Hello,

I have an old episode of NOVA that I ripped from a vhs tape (no longer have the vhs tape). I'm testing out virtualdub and some filters to clean up the video. The video isn't that rough (for its age) but there is just this fine "line of fuzz" on the bottom of the picture that I can't manage to filter out. I tried to use manual tracking with the vhs tape but it still wouldn't go away. Is it even possible with virtualdub to filter that out? or should I use avisynth?

I have included a screencap so you can see what I'm dealing with.

I've seen worse and it's normal to have that "line of fuzz" at the bottom . The only option is to crop and add black borders.You crop about 8 lines and you add borders 4 top - 4 bottom.
If you want more help to clean the whole frames post a video sample. I can see chroma noise green/pink horizontal lines
good luck

Take a look at this post: http://www.digitalfaq.com/forum/vide...converted.html

While there are some methods to truly remove that noise, instead of just mask it, there are side effects that can lower the quality of the interior image.
So it's still best to mask.

It's better to add 8 to the top or bottom instead of 4/4 to optimize for compression - for example MPEG2 macroblocks consist of 8x8 pixels and you should align sharp edges to block boundaries.

For both clips you can try this script which gives you this
After that or perhaps before you may want to deshake this video a little (vdub's deshacker comes to mind)..i haven't bothered
