FCP capturing audio in mono

Hi,
I've just captured some footage that I filmed earlier, and FCP says that it's a mono track, and I checked the camera, and it's set to record in stereo.
Any thoughts.

hi david
is there any way of recapturing the clips in stereo, using the settings in your log and capture window?
i have gone through a bunch of tapes logging and capturing maybe 6 hours of footage, only to find that they come into the timeline with 1 video and 1 mono audio track (left). now if i could edit the log and change the setting to stereo, maybe i can recapture without the need to log everything again.
hoping...

FCP Capturing & Audio

I'm working with FCP 4 (purch. upgrade on Amazon - I know, I know I'm working in the dark ages), and can't hear audio thru my speakers when capturing; however the audio meter registers sound, and there is sound when playing back the clip after capture. I've been working with an even older version of FCP, and it plays audio thru my external speakers while capturing. Was this feature removed in newer versions of the software in order to eliminate some sort of problem? Or, is there an audio setting I'm overlooking that allows audio playing while capturing?
Any info would be muchly appreciated!

for versions prior to 5 you have to edit your Capture Preset:
Final Cut Pro > Audio/Video Settings > Capture Presets > Edit > Quicktime Audio Settings > Advanced > Speaker On

Capturing audio from telephone for use in FCP

My requirement is quite specific, and so far none of previous posts seem to answer my question. So...
I'm looking to capture audio from my telephone for use in FCP. It won't be a telephone conversation, but a voice text. In other words, an SMS sent to a landline. The audio is saved as a voice message on the answer machine. My phone / answer machine is fairly basic - it has a speaker and the only ports it has is for power and the telephone line itself. I have tried a very basic method of playing the message on speaker and capturing it on a mini DV - but that results in too much audio edit to get it to sound acceptable. My Mac is a G5 and I have the full FC studio, but just not sure of best way to get audio onto the Mac without losing too much of the sound quality.
Any suggestions?
Many thanks all...

you need a telephone audio interface like the products made by the fine folks at gentner, telos or jk audio. i have a celltap from jk audio, works very very well. http://www.jkaudio.com/celltap.htm

I cannot capture Audio

MacBook Pro 2.33 GHz
Final Cut Pro 5.1.4
Quicktime Pro 7.1.5
JVC Camcorder GR-DV4000E
Connected via firewire direct to the MacBook
I have reinstalled Quicktime and trashed the FCP preferences.
When I go to Audio/Video settings>Capture Presets and edit my DV PAL 48 kHz settings under Quicktime Video Settings I get [Missing] DV Video and under Quicktime Audio Settings [Missing] DV Audio.
In the digitizer menu under Quicktime Video Settings there is an item DV Video. If I select DV Video it does show next to input my camcorder (GR-DV4000). But when I select DV Video, there is not anymore a setting DV Audio in the menu under Quicktime Audio Settings (not even the [Missing] DV Audio setting).
This behavior does not change if I select View>Reset AV Devices.
I can capture video, but though there seems to be an audio file, it is silent. If I select Show Audio Waveforms in the timeline, there is no waveform visible. The viewer does have a stereo tab but it shows no (visible) audio waveforms.
In System Settings, Capture Audio and Video to Separate Files is disabled. Enabling this does not make any difference.
Is this a known bug? Anything I do wrong? Anything I could try?

