Colour flicker across top of capture

[n8n]

Hi.
i've been having a seemingly random colour flicker across the top 1/5 of anything that I attempt to capture.
i'm using a Leadtek winTV200 Expert cap card. I've used both the video composite and video tuner input lines with no change. I am capturing VHS video and i'm trying to determine what the source of the flicker is or if there's a way to filter this out with avisynth. If I am viewing the vcr output through Virtual VCR, then I will see the flicker at the same time in the tape, so maybe it's not that random. However if this is recorded on the tape, I do not see the effect when playing back on a regular TV.

*correction* I just played back this particular segment using winpvr and VVcr and neither showed the flicker this time. I have though had episodes where the flicker was repeatable, so I think that rule out the original recording....

i've attached 2 .jpg's that are 1 frame apart, one's good, the other's bad.
Oh. i'm also using huffyuv 2.1.1. with cce patch v0.2.2 : I think that's the latest.
If anyone has any suggestions or has seen this before, i'd appreciate your input

the problem lies in the standard you're watching: NTSC - Never Twice the Same Colour.

you can probably filter this out using avisynth post-capture, and i'm sure there's hardware around that specialises in this kind of stuff (most likely very expensive and of limited use unless all you ever do is VHS caps and you get paid for it).

the problem is there on your tape unfortunately.

if you can send a sample (high-rate interlaced xvid is fine for this purpose) i could see what i can do with it, but i don't want to get your hopes up - something like this could be very hard to remove without pwning the good parts of the video.

[edit]

oh, it changes after playing back a second time? it may be tracking then. try averaging multiple caps if you have the time and disk space. there's loads of info on doing that on this forum.

Thanks.
I did some more digging, now that I have a good direction to head in and also discovered a filter called cnr2(). i think that the averaging could work out better, although more time-intensive, in the end.
