Audio pitch problems capturing video from VHS
Hi
I started my project for this winter to digizite old vhs videos. I have these devices/tools: a) vcr sony slv se80 (6 heads) b)time base corrector (1t-tbc) c) avermedia ez-capture based on bt848 d) virtualdub I'm looking for the right setup, so I'm doings variuos tests. But I've realized that after various minutes audio pictch changes (it shifts to high frequences as donald duck voice). Any suggestion about settings? I've found articles about audio sync, but this problem seems related to something that affects pitch thanks in advance sareide |

Could you spend $50 to $65 to get a better card? Look at the ATI 600 USB card. - page1 from Amazon.com: http://www.amazon.com/gp/offer-listi...&condition=all - page2 from Amazon.com: http://www.amazon.com/gp/offer-listi...&condition=all Prices vary from seller to seller, month to month. Right now I see the cards from about $35 (cheap!) to $150 (crazy!) MSRP on these was in the $50-100 range, when new. Quote:
Sustained damage may be a forced change of kHz. If you alter 48kHz to 44.1kHz, for example, without doing compensation. (Or the other way around, 44.1 to 48 -- I forget off-hand. Would have to do a test in Sound Forge to remember which way causes chipmunk, and which one is slow-mo.) Where that is happening, however, I'm not sure. Quote:

hi
thanks for you suggestion. I have been using a dtv usb dongle with svhs, video composite and audio. But I tought that it would be better to use bt848 since the tweak with virtual dub. This dongle is based on the twinhan chipset . But I'm planning to buy a capture cart. Considering the pitch shift i have this result: the video is normal at its start but after some minutes voice alters becoming chipmunk. Pitch shift doesn't alter changing down just like a flip flop: it goes up and remains up, sustanined. Do you think that I have to change setup of virtualdub to compensate: but it's non a delay (out of sync). it's accelerated. I'll try to use usb dtv dongle. But could You suggest me any trick to solve this problem? thanks in advance sa |
VirtualDub shouldn't need to compensate.
And given that the skew is so bad as to cause chipmunk sound, I doubt it could compensate that much anyway. I've never seen an error like this. At least not one that I can recall in the past 10 years. I wish I had more advice for you. :( |
