How do I capture at an audio sample rate of 44.1 KHz?

Hey,
I'm wanting to capture some footage that's been recorded at a 44.1 KHz sample rate. Presets on FCP 5 only have 48 KHz.
How do I change this?

I just checked the import settings on two other editing systems I use... Canopus DV Storm II and the Matrox RTX 100 Extreme. Only the Canopus has a preset for 44.1k import. Even Adobe Premiere, using the native IEEE 1394 connection, doesn't have it. I am not sure if FCP has a "CUSTOM" import dialog that might allow you to manualy select?

How can I find out the audio sampling rate of BetacamSP tape?

Hi guys
I'm trying to digitize BetacamSP tape. But I'm afraid if I might choose wrong setting...
This tape is from very long time ago so we don't know which audio sampling rate we recorded with..
How can I find out the audio sampling rate of this BetacamSP tape?
Thanks:)

The sampling rate is set by the Sony DVMCDA2 you are using, when the conversion is made from the analog input to the digital (DV) output. You should be outputting standard DV which is 16bit 48khz audio.
Assuming you are in the US, your Easy Setup for FCP should be DV-NTSC, and then open the Log and Capture Pane and set the Capture Settings Device Control to Non-Controlable Device and you should be good to go.
You will have to roll the deck manually and start and end your capture manually.
You can download a user manual for the DVMCDA2 by clicking here.

How do I determine that my audio sample rate matches my tape?

How do I determine that my audio sample rate of my capture preset matches the sample rate of my tape?

You've really got two issues.
DV records audio and video differently and if the camera is substandard, you will have drift over long captures. Solutions: new, better camera or capture in small (max 10 minutes) chunks.
The other issue is the 32k sample rate, which will exacerbate issue 1. You can duplicate the 48k preset and modify the copy for 32k and work in that until you are ready to deliver. Then copy it into a 48k sequence, render and output.
It's funny, sometimes I get that pop up but everything is fine.

How can I ensure that the audio sample rate of my capture preset matches?

Hi
1. I have found that none of my ten projects has sound, although audio meters & settings moves up & down.
Simultaniously, canvas displays that In: Not Set- & Out Not Set. Below those reads: Video V1: 00:03:42;13 Audio A1: 00:03:42;13 A2: 00:42;13. These happen on the images of all my ten projects when the playhead stops in timeline
2. In Viewer the In & Out sets show a thin red line connecting them.
I never had this problem before. A/V of all projects were doing just fine till last night.
I wonder if these issues are interrelated, or if I may have clicked something wrongly that has triggered this, which I don't remember now.
I would appreciate it if you could kindly address this problem and help me to resolve the isssue. Thank you. Faruk.

The red line indicates the audio must be rendered. This may be caused by several things but your playback settings may be set too high for your system to handle. You may have too many audio tracks for your computer to play in realtime.
Select one of the audio files in the timeline, get properties, not the audio format and sampling rate.
Now got to Sequence>Settings and determine if the settings match your audio settings.
Your online help system can guide you through adjusting your system settings, user settings and sequence settings.

Audio sample rate stuck on 32 kHz

This just started happenning recently. Any audio I output over firewire is 32 kHz. I can't chang it. All the FCP presets are set to 48 kHz, I never use 32 kHz for anything, and yet all of my DV decks automatically switch to 32 kHz when I connect them to the firewire and open FCP. I have 2 other FCP systems and they work fine. It's just this one. The computer is a G4 Digital Audio and I'm running FCP3 on OS9.2. It had been working fine, but I must have done something, and I can't figure out what. Any ideas??? Thanks.

Ended up having to reinstall Final Cut. That was the only thing that was able to fix it.

Determining DV tape audio sample rate

I have DV tapes of "archived" final edits recorded on to mini DV tape using two "early" (late 90's) Sony DV cameras with some segments of the same tape recorded with 48k audio and other sections with 32k audio (on the same mini DV tape). I tried to capture the footage into FCP 5.1.2 using a Sony DSR-11 deck and a G4 1.42 GHz dual processor w/ 2 gigs RAM, Radeon 9800 Pro video card, Mac OS 10.4.8
Everything seemed fine until I got a message after capturing a 3 minute clip using a stock FCP 5 NTSC preset with 48k audio; the message stated the "audio source rate and capture sample rates did not match & footage may be out of synch" - the captured clip played back perfect. The DSR-11 did not display the DV tape's audio sample rate; I put the DV tape into the camera it was originally recorded on and "16 bit" displayed on the camera's LCD screen.
I tried capturing the same footage using FCP 4.5 installed on another drive in the same computer, and got no warning message re: audio sample rate. Just to "be sure", I created a custom capture preset that included 32 bit audio and captured the same clip using FCP 4.5 with a preset for 32k audio - no warning message, and everything was perfectly in synch. Everything was in synch for ALL the captured clips & the audio sample rate in FCP for captured footage was either 48k or 32K for each respective preset.
The dilemma: how to be certain what the true/original audio sample rate is.