Were the capture settings and any other settings the
same for your test with the powerbook?
Have you successfully captured on your macbook pro
prior to your current problems?
If so, have you made any changes to your system,
software updates, system updates, Third party apps or
plugins?
In your original post you mention that though
there seems to be an audio file, it is silent
what exactly does this mean? Do you get a green
audio track after capturing, but it is silent? Is
there any movement in the levels meter (next to the
toolbar)? Is there definitely audio on the tape(s)
in question (do you hear it playing it on the cam?)
Do any other tapes work?
When I originally asked what the capture settings
are, I was wondering if you have set FCP to capture
audio from Ch1 when it was recorded to Ch2 on the
camera i.e are you capturing audio 'Ch1 + Ch2', Ch1
(L), CH2 (R), 'Stereo', 'Mono mix'?
The Capture settings were exactly the same.
This is the first time I try to capture on the MacBook Pro.
I used the migration assistant to transfer my software on the Powerbook to the MacBook Pro.
I get 4 green audio tracks that are silent. There is no movement in the audio meters, nor on the timeline, nor in the capture window.
There is audio on the tapes. I have captured 11 different tapes that are all silent. Everything works on the Powerbook. The sound on the tapes is 16 bit stereo. Capture was set to record Left and Right linked as a stereo file.
I think this happens because I cannot select DV Audio in the Audio/Video Settings.
The strange thing is that I get [Missing] DV Video and [Missing] DV Audio in the Audio/Video Settings. In the menu under Video Settings I can select DV Video, but when I select this, there is no more DV Audio in the menu under Audio Settings.
The tapes were captured with [Missing] DV Video and [Missing] DV Audio. This captures the video but not the audio.

Strange export result in FCP 7- audio and video output not in sync anymore

I have a problem exporting edited videomaterial. After export audio and video they are not in sync anymore. There's a difference of 8 sec when exporting audio and video separatly. Movie is total 61 min long.
Video and sequence settings are HDV1080i50, 25fps, 48khz, 16 bit, mono.
What could that be ?

Well now that I look at all the clips in FCP more closely I see some clips from the same tape are in sync and others are out of sync. And one section of tape which I captured twice was in sync on one clip and out of sync on the other. So it can't be the tapes.
Maybe the sync problem is caused by not coordinating the tape playing and FCP capturing properly every time! So I will try re-capturing the problem sections of tape.

Unable to capture audio from BlackMagic HD Extreme via Voice Over tool

Hi !
I'm trying to capture audio via my BlackMagic HD Extrem card using the Voice Over tool in FCP6, but I can't, no audio is incoming.
I can ingest audio with video using log and capture, then I know my card and my cables are working.
I tried to set the BM card as audio input in my Audio's System Prefereces Pane, but it isn't working either.
I've been looking on the BM website, but I found nothing.
Can you help me ?
Thx

Thanks for the reply.
Looking at system preferences I found that audio input was set microphone. Don't know how it happened. I switched it to DeckLink and now FCP displays 16 input channels in Log and Capture dialog. I didn't try to capture yet but I think it solved the problem, because before I had only two channels displyed.

Capturing audio only in fcp5

I am rather new to Final Cut Pro 5 and have been trying to teach myself as I go along. I am, however, having trouble capturing audio seperate from video. I am shooting a 16mm film and need to capture audio and video to seperate files in order to synch them for edit. While I am able to capture straight video (i.e. without audio) I am unable to capture straight audio (i.e. without video in the same file). The only way that I have been able to capture audio is if some form of video is captured along with it. How can I capture an audio only file. I am using FCP 5 on a PowerBook G4 - capturing through a "Dazzle Hollywood DV Bridge" with a Canon ZR 45 for video and a Sony TCD D8 portable DAT for audio. Any information is greatly appreciated and I patiently await your response(s).
Thank you,

My welcome also but, as a beginner, you really need to run the tutorials and learn how to use the resources you paid for when you got your applications.
Look in the online help system for audio only. Look in the manual index for audio only. Examine the chapter on capturing.
How are you doing Video Only if you don't understand the Clip Settings function or where it is located?
You can force DV to build separate audio and video files while capturing but it's not recommended (dunno why not). If you force separate files, you can simply delete the ones you don't want.

