VHS-C Video YUV data capture through DV Converter DAC2, but problems!
Frage von Onkel Benz: September 2005
As already described in the title, I try to capture old VHS-C material. And this with help of "YUV DV Converter Datavideo DAC-2", but there is always to frame loss. Per half hour, I raise my loud (premiere 1.5), 73 frames were skipped. At DAC I have the original camera, with which the material was recorded, had previously tried on VHS recorders and cassette adapter, but the same problem. Why is that? What can I do?
Hmmmm ... just tried, but everywhere the same problem. If I close the camera so s.den Television s.treten no jumps. Hab grad found that it is not just a frame, which is omitted, but half a second, or 12 frames per error. No idea how I should get the material now in the computer.

The video signal appears to be so bad that the converter will lose synchronization. When TV is known to be less fastidious with respect to the video signal.
So is it the video signal back on its feet put to the video signal enhancer neudeutsch ". There are different procedures. Too weak or broken sync one should discard the original synchronization signal, and instead a new dazubasteln. It can not all enhancers, some treat only the brightness, or color, or fumble around s.der sharpness.
But after some people have used sync-enabled Videoenhancer to enhancer copy-protected video signals ", these new boxes alone and now difficult to obtain. If then "Macrovision-killer" draufsteht, is the distribution offense.
There are as synonymous converter models of Canopus, to bring a signal conditioning. Roughly speaking, everything may have a TBC (Time Base Corrector has installed) synonymous restore the sync signals and more.
Overall, it all sounds like a fat wallet, and after much effort. Maybe come to target faster if you ask a video dealer or local video club rental units for advice and, if necessary.
Good luck The fat Stefan

I had a problem once synonymous with dropped frames during digitizing analog video recordings. There were always pictures of lost when turned up between shots unrecorded space agencies. In this case, the temporal offset between the picture took out (and again dropped frames) and sound (always present in its entirety) for more.
Sometimes the only TBC, as of Stefan recommended. You can get it either as a separate device (1) or in the delivery of an A / D converter (2) contain ...
Used 1): Electronic Design TBC-Enhancer, or TB Light 2) eg

I've nem friend of the Pinnacle MovieBox DV loan and the time connected and lo and behold, with the everything went perfectly. VHS-C material is of such poor quality anyway, there was no loss of quality here anyway to be expected. But Mark, you're right. The forfeited gone then occurred when frames were just blank areas on the tape. But not only synonymous so were the same mistakes again s.den places synonymous s.bespieltem material. I have several times in front and back wound, the errors were always s.den exact same place. With a lot cheaper MovieBoxDV no errors occurred.
