I am trying to encode a video, but as you can see below the video is fairly degraded.

user posted image

I allready know how to filter out some of the noise, but does anyone know how I can fix the stabillization problem that is causing enitre rows of pixels to be moved to the right? I don't care if this ends op putting a bunch of black pixels on the right side, since I can just crop them out.

Well, it seeems you need to crop and resize the image.I guess it is the only solution.
Also, try to use another VCR.

Well first of all the problem is more than just the black line, it is moving entire pixel rows so even if I crop it out it still won't help. Second, I don't think the problem is the vcr but rather my video capture device since the problem doesn't show up when I play the tape on tv. Since I don't have access to any other video capture devices there's really nothing I can do. Wouldn't it be fairly easy to program a filter that would shift rows of pixels to the left for evey black (or close to being black) pixel at the beggining of the line? I don't know how to do that myself, but if anyone here knows how to program filters...

*sigh* well I see no one is intersested in helping... Could someone at least point me in the dirsction of a place I can learn to program virtual dub filters myself? I know a bit of asm so I should be able to do it.

While you're at it, could you make me a simple transition filter? : )

It would be nice if they had an SDK that you could drag a filter from another program into and convert it to a VDub filter. Then we wouldn't have to be a computer genius to make one.

You can download the Filter SDK fonr virtualdub's site, and it comes with an example filter programmed step by step and commented. It's really well explained.

And you don't really NEED asm, although using it wisely will increase speed :)

EDIT: rethough something :)

Anyway it'll be damn hard to do this correctly. How you know if you're trying to move a distorted line or line with some blackness? And how you know how much to move it?

Are you having this problem only with this Video or all the captured videos have such jagged lines