Capturing Audio from DAT

Hello,
I'm trying to capture audio from a DAT deck (Tascam DA-20) into FCP HD by routing it through my JVC BR-DV600U DV deck (RCA output from DAT, RCA input to DV deck, Firewire into FCP).
The DV deck's input is set to line-in, and the audio is being routed through (audio meters on DV deck mimic those on DAT deck, and I can hear the audio through the headphones jacked into my DV deck).
However, when I try to capture the audio on FCP, I am unsuccessful, prompting the following window from FCP: "Error: Final Cut Pro HD was unable to read the movie file just captured."
Now, I use the same set up I described above to capture footage from my Beta deck into FCP with no problems (route Beta signal through DV deck and firewire it into FCP). This leads me to believe that perhaps the glitch lies within my Capture Presets.
At first, I tried to capture the signal as an Audio-Only DV NTSC 48 Khz/Non-controllable device. After that failed, I tried to create my own capture preset, but am not sure it will make a difference, as the only input choices I am given are DV Audio, Built-In Audio, and None.
Any suggestions?
Thanks.

Why not capture the audio content outside of FCP, check the sample rate for 48Khz/16-bit, convert if necessary, save as an AIFF file, and then import that resulting sound file into FCP?
Any good audio app, including STP will do captures.
You are probably going to need to do some cleanup on the audio anyway before you use it, so why not just use an audio app to do it beforehand?
Besides, if you have an audio device (PCI card or Firewire device) in your Mac, you can use the S/PDIF port for your connection to the DAT and do a digital transfer when you import.
As I understand the way you are doing it now, you are taking digital content from the DAT, converting it to analog for the connection into your deck, and then re-converting it into digital when you capture it back into FCP.
One big advantage of digital audio (and video) is to avoid generation loss and added noise during transfer if you go D-to-D.
If you don't have an audio card or Firewire A/D audio I/O device with S/PDIF ports in your Mac, then see if you can find a friend who has one and can do the transfer for you. Then he can give you the file on a CD-ROM.
That's what I'd do.

A/V out-of-sync issue for FCP captures

I've read many of the out-of-sync posts on this board, most of which seem to indicate that the problem is usually caused by either dropped frames, bad timecode breaks, edit errors, or disunity between FCP capture and sequence settings, compared with audio sample rates for the underlying files.
My files, shot on my Panasonic AG-DVX100A in 24pa mode, result in perfect (except for the anamorphic screen size - see my next post!) Quicktime movie files, in perfect sync. It's only when I create clips from those files in FCP that the video and audio go out of sync. And the out-of-sync drifts; that is, the further you go in the clip, the more out of sync the sound and the video gets.
My camera is always set to the 24pa mode, which, by default, records only in the non-drop-frame mode, regardless of any other camera settings I may have selected. The audio settings in my camera (and in the resulting underlying QT files that are created when I capture in FCP) are 16-bit integer and 48.000 khz, as they are in both my FCP sequence presets and capture presets, so I don't think it's an issue of conflicting sample rates. My device control presets are for Firewire NTSC NDF (non dropped frame).
Given the above information, does anyone have any idea what else I might be doing wrong? I've already shot hundreds of hours of footage last year that worked fine. I don't know what I changed to cause this out-of-sync problem now, but I'm going bald tearing out my hair trying to figure it out.
Thanks in advance for your help!

The dvd recorder was in the loop when the sync issue showed up. the dvd was in sync but the live stream, next in line, was out of sync. I have returned to using the older machine with xp. (the lap top is running vista) The older machine is a desktop which requires more space on the production table and time to set up.

Problem capturing audio

Hello!!
I am trying to capture audio using jmf 2.1.1.e in Linux (SuSE 8.1) with jdk 1.4.2_04. I have "alsa" properly installed. However, when I try to capture using jmstudio, I am shown "javaSound audio", LINEAR, 44100 Hz, 16 bits, stereo, little endian and after cliking OK I get :"Could't initialize the Capture Device".
I also try to run a code to capture audio, using the following:
Vector audioDevices = CaptureDeviceManager.getDeviceList(new AudioFormat(AudioFormat.LINEAR, 44100, 16, 2));
CaptureDeviceInfo audioCDI = (CaptureDeviceInfo)audioDevices.elementAt(0); //I get javaSound
ds = Manager.createDataSource(audioCDI.getLocator());
processor = javax.media.Manager.createProcessor(ds);
But I get the following exception:

Could you be so kind as to help me, please???
Thank you very much in advance.

