Line/"Dirt" removal/reduction

[Abyssal]

So when messing with AviSynth for an anime movie from 1988 I noticed this line, or some kind of dirt to the left in the picture that moves a bit while the image is shaking.

As you can see to the left, there is this somewhat thick semi-transparent line that fluctuate as the video goes one.

The movie is from 1988 as mentioned above and it got a HD remaster.


Here is a video sample:

So what I want to know, is there any name for it? other than... "dirt"?

...and what are my options for tackling this? (i.e. removing it). I have looked around a bit and noticed all the restoration scripts etc. but I feel they are way too massive and complicated since my only goal is to remove that line. :rolleyes:

have you tried something like RemoveNoiseMC? it specializes in spot removal.

or you could always try saving the affected frames as .bmp files, changing them in photoshop and then placing them back into the video.
