Paused the video over the tracking issues. Ran the tape a lot of times over that area in slow mo. What did it do? Burned a hole in the video creating a massive drop out....

This would generally point to physical defects in the tape, where missing tape oxide has been further shed.
Quite often, dropouts are the result of flecks of tape missing.

Than thought about renting this machine for a week...

I did not know those could be rented. I must keep that in mind. :)

Admin,

Can you post a few pics of the Panasonic DMR-ES10 DVD in action a before and after shot of some video tearing.

If this really works it would be amazing.....

I can in a few weeks.
That particular piece of equipment is unavailable right now.

KP,

what does it actual do. If the video tears or looks like that spider man picture will it fix it. If it does, I will go purchase an ES-10 tonight. I have seen you speak many times about the ES-10, was kind of not clear what it actually does to a damage frame or picture that makes it worth using.

It has a frame sync that specifically fixes this error.
It intelligently rebuilds a new sync. (As opposed to the "dumb" sync you'd find in standalone TBCs.)

This seems to be pretty cool. May look in to this.

Hello,
I'm one of those technical people from Avisynth :) I can probably help. First of all, all these noises you talk about are in fact, extremely easy to fix. This might seem a revelation to you, but I have a tape now that won't play in 5 VCR's (only shows a blue screen), but one I did get to play, and was able to remove all white lines 100% and reduce noise dramatically.
Please capture your tape 3 times, with the settings below, then you can use a script to automatically remove the noise (kind of like a majority vote across captures).
Yes, capturiing reliably is an issue, until you know the secret settings.
VirtualDub
capture timing options
Only the following should be checked:
correct timing
auto disable sync
I have a diagnostic video and analysis system to verify that you can capture with no lost frames.

Note that the sample is a TRUE restoration, with no enhancement of any kind, I simply replaced the noise added by the tape. I didn't need any fancy equipment to do this, the software is all free, there are no adjustments to be made, and yes, you click the fix it button ;) (more or less...)

I know this is very old, but does anyone know what script can be used for this? Or would it be a custom script for every sample?
Thanks!

You know saw the reply to this in my email and thought someone had an answer.

I don't know of any scripts that can fix this, I use chroma keying, it takes hours to do sometimes have to re-draw the frames.

Tried everything from baking tapes to tape cleaning. Chroma keying the damaged frame area is the only thing that works most of the time. Not going to explain these methods it is to hard to write out.

My reply was about what I thought he meant by tracking error, however the sample he posted later was different from what I was thinking.

To answer your question, my post was talking about the median technique. There is now a great plugin for this, developed with my input.

As for Deter's actual problem, he never posted a sample so I couldn't develop a script to fix it.

JMAC, thank you for helping so many who struggle. In your original reply you had a link:

That link is broken - is the advise you are giving about avisynth a better path to go or just another thing to try? Thanks again. You are amazing.