Hi wew64.
I m new to JMF. I just made a simple media player not any more. can you please tell me what is "alsa" and "arts".
actually I want to control my Sound card properties like "Microphone, Line In, etc...." is it possible in java if it is please tell me.
I will be very thankful to you
I m very upset about it because it is minimum 3-weeks late, my project is pending on this stage. All i want to do, just to mute the volume of "line in" (property in my sound card, which takes audio data from a TvTunner card and leaves this audio data out to the speakers.)so that only the audio from my computer's( any application like media player) can goes to the speakers, not the audio comming from the TvTunner(My TvTunner is opperated by the application provided by the vendor, I did not develop this on my own in java. I just made my media player in java). Yes this is the PROBLEM that both audios from TvTunner card and from My Application are being transmitted to speakers simultanously. But i want, when my application is running, the audio comming from TvTunner should be muted and when my application is exited, the TvTunner's audio should be unmuted. And this is only done by Line In property because Audio from TvTunner card is got by the Sound card through the Line In property.
I tried my best to find out the solution but could not get any thing right.
Please Help me
thanks

Can't capture audio in stereo pair

I have FCE HD 3.0 and the audio capture default has always been stereo pair. Just now, since having to trash preferences, the default capture is now mono. Thanks to the forum, I know how to modify>link stereo in the timeline, but could anyone explain how I could reset preference to capture audio stereo?

You can't.

How do I capture audio only, no video?

I'm trying to capture an audio cassette, patched RCA/XLR to a Kona Card, to a G5 tower running FCP6. Since I want to capture audio only, I unchecked the video box in the clip settings tab of the LogCapture window. But when I capture now, I get a message saying "This operation could not be completed as there is no video".
How can I capture audio only? Can't turn off the video in Kona ctrl panel, must be in FCP.
Thanks in advance for the help.

Yes, as I mentioned, I did uncheck that video box, after which I got the message 'operation could not be completed as there is no video' (& capture failed). My capture setting is to Kona, but I've also tried Generic, but no luck.
This then led to my first crash course in SoundtrackPro, which is now recording the audio I needed. But I would love to figure out why FCP is not letting me capture audio w/o video, so any further suggestions are appreciated.

Does Logic 9 Support FCP Capture Cards?

Does Logic 9 support FCP video capture cards for audio in an out?
I have a Blackmagic Decklink Extreme, analog ins/outs as well as digital AES/EBU
Didn't have much luck with Logic 8 and the FCP cards so I used my Line 6 GuitarPort but it only has one 1/4" phono input.
FutureX

Hi FutureX,
I would suggest you ask your question on the FCP forum if you don't get any reply here. Maybe you'll find someone there who can be of help. In any event, i doubt that buying an MBox with PT LE will meet your requirement for FCP capture cards, really!
Apple won't respond to you here. That's not the place. This is a user forum. You could also call a production studio in your area and ask politely to a pro who's working with that stuff on a daily basis. I'm sure you can find someone. Good luck...

FCP importing SDHC media mono in stereo

Hello !
I've got a small issue. When importing files from SDHC card with video and two audio channels MONO, FCP in the monitor window, create a stereo file. I can't split them.
This is annoying as generally I've got an interview on channel 1 and Camera microphone (noisy) on channel 2.
How can I put them back in 2 separate mono channel ?
Of course I can put the mono channel in the timeline and work like that but should have a solution to do it directly into the source window, no ?
Thnaks !

You can put it on the timeline, remove the stereo pairing (Option + L when it is selected on the timeline), delete the channel without audio, then double-click on the clip on the timeline to send it to the Viewer/Visualiseur to put your markers in and delete it from the timeline. Be sure to make a new master clip if you want to leave the project and return to it with the markers.
Easier perhaps - at the end of the edit delete the audio layer with the on camera microphone, then use paste attributes to pan all of the audio channels to center. It would drive me crazy to do it this way because the audio will be messed up while you edit.
