good soft for capturing "VERY" bad VHS tapes

[reb0rn]

I did many test in past and not even one capture program/codec could not have good audio/video sync whan i have bad part (empty or totaly bad) in vhs tapes...
But it wos like 1 year so i hope there are updated appz out there.. virtualDub 1.5 and VirtualVCR than wos very bad for sync

Whan i want to do mpeg2 capture best appz for good (sync is OK for 1h than get worst ..) capture wos Intervideo WINDVR but at mine home PC it has overlay problems with Nvidia vivo drivers.. i can not see preview while recording.. and it lose audio if there is very big trash on vhs tape...

So i need good appz for lossles M-jpeg capture if i want to do almost perfect picture I did some test with new Vdub looks OK but i have no bad tapes at home so not shoure...

And also i need good mpeg2 capture program some that is better than WinDVD with audio/video sync...

PS: I am using Nvidia 6600 Vivo for capturing

I am just going to pass along what has worked for me. I have five workstation with the same setup.

1. I use all ATI-AIWs of verious models. I never have any audio sync with the following setups

The spec are these, PAL 756x480 25fps 15,000 cbr de-interlaced.

1. ATI's native Mpeg2 capture program. Perfect

2. ATI-AIW VirtualVCR with Panasonic DV or Leadtool's MJPEG Perfect

3. Same as above by using IO/AVI capture program. Perfect

All NLE capture for Mpeg2 using DirectShow have been disapointing.

What hasn't worked is any Virtualdub(xxx) version, too many dropped frames. Hats off to Virtualdub and its spin off for everything else it does great.

I not saying VirtualdubVCR doesn't work, I just haven't tried it.

Hi,

I use VirtualVCR with good results. No A/V sync problems. Few dropped frames. Very configurable (framerate, size, colorspace, ...) and free. I cap VHS PAL footage at 768x576 with a Hauppauge wintv go (bt878) and btwincap drivers. Usually I capture uncompressed video but for transient captures (record, see, delete) i cap with MJPEG PICvideo codecs.

With this specs I capture almost all the information the VHS player sends. But for bad tapes this isn´t enough. Dropped frames and bad quality image is the habitual result.

Then postprocessing (hard work with avisynth filters and trial an error) is a must.

IMHO, for bad VHS tapes not only the capture hard/soft is important. Buy a VCR player with TBC, an external TBC or both. And learn avisynth and all the powerful denoise filter actually available.

Good luck

whats TBC? mine player is some cheap crap its not so old but... ;)
i did some test with Vdub + Picvideo and quality is gr8 A/V synk OK but duno for long capture becouse this tape wos just 12min ... no droped frames but Vdub inserted some 50 fremes for 12min capture prolly to keep sync with audio which is default selection for capturing...
I had few problems nor Mainconcept not CCE could not do direct reencode from that AVI like it wos some uncompatibility with picvideo codec..
Than i used Tmpgencoder which did it fine ...
I am not yet well used with AVIsynth duno can it do mpeg encode?.. I know it has lots of filter for cleaning/cuting i tested some but atm i do not need it... I am doing very cheap VHS->DVD that can only cover mine electric power and blank DVD so :P

@rfmmars yeah some friend also told me he has no sync problem with his ATi card with HW mpeg2 but its not option now.. maybe in future

Hi,

TBC stands for Time Base Corrector. It's an electronic device (a PCI card or integrated in good VHS players). His scope is regenerate synchronization signals at video reproduction. It can regenerate frame synch signals, line synch signals or both. Image/sound signals aren't changed. Then dropped frames dues to lost of signal are avoided. Distorted lines dues to mechanical tolerances in the reading process are avoided too.

VirtualVCR uses another approach to resync audio/video. Instead of inserting duped frames it modifies sound's pitch.

I have usually no synchronization problems. If any, I have demuxed the audio and processed it separately.

Good luck
