Removing bad static and head switching noise?

[turnipzoink]

Hi there
I'm trying to filter this video. Two things, the v-sync at the bottom, and also the static bar. Is there anything I can do about that. I'm using MeGui and will convert to mpeg2 to H264. Please see attached.
What filters should I use?

Thanks

The damage is way too bad to even think about filtering it out. You could crop it. :)

re-capture with a different VCR. If that's actually what's on the tape (on every VCR) then there's no hope.

btw, the MPEG-2 has visible encoding artefacts (blockiness) - you might want to look at your whole workflow. Try reading some threads in the capturing sub-forum, or the relevant forums at videohelp.com

Cheers,
David.

The original VCRs are unavailable so I'm stuck with this.
I had some improvement filtering the static with another filter (can't remember which one). I just thought there might be a filter specifically for this, or something that can blur it slightly and make it less distracting.
Thanks for you replies.

using some extremely aggressive filters the static could probably be mostly removed, but there wouldn't really be anything left of the picture either.

Fear not.

Based on the frame you have provided, the static is primarily in the odd field. The two attached images show the effect of discarding one or the other fields - i.e., the most rudimentary form of deinterlacing. It may not be perfect but at least you can see the guy's head!

Chances are the static will be in the same field for most of the video (due to one of the two heads being buggered up)

I suspect after dumping one of the fields, the remaining field could be cleaned up further.

EDIT - the remnants in the even field may be due to the MPEG and JPEG compression applied post-capture.

what you should probably do is create a mask so that you can apply all of the over aggressive denoising to the sectioj of video that actually needs it, while protecting everything else. If the intereference band is spatialy stationary, this should be very easy.

Hi
Great, that looks much better.
How can I create that mask using MeGui and Avisynth?
(i'd like to keep to the same software to avoid the learning curve if possible. I think I mentioned in the thread title I am newbie (it got renamed) so please can you explain explicitely, but I am following so far.)

A question. Would not having to code so much noise in that bar save the bitrate that can be used for the rest of the picture?

Also, is there a way of blacking out that nonsense at the bottom. I tried cropping out of the bottom 10 pixels or so, but the program complained that I might be messing up the compression scheme if I don't use a standard size

I'll have to defer to someone else to answer about MeGui and Avisynth, it what you need to do is apply a deinterlacing filter that simply throws away one field (don't use a fancy deinterlacing method). It certainly is a good idea to mask the bottom to remove the switching noise. As far as bitrate goes, the source is so low resolution anyway, I can't imagine you'd need a particularly high bit rate.
