Infoseite // strange audio problem with the capture of sony-cam



Frage von jeanmartin:


Hello,

following phenomenon:
(we) a few students have a meeting with 3 cameras filmed. One of them is a SonyDSR-PD150P. To these we have 1st a stereo condenser micro and 2 Press the output of the sound system (XLR) is connected. This has recommended to us by the competent camera expert: if the XLR signal fails, we still have the (lower) Micro-signal.
So far, Sogut.
This has worked wonderfully. When playing you can with the on-screen menu to choose whether to channel 1, 2, or both mixed wants to hear, that works! Synonymous. However, we try to capture the images via Firewire, we get only _eine_ audio track (and the time is mono, stereo views!?). Highlight: No matter what channel we choose s.Camcorders, there will always only channel 1 (or a mix of 1 & 2, we disagree) captured. Were purchased specifically for capturing IBM Thinkpad, on which is installed Premiere Pro 1.5.

What we have already tried:
- Premiere searched for appropriate settings. Nothing suitable found
- Other Capture program tried (Movie Maker - I know ^ ^) the same problem
- Tried another PC
- FireWire cable replaced
- Instructions scans of the camera, no useful information
- Another small camcorder [SonyPC-103E] (in which we have no possibility of channel-Auwahl have found), tried

All without success. Help!
(yes, the camera's expert could not help us by telephone and is now in the U.S. ...)

Thanks for any suggestions!

Sincerely,
January

Hello Jan,

You need a capture software that can capture synonymous channels 3 +4, eg

Antwort von jeanmartin:

Hello and thanks Mark

as audio mode, we've got set Fs48K (16 bit). According to instructions included, this means high-quality sound on 2 channels only without the possibility of additional sound on channels 3 and 4 ... ahaa.
Why are but different channels used for playback and s.Camcorders via the FireWire output?
Why not in the instructions? Why can not the premiere? Are there any free tools? VirtualDub can it? (I already own search ^ ^)

Yes, the questions were rhetorical in part.

The sound was indeed placed on the two channels 1 & 2, I was able to fine-tune it during the recording () is applied. Otherwise there was nothing to check. When I look at the recording s.Headphones directly s.der Camera and listen for example, only activate Channel 2, I hear the left and right, but whether it be stereo or mono only twice, I dare not judge. It is synonymous no preference whether it be mono or stereo recordings, but simply has the Micro Signal (Channel 1) to be switched off.

Regards,
January

Antwort von Markus:

Hello Jan,

If you have recorded in Fs32K, then there definitely are only two channels. One channel will contain the signals of the microphone and the other channel, the signals of the sound system. In this case you need any additional capture software, but choose later in post processing with the left and right channels, ie the sound from the microphone or the sound of the plant.

What I would be interested but still: How did you two times of the stereo XLR microphone and one (or two?) XLR Female of the plant s.The two XLR connectors of the PD150 connected?

Antwort von jeanmartin:

Hi Mark,

ok, and in Fs48K (what we used) are so sure the channels 3 and 4 used for the transmission to the capturing, yes? I want to make sure that I understood correctly. The problem is that depends on capturing only one channel, so that later I can choose no more ...
How do I see in a program, whether it can mitcapturen synonymous, these two channels?

erm .. yes, of course, only a time of micros in Input 1 and one XLR cable was 2nd s.Input The mono / stereo question would then be clarified yes ^ ^.

Thanks once again for the quick help. January

Antwort von Markus:

Hello Jan,

the sound is stored in the channels 1 +2. The channels 3 +4 is found only in Fs32K mode (12 bit).

That you in capturing just get a WAV file is normal. This file includes a stereo, so the two individual channels 1 +2. Then came the playbacks of different sources, this is obviously not a true stereo sound, but that is not so important here. The recordings can capture initially synonymous as any other recordings.

In Premiere, you import the clip and dragging it onto the timeline. Now you click with your right mouse button on the soundtrack and choose from the Audio Options menu> Duplicate or duplicate left channel, right channel, depending on which sound source you want to have.

