By the way this mini dv footage being captured as .mov files.
The behavior you describe simply doesn't happen under normal circumstances. The only scenario I can imagine that would cause this is recording the audio in 12 bit 4 channel mode, and using a different capture utility for the actual capture. That might create a file with two audio tracks.
Other than that, I just don't see how this behavior is possible.
Select all clips in Project Panel.
Right click and go to Modity/Audio Channels.
Disable the flatliner.
This must be done before setting the clips on the timeline.
How would I get premiere to caputre the audio in 12 bit?
By shooting it that way. However, PP will only capture the default 1&2 audio channels. You'd have to be using some other software to be capturing the secondary 3&4 channels.
My footage was shot on a Sony VX 1000 wich records audio in 12 bit, but like you said Premiere captures in 16 bit 2 channels left and right to create 1 stereo track. Ive captured the same way on previous versions of premiere and had no problems with this I'm pretty sure I have everything set up right. These photos might help us solve the mystery.
This is what the clip looks like when placed in the timeline with the "ghost audio track" on the bottom.
This is what the clip info shows when it's in the timeline. Why does it automatically show " 2 stereo " or "audio used 2 times" I only want normal Stereo and I dont know why it automatically uses it twice.
I could do what Ann Benns said and modify each clip but that's still a waste of time.
I've just never seen anything like that. The only thing close to an explanation I can come up with is yet another quirk of Quirktime.

It records 12 bit for 4 channels. Did you record 4 channels?
Premiere captures in 16 bit 2 channels left and right to create 1 stereo track.
For my PDX10, Premiere does not capture 48K audio correctly and I use scenalyzer. For a few cameras in that era, sony chose to write a special marker to define the 4 audio channels that are used, and this marker is not recognised by Premiere.

From the same camera? Using .mov?
The camera itself records 4 channels I believe becuase it's 12 bit, but capturing in Premiere 16 bit so it can be 1 stereo track. Yes I was using the same camera to capture on previouse versions, but this was on a pc so they were .avi files.
Here's a link to someone who had the same problem, same camera and all, no solution here either.
In Premiere the " Default Track Format " is automatically set to " use file " in which the audio for vx 1000 footage is split across 4 mono tracks. Now Ive changed the " Default Track Format" to Stereo I just dont understand why there is two tracks. It appears the second stereo track is from channel 3 & 4 and since adobe doesn't recognize it that's why there is no audio. There should be a way to disalble channel 3 & 4 without having to modify the clip after capture. This seems like a flaw in Premiere CS5, I'm gonna have to see whats up with Final Cut.

That's unlikely. Capture doesn't change anything, it's just a direct copy process. The 1's and 0's go from tape to hard drive "as is".
So if it's capturing at 16 bit, then it must have been recorded that way. And 16 bit allows for only two channels of audio.
But even if it were recorded at 12 bit with 4 channels, PP itself can only copy over the data from the first two channels. It doesn't have the ability to copy the extra two channels.
So..I still think this is a system error, or a problem with QuickTime. You can test that by capturing the same tapes on a PC, where the default file format is AVI.
The camera has two stereo channels in 12 bit audio.
see the manual.
I suspect that's a misprint. I've never heard of a DV camera (carrying the DV logo) that couldn't do the full DV spec, which includes 16 bit stereo.
Having used the camera in the past for multicam shoots, I also don't recall being limited to 12 bit audio.
Yes of course there is a 1 stereo channel in 16 bit, i was only refering to the 12 bit, as OP recorded in 12 bit.
The 12 bit channel can be used for dubbing.
OP recorded in 12 bit.
Well, he said it was coming in as 16 bit, so that's unlikely. Capture won't change the bit depth of recorded audio.
Your link is messed up:
The camera itself records 4 channels I believe becuase it's 12 bit, but capturing in Premiere 16 bit so it can be 1 stereo track.
What is your sequence setting? You should be in an SD 32bit, right?
Did you record on channels 3 and 4? I see no waveforms in your track 2, so I assume you recorded only channels 1 and 2. If so, you should have used 16bit audio.
In Premiere the " Default Track Format " is automatically set to " use file " in which the audio for vx 1000 footage is split across 4 mono tracks.
I would not change that default. The file audio for VX1000 set to 32bit mode is 4 mono tracks. Since that's what you shot, keep that as your sequence setting, capture it as 32bitg, and, if you want, set the audio differently use modify audio.
Premiere audio conforming is using higher rate even if it is 32bit, right? Just export it as you really want it.
I still think you should try capturing on a Windows machine to create AVI files. I suspect something is off with QuickTime.
