Hello COW Members! I've been helped many times by the Community. I'm stumped on this audio issue and I'm in the need of some experienced help.
I'm on PP CS3, I've digitized Video with two different Mic sources (Lavelier on the Left Channel, Shotgun on Right Channel) Video picture and channel 1 are clear and looking good, Channel 2 however is another story. There is VERY low sound or there is NO sound whatsoever in some clips... Upon checking the raw .AVI files it seems to have been captured that way.
My Edit is in a Standstill, Thy Client awaits...
I've checked all my hardware, tried multiple cameras, Firewire cables etc. I feel I've isolated the problem down to to the point of capture.
Now when digitizing using windows movie maker it does the same thing- Which leads me to the firewire card, not the program that i capture with...
Some Facts:
I'm digitizing to an .AVI Codec.
Video card: Nvidia Quadro FX 540
Firewire Card: VIA OHCI Compliant IEEE 1394 Host Controller
Audio Card : Realtek High Definition Audio card
I've have collected some posts with very similar problems...
I Trust that Premiere Pro CS3 can provide professional two channel audio input through firewire for editing, its got to be something I'm doing wrong. I have other editing options (FCP, AVID) but I want to fix this so I can add Premiere Pro to my editing platform arsenal. (plus, The Dynamic link to AFX is GREAT, can't get that on an AVID!)
Re: Audio Capture Problem - No Right Channel by Vince Becquiot on Jul 8, 2008 at 9:34:58 pm
Well, then I can only conclude that it's how it was recorded. The signal is digital, so if it's there, it has to be in the same state as it was on tape. The capture software can't really alter its volume, neither can Premiere, until it's sent to the timeline.
If you play back the tape with headphones on the camera (separate channels on left and right, not mix), is it really matching in levels ?

Thanks for Help Vince-
The audio was recorded fine, The levels are almost peaking on the Camera audio level monitor and DVcam Deck monitors... There's ALOT volume there.
I've tested the tape in multiple decks and camcorders and i can hear it in the headphones coming out of PDX-10 Loud and clear...
I'm going to try and Digitize this Material in an Edit platform that I am confident in... If I'm getting the same problem there - Its definetly the recording of the tape.
But if its not, I'm still not giving up... There are too many people out there being plauged by this problem and working around PP.
If you could just humor me and tell me that it is possible to record Video and two track audio in to PP... I just need to verify my sanity.
Is there ANY way that i could prevent Audio 2 from coming through the firewire?

I predicted the camcorder model from the subject line...
I have a PDX-10...I absolutely love that little thing, but this is the issue right here...the FW out on that camcorder has an issue coming out as two channels over FW...I've had the problem in every version of Premiere since I bought the thing.
Most cameras have absolutely no problem outputting 2 channels of sound over FW...there is no FW problem of that sort in general, but the PDX-10 does have an issue with that.

Thanks for replies...
Maybe its the PDX-10...But I've had the Same Digitizing problem in three Separate cameras. a Canon GL2, The Sony PDX-10, and some tiny consumer handheld that i can't name at the moment.
I also made sure that i chose the right model in the settings tab PP CS3 has a preset for both the Canon and the Sony.
Could my Audio card be the culprit?
Side note: I just put the footage into Final Cut Pro. Everything is there. Tape Source gets 100% OK. I could slice this thing up right now, but I'm still pushing for answer.

If it works in FCP, I'd cut it there...
i don't own any Canon camcorders, but I've tried any number of ways to get the audio to come into PPro correctly from the PDX10...(it honestly is one of my favorite pieces of equipment)...I've had no luck.
Adobe has reproduced the problem...about two versions ago.

Thank you for your input Tim. The PDX10 is a great prosumer camera.
How do you get your footage successfully into premiere pro CS3, If may ask?
Due to the fact that I used three different cameras, and then digitized from windows movie maker with the same result --
Not only would I have to rule out the PD-150 but perhaps PP CS3 as well? would you agree?
Re: It's the PDX-10... by Tim Kolb on Jul 9, 2008 at 4:34:49 pm
I only run one channel of audio on a PDX10.
I really don't use it as an A-cam. Its size makes it work well for small spaces, though it's light hungry and doesn't do low light particularly well...
...wish I had a better answer. Sorry.
I still love that thing though...so compact and versatile.

I had the same problem whit my pdx-10, so I made some test, recording audio on individual channels, on all possible modes and formats.
The result was:
DV SP audio 32K (12bit) both channels captured fine.
DV SP audio 48K (16bit) only captured Ch1.
DVCAM audio 32K (12bit) both channels captured fine.
DVCAM audio 48K (16bit) only captured Ch1.
I captured the material with a Sony GV-HD700 deck, tried material recorded with other cameras, and in all those cases captured both channels fine.
So, if you need both channels, should start recording at 32k, or capture it via the analog output for the old material.

Have similarly been plagued by this problem and resorted to using 12 bit only for capture when using 2 mikes but today I was working with a sound guy using Mac and Final cut pro and we did a test with my PDX 10 and the stereo audio came through perfectly
I wonder if there is something I need to change in the Windows XP system I am using.

As a fellow PDX10 owner I have also felt the two channel pain for years. When I have to use both channels. I capture the tape with Scenalyzer. it's not as slick but does the job.
Re: It's the PDX-10 or is it premiere by Dan Roesch on Jul 25, 2008 at 8:56:35 pm
It does it's own thing. I wonder if you could do your capture in Scenalyzer, unlink all your clips in premiere and then relink each clip to its new counterpart. Certainly time consuming but perhaps easier that an entire re-edit.
Even more idealy would be to set up your naming convention in Scenalyzer to create identically named duplicates and then hide the original files. The next time premeire asked to find the media you could point it to the new clips. I don't know if that would work or not. If I have some time this afternoon I will run a test.