Antwort von jeanmartin:

Hi Mark,

pity. We thought it would ...
Unfortunately, is exactly the problem. I'm getting _eine_ mono track.
I had the time synonymous gecapturte file open in Audition, no doubt. In an experiment (do not ask) was actually why stereo captured, the two channels were synonymous different, but it was not, unfortunately, that one of the (bad) Micro-signal and the other the good included XLR signal! Both were in the bad micro quality.

Perhaps you notice (or someone else) a little more, as can be.

Regards, Jan

Antwort von Markus:

Hello Jan,

a remote diagnosis is always difficult, but I still have two ideas: On the XLR sockets of the PD150, various audio switch. With it you can set, if channel 1, only to be recorded on channel 1 or simultaneously on channels 1 +2. In the latter case would be the second XLR playback (of the plant?) Was not recorded with. Both channels would be an identical (mono-play) microphone signal.

Another idea: When the shooting were both XLR Male (left and right) of the stereo microphone has been connected and the management of the plant was inadvertently overlooked anyone ...

Antwort von jeanmartin:

Hi Mark,

Unfortunately, neither of these, at least that we've taken. When you play the sound directly s.der Camera, you can choose between the two channels, and actually listens on the one hand, the Micro and on the other hand, the XLR signal ...

Thanks anyway;) Jan

Antwort von Markus:

Hello Jan,

Unfortunately? - I would say, well it was not a host problem. Otherwise it would be nothing left to save! - What is not evident to me, however, why the capturing of a standard recording only one of the two channels will be read?

What have you got set parameters for audio in Premiere?

Space


Antwort von jeanmartin:

Hi Mark,

Of course not "unfortunately" ('m already tired ^^)...
'm not quite sure what exactly you mean:
The premiere of Project:
- Samplers Rate: 48000 Hz
- Display Format: Audio Samples

Sequences:
Standard sequence
Video tracks total: 3
Nature of the master track: Stereo
Mono tracks: 0
Stereo tracks: 3
5.1 Traces: 0
Submix mono tracks: 0
Submix stereo tracks: 0
Submix 5.1 tracks: 0

The sequences are not only a matter of display?
I do not synonymous know where there might be more settings in Premiere, with whom I influence the capture.

The stupid thing is that I do not with the camera can take home, so I can not test fast. * angry *

Is it normal) (right that the setting (in VCR SET - Menu of the camera), which channel is playing, has no effect on the gecapturte audio signal? Then I shall not try it with different combinations.
If you do, I no longer looking through, because synonymous if channel is set to 2, only channel 1 is captured.

In case you well versed with the Camera: Are there any stupid settings that we could have possibly done to explain this behavior? Respectively.: In what settings we need to pay?

Thank you for the effort! jan

Hello Jan,

This is not so bad. If you have filmed in DV mode, the tapes can be synonymous of other MiniDV camcorders can be played. DVCAM, however, can only play a few MiniDV devices.

Well, have you answered the question yourself! ;-)

There are, of course, in the recording settings that have not brought the desired result. This I have queried in the above contributions, however. Otherwise, I find synonymous anything any more.

My question about the audio settings related to the capturing. Yes you can when you start a new project to make various project settings. Please look at audio, what are you captures (mono / stereo)?

Antwort von jeanmartin:

Hi Mark,

where do I select what I want to capture audio? I find no setting for Premiere, which might mean. The settings of the sequences, but is only for display and there is no influence on the capture!?

Here is the Create Project dialog:

Antwort von Markus:

Hello Jan,

I just again in Premiere (6.5, however, looked) ... because there are no other controls that you would help s.dieser place. But why the bilingual should be saved from the camcorder via firewire only in mono on the calculator?

Perhaps once you try on a capture tool such as

Antwort von jeanmartin:

Hi,

Good news:)
Must be a real problem in Premiere. We have tried the following:
Capture with Premiere, then open the AVI in the audition shows a remixed mono tracks.
Capture with Scenalyzer, then open the AVI in the audition shows two traces. Separate
monitor displays, a microphone is to trace the other, the XLR-track ... perfect: o)

So thanks for the help!

Many greetings. January
