.ShufflePlanes(diff, planes=0, colorfamily=vs.GRAY)
mask = core.std.BinarizeMask(mask,120)
mask = core.std.InvertMask(mask)
for i in range(25):
  mask = core.std.Inflate(mask)
filter = core.std.Expr([clip], expr=["x 40 -", "x", "x"])
clip = core.std.MaskedMerge(clip, filter, mask)

Extended mask adjustment might help, but it's probably a lot of try&error.
