This link may help you decide where to buy. If I’m not mistaken, I believe Steven was the one who first posted it on the forum.

Willie: it turns out my platinum moment should have been “bias” instead of “offset,” i.e. I should have been working with “DC-bias” and not “DC-offset.”

Setting the DC Bias Adjust to 0% in Effects>Amplitude>Normalize did the trick! It lined up the centerline of the waveform on the zero voltage line. Doesn’t make this piece sound any better, but it might help on another piece if its offset – er … bias – were more severe.

It sounds good, so I’ll just leave it alone. Perhaps my misconception that this is the result of a DC offset is one of MY platinum moments!! Thanks for your always prompt replies.

What !!! … Willie dense ?? Nev-va …!! I’m the one who’s not clear and I apologise for that.

I recorded a musical piece via the line-in port of the sound card, and when I loaded the file in the Edit View in Audition, the lines of symmetry of the waveforms in both channels are below that red line running across the pane to the infinity symbol on the righthand scale. The centerline of the waveform is at -18% on the righhand scale. I seem to recall reading that this may be caused by a DC offset but maybe I’m all wet on that.

Perhaps I should’ve asked instead if this condition is significant, and if yes, how to correct it.

Not sure I understand what you want done but to re-sync your audio and video, you need only Shift + click on each track, right click either track and “Link Audio and Video,” and you’ll see a small box telling you how much, if any, they’re out of sync. Then just right click on either of the boxes and you’ll see a command to “Move into sync.”

Make sure you have room for the clips to move to bring them into sync. If this isn’t what you want, please post again.

Mystery solved! – it’s the mic!

I’ve been tied up for a while and just now got around to running some more tests. In addition to the OFF setting, the mic I am using has a ZOOM and a GUN setting, and in the GUN setting, it records in MONO! Nothing in the mic’s poop sheet says anything about this, good grief! Or … is this common knowledge and I’m just not with it?

The other tests show the PC-100 recording in stereo with the mic’s ZOOM setting (mic zooms in/out in step with lens zooming, although there’s a slight pitch change at the tele-end), and, of course, with the mic turned off or removed.

Thanks again to you all for your interest and help. Couldn’t have fingered the culprit without your input.

If mending mini-DV tape is like mending audio cassette tapes, then a procedure I’ve used many times successfully is to overlap the ends to be joined, cut together at a 45

Thank you all for your responses. Just ran some tests with these results.

>Are you using a external mike?
Oddity occurs with clips shot with and without external mike. In the most recent case, the entire session was shot using an external mike yet captured mono segments occured either in consecutives captures or sprinkled among stereo captures.

>Have you tried capture using Scenalyzer Live?
No … don’t have but it’s worth getting if not for the other features you mentioned; thanks for advice re V2.

>There is a big difference between audio only on one track of a stereo pair and mono.
I placed a stereo clip on the Timeline in PPro 1.5 and audio shows up in a stereo track with both L & R channel waveforms. A repeat with a mono clip has audio showing up in a mono track with a single waveform.

Does this suggest that the PC100 is in fact the culprit? I’ll try capturing the ame tape using another DV-cam, as well as shooting DV with another cam to rule out this camera as the culprit.

Of course, I welcome any further suggestions offered.

Cheers

Thanks for your response, David. You’re correct that the PC-100 doesn’t have a mono setting; only 32 kHz/12 bit or 48 kHz/16 bit stereo are choices.

I’ve tried different firewire cables with same result. I’ve also plugged it into two different firewire ports but both ports run off the Audigy2 card, so perhaps the card is the culprit? (I’m running latest driver, too.) It might be the PC100 but I’m inclined to think not because prior to capturing with Premiere, it worked with Sony’s DVgate with nare a problem. Of course, the PC100 might have developed a problem coincidental with the switch over (don’t have DVgate installed anymore for a test.) I’ll try a test with anoter DV-cam, however.

Thanks again for the heads-up on where to be looking for solutions.

Cheers
