DV input sync problem

[Jeremy Case]

Hi all,

I'm having a problem with Firewire-inputted DV that the audio coming off of the Firewire input is slightly behind the video (maybe 4-6 frames if I was to guess, though I haven't measured it yet). I hooked up auxilary analog audio & video outputs from my DV deck and put then into Preview alongside the Firewire input, and here's what I found: video from both the analog and Firewire signals appears to be in sync, and the analog audio appears to keep sync with both video signals. So in the meantime as a work-around, I'm recording Firewire for video and analog for audio, and it seems to work fine. Has anyone heard of this problem, and is there some way to correct for this (similar to the sync settings for VT [1])? Or could this be hardware-related (I'm coming from a JVC BR-DV600U deck through a Belkin 3-input PCI Firewire card)?

Thanks,
Jeremy

Does it seem to be off only during digitizing, or is it out of sync when played afterward from the HD, too?

[Jeremy Case]

The delay is present in both the live and hard-drive recorded signals.

This is quite peculiar, and I've not seen anything like it. Are you running VT[3]?

[Jeremy Case]

No. But I'm running the latest build of VT 2. I looked on the discussion boards at Safe Harbor, and found a few mentions of people having the same problem. The only mentioned work-around I heard was what I tried: namely, Firewire for video in, and analog for audio.

Thanks,
Jeremy
