VHS rip audio is not snyced - can i fix this?

[Nvidiaguy07]

So I just started the process of putting old family VHS movies on my computer and then eventually on DVD. I did a few which at first glance seemed ok, but then i noticed that the audio doesnt sync as the video goes on. At about 10 mins its almost a 1 second difference between lips moving and sound coming out.

Is there a program that helps you fix this?

Im currently using Cyberlink PowerDirector to capture the videos as AVI files. should i be using something else?

Also im sure my capture card has alot to do with it, its a older K-world piece of garbage (wont even work in vista/7, makes me lock up), so am i better off just investing in a better one? my only worry is that im gonna have the same problem with a new card.

Not to mention every card out there has mixed reviews, all i want is a card that will let me hook my VHS up to my pv via RCA cables and rip these videos.

Let me know what you guys think.

This unfortunately tends to happen with a lot of video capture hardware - if you lose any frames due to signal dropout from the VHS they get lost, but sound is recorded at the same rate regardless, and sync goes out a little at a time.

It's not easy to deal with unfortunately. Back when I used to do this stuff I bought a quality box to do it with, after trying various cheaper TV cards and video capture cards. What hardware are you using to capture video?

The best equipment I've used for this was a DV bridge ( http://www.grassvalley.com/products/advc110 ), a box that takes analog video and sound in and spits out firewire digital video, and capturing that on PC. It was not cheap Some camcorders will apparently do a similar job if you have one, but not all will perform this conversion on an incoming video signal from another VCR.

If you're stuck with your hardware your only real option is probably to capture the video in smaller chunks, instead of the whole tape in one go, and then join them up afterwards. There isn't really a software way to do it, because the times when you lose picture/sound sync are sudden jumps rather than a consistant difference in sample rates.

The ADVC110 is your best bet for affordable audio/video sync.

damn theres no other way to do this?

im thinking there has to be a program out there that can at leats match up the audio and speed it up by .0001x to make it sync

im thinking if the video looks like this:
video ------------------------------- 10mins 31sec
audio -------------------------------- 10mins 32sec

why cant you just sync up the end of the video and then have it balance out?

so for example if video one was playing at 1xspeed the only thing you would have to do to make the audio sync is make it play at .999x speed and they would end up balancing out.

I know this might sound crazy but i feel like someone could create a program like this, so hopefully there will be one out there? lol

Give virtualdub a try first: http://virtualdub.sourceforge.net/

If it is a constant rate, then you can stretch the audio by a percentage using virtual dub. Honestly, it's probably a lot easier to do this using a DVD Recorder unless you want to do manual editing of the files on the computer before outputting them to DVD.
