Recording consoles w/ video cap device: audio sync probs

[louisg]

Hey, I sprang for an ADVC-110 video capture device, and I'm getting audio drift issues. I had to unlock the audio because I guess game consoles don't have a very tight clock for their NTSC output. After a few minutes, the audio gets out of sync. I've heard one solution is to run the console through a VCR that has a TBC, but what are some other solutions? Does anyone know if it'd work to record the audio separately and match it up later, or is this kind of sync issue caused by the video not being quite the right speed or dropping frames? Anyone have experience with this stuff?

I would try a different recording software first. The ADVC is a live DV encoder. Try iuVCR or iuVCS. These are known to keep the sync, even with weird source signals. If the issue persists while running audio through the ADVC as well, feed the audio directly into the PC (sound card or onboard audio device). iuVCR can mix different sources and will keep the sync on it's own.

Hmm I didn't realize software had much of an impact on something like this. I'll give that a shot, thanks. Any recommendations for software on a Mac?

If you're on at least Mountain Lion (10. you can try http://krylon.rsdio.com/zakk/cocoasplit/

Although it's focused more on streaming, so if you're trying to capture uncompressed or lossless that's not going to work. H264 only.
