It looks like a film scratch.

There is a Descratch Avisynth filter, for cheap/free methods: http://avisynth.org.ru/descratch/descratch.html

Sample script:

Code:

AviSource("input.avi")

LoadPlugin("descratch.dll")

ConvertToYV12()

DeScratch(mindif=2)

Are you familiar with using Avisynth?

And then there's also some high-end software like Davinci Revival: http://www.blackmagic-design.com/pro...avincirevival/
Or Diamant: http://www.hs-art.com/html/products/diamant.html

Remember to attach images, files, etc, to the forum: http://www.digitalfaq.com/forum/show...ages-1529.html
We try to avoid external sites for linking to images/etc. (As explained in instructions.)

I think you're making the script too complicated.
Is that something you wrote, or something you found on another site and did a copy/paste?

I would start with the default, as per the filter's manual:

Code:

AviSource("input.avi")

LoadPlugin("descratch.dll")

ConvertToYV12()

DeScratch(mindif=2)

Notes:

Now, obviously you'll have to change AviSource to whatever your actual input method is. Do NOT use DirectShow input.
LoadPlugin is best with the full qualified file location. (C:\Program Files\Avisynth\plugins\etc etc etc -- whatever it is.)
ConvertToYV12 only if needed. (Again, depends on source.)
Use the basic DeScratch, see what it does at a default setting.
