Here’s a baffler…

Michael,

Its drop frame, but as Walter says, that really shouldn’t be an issue. In fact, the fact that it had timecode at all should have made it syncronous throughout, but…

The big issue now is time and more of the same interviews after this one. I think this will wind up being charity work at a time when I need the money. Ugh!!!

David,

Check your individual clips if they were indeed 48.000 KHz,
or were they maybe 48.012 or some wierd number like that.

Happened to me once long time ago, don’t remeber what caused it,
chenged those figures back to 48.000 KHz and no problems.

It was only handfull of clips affected, so you might ne lucky
as well, if this happens to be your problem eventually.

I think that I attributed this problem to my Canon / Firewire / Hrad Drive issue,
not sure.

Does this drifting audio stay in synch with the picture of that camera? Also, the audio rate really is 48k, not 47,999 or 48,001 3/4?

[David Roth Weiss] “is that its possible that there was some audio clipping on one camera and that might have caused an intermittent voltage issue inside the camera”

I’ve seen photographic strobes cause audio to drop out or clip. I’ve seen clipping audio cause artifacts in the picture. If the audio was really clipping outrageously hard, well, who knows?

I’m unclear about something. One of the camera’s audio starts drifting? What about the picture? Does the video for both cameras stay in sync?

One thing I’d try right away, if you haven’t already, is playing them back on a completely different system. Maybe even a PC. Take the Apple DV decoder out of the picture completely just to test it.

I’ve had that issue as well, but not this time. That was the first thing I checked.

Yeppers!!!

First thing I checked… its all 48.00khz[Arniepix] “I’ve seen clipping audio cause artifacts in the picture. If the audio was really clipping outrageously hard, well, who knows?”

Yep, and I’ve seen entire digital files get corrupted by clipping, so…

Yep!!!

Unfortunately Sean though I have PCs here, I no longer have editing software, so I have no way put two tracks up against each other.

THNX for the idea though… Its would be interesting to test.

Just (approx.) sync the two tapes to the same point on two players/cameras and PLAY them at the same time and see if they drift… without capturing.

That will answer a lot of questions.

Thanks Matt, but I don’t have two DV decks…

That’s why I said “two players/camera.”

Don’t you have a camcorder?
