Question about Analogue Tape Tracking Errors

[krieger2005]

Hi,

i guess that "Analogue Tape Tracking Errors" are these errors, which cause "wibbling" frames when capture a video from an analogue video tape. Am i right?

If so, what filters out there, which can handle this? I guess not much (if any).
Maybe someone know a good site which describe this effect and maybe also give a hint for a solution (not that type of solution to setup better you video player.. just one which can be realized in a filter). I just ask because google give thousounds of answers and maybe someone have just a hint.

Thanks

Its called timebase error due to the tape streching and other machanical weakness of VCRs. A black box "TBC" or a good VCR Ex. JVC 9900 $499.95 new. US. Go-Ebay

No filter to help here.

But if this effect is recored so on the tape self? I thought on something like "time-based edge-stabilisation-Method". But it seems that there is nothing about that.
Can someone tell me, if this shifts in the Picture, which cause the "wibbling"-Effect is an absolute shift in the picture (vertically) or a dynamic shift (for example: Till a position a shift by 5 Pixels, then 3 and so on)

The error may be equal split between the machine that it was recorded on and the palyback vcr, or the precentage can vary. This playback machine in most cases is not the one that you recorded with. If it was a prerecorded commercal tape, then you will benefit by a TBC box or a good VCR like the JVC 9900.

Why there is no plug-in that can help is because there is no vertical or horizontal sync pulses recoreded on your captured clip, so there is nothing to compare.

though clouded has demonstrated an ingenious way doing a partial TBC. so long as the source isn't too bad it's quite usable (and there's not too much black in the picture). it's a step in the right direction, though i seriously doubt a perfect TBC can be achieved any time soon.

Where do seen this demostration?
