Need advice: bad DVD artefacts suppressing

[wOxxOm]

I have an original DVDs collection of Avatar the last Airbender, and while majority of content is coded correctly there are about 10 out of 40 movies that originally were written the wrong way.

EdgeFine.jpg attachment show how edges look in majority of cases (fine), check the hat.
EdgeBad.jpg shows some meager mind at work of coding the content :-(
EdgeBad2.jpg shows another kind of artefact - a "dashed" edge
EdgeBad3.jpg - .... no words can describe it!!! (try to scale it to full screen size)

These stills are taken prior to deinterlacing, they represent the original DVD picture. Bad ones are the same being viewed in VirtualDubMod, MeGUI AviSynth creator, nVidia pureVideo player, MPC+FFDShow. And what's sadistic - there are short bad sections inside good ones... Of course every imperfection being magnified to a 1600x1200 22" monitor just gets sooo worse.

Currently I'm using MeGUI x264 codec to compile an ideal backup (10 DVDs to 1), so since 75% of contents is just perfect I decided to try to improve other clips as much as possible.

I wonder what can I do to conceal such artefacts...

Looks like it could be dot crawl. You tried Tcomb yet? It goes before IVTC I believe in avisynth.

thanx, but no changes seen since the halos are embedded into factory shipped progressive section of the clip.

nice, thanx, now it'll be my primary helper since before I had to visually check ivtc'd avs output for stray combs and mouth hashes. Hopefully I'll be able to dehalo as well.
p.s. funny, the only guy to hint me the solution lives in the same city with me

Hi wOxxOm,

This is one of my favorite shows.

I, too, have been working on getting these cleaned up and have started two threads about it in the past. Perhaps they will be useful to you:

amazing! thank you, your script with dehalo_alpha is 99% perfect, just pure magic, I never thought it's really possible to fix :)

and for those VFR (as in the first thread)... use YATTA ;) ...
