Looking for filter to remove crawling lines / noise from VHS caps

[STC-Fan]

So far I've tried several filters to reduce this noise I've seen on several PAL VHS tapes I've capped recently - I found the best one so far was the DotCrawl Comb Filter. Using the "Trellis Correlation" and the "4-way 5-tap with saturation" settings, I've been able to reduce quite a lot of it, but some of it is still noticeable - I've uploaded two short HuffYUV clips from one of the tapes here, (http://www6.rapidupload.com/d.php?file=dl&filepath=12999) one which hasn't had any filters applied to it, the other which has had the DotCrawl Filter applied with the aforementioned settings.

I tried using the more intensive "Multi-path delta" (or whatever it's called) spatial filter, but it didn't make much difference. So, I was wondering if any other filter existed out there which could better remove this kind of noise, and possibly do it a bit faster as well =P

P.S. I did also try that DFN VHS filter the other day when I saw it on these forums, but found it wasn't as good as the DotCrawl filter.

P.P.S I posted a similar request on the Unofficial VDub forums not long ago. However, I got no response, so I'm trying on here, as it looks to be a bit more active =P

Instead of trying to remove crawl, I suggest getting a VHS player with S-Video out and capturing from that. Always fix the problem at the root if possible.

Thanks for the suggestion - I've actually viewed output from VCR that way before, why I stopped doing that is a mystery to me - probably because my SCART to S-video adapter broke a while ago, and your post made me think "well, would it really take that long to fix the sunken S-video luminance pin?" (just now, it took all of, erm, 1 minute =P). As it's late now I'll leave a direct comparison till tomorrow, but it looks like the rainbow lines have virtually gone.

Update: OK, I did a comparison of the old capture with the new one (a sample of which can be found here (http://stc.hacking-cult.org/other/new_svid_cap_sample.avi) - compressed in MJPEG @ 19, not altered in any way), and the image looks sharper and brighter (and less washed out), but there's still a load of the rainbow lines noise in the image. Still, it's better than it was before by some way :)

You can try this filter to remove crawling lines:

Thanks for the filter, but there's one small problem - the readme and the filter itself don't have any English explanation of how it works - I did try the filter out of course, but obviously without being able to understand what the slider controls did, it was difficult to get any good results =P

However, I've recently been able to borrow a "Miglia Director's Cut Take 2" FireWire-based unit, which produces even better results than the VIVO port on my graphics card. It's weird, really - when I was looking at the VIVO captures, I was thinking "yep, this is pretty bright, and isn't washed-out like the composite video output", but when I saw the results from this Miglia box, the colour balance was better still (notably, blacks are actually black, not dark grey =P), and none of those rainbow lines are present in the capture.

Hopefully I can borrow this long enough to recapture all my stuff :)