"audio source rate and capture sample rates did not match & footage may be out of synch"<<</div>
William,
The message itself seems to be a bug that started with FCP 5 - most users that receive this message have reported that there is NO actual problem.

How can I ensure that the audio sample rare of my capture preset matches?

Hi everyone
When capturing tapes I get warning that the audio sample rate of one or more of captured files does not match the sample rate on my source tape. This may cause the vidio and audeo of the media files to be out of sync. How can I make sure that the my capture preset matches the sample rate of my tape? Can anyone be able to show me how? Thank you. Faruk.

Hi
Fuerther, I have double checked and found that none of my ten projects has sound, although audio meters settings moves up & down. Simultaniously, canvas displays that in- & out of clips are not set , and in browser I see time codes on the images when the playhead stops in timeline. I did not have this problem before. I wonder appreciate if if these issues are interrelated, and if I may have clicked something that has triggered this.
I would appreciate it if you or other friends could kindly address this problem and help me resolve the isssue. Thank you. Faruk.

Change capture settings to 32k audio sample rate???

I have a DVCAM tape that my client recorded and the audio sample rate is 32k. I have noticed that the audio seems to get out of sync when I capture it using the 48k NTSC. I also get a warning saying that my source tape's audio sample rate doesn't match the capture settings and that audio could be out of sync. I looked at past posts and it does seem to be the 32k verses 48k.
My question is how do I change my capture settings to 32k? I see how you do it on the sequence settings, but I can't figure it out on the capture settings.
Thanks,
John Schenkel

John,
I recently read a post where there were four likely answers to the problem, yet I was not sure which one was the best solution.
Why? Because even though the question was marked as answered the person posting the original question didn't mark which individual's answer was the solution.
Please help future users to find answers more quickly, who knows, you may find yourself in the same situation someday.

Capturing issues-audio sample rate & locating timecode break

I am a first time FCP user.
I am working on an educational video with hours of DV source tapes.
The source tapes are from a 2R50MC Cannon mini DV camcorder also used as the deck I am capturing from via firewire. My scratch disk is Maxtor III 500GB external drive hooked up via a firewire (I'm realizing the firewire is years old could that be a problem?)
In my first capture test I captured 1 minute of tape by setting in and out points and after completeing the capture I received an error message—"The audio sample rate of one or more of your captured media files does not match the sample rate on your source tape. This may cause the video and audio of these media files to be out of sync. Make sure the audio sample rate of your capture preset matches the sample rate of your tape."
For the past day I have been scouring the user manual, this discussion group and training tapes from Lynda.com and can not resolve this issue. I have determined that the source tape is 12 bit or 32 kHz and yet can not find a way to set up capture preferences to 32 kHz. Is this the problem/resolution? Page 320 of the user manual shows the QuickTime Audio Settings dialog box but I can't find it in FCP or Quicktime. Is this where I make the change to 32kHz?
After doing the first test, I tried again and ran into a new problem—it stopped capturing with the message: Locating timecode break [press esc to abort]. It never seemed to resume capturing and I pressed escape to abort. If I'm reading FCP time code window correctly I received this time code break message within a section I had already captured previously (with the audio sync warning).
I have done several capture tests at different points in the tape and on different tapes all with the same results. I've used the capture clip and capture now buttons. I've tested with drop frame turned on and off. Confirmed my setting of: At timecode break "Make New Clip." Confirmed my Easy Setup as DV-NTSC. My capture preset is DV NTSC 48 kHz. I've turned off and on FCP. Restarted my computer. Restarted my computer with the shift key down and ran permissions.
Any ideas are GREATLY appreciated, T.

I am concerned about available memory when capturing to my hard drive and the babysitting and extra steps involved considering the amount of tape I want to capture...but it does work that's GREAT!
This is always a concern, but in your case I think having the camera and external on the same bus was causing your problem. You may have to capture a little and then transfer, rinse and repeat. Just don't try to do too much at once and let your System Drive get too full, you'll run into other problems there. Slow and steady is the pace!
I shouldn't have stacked my questions since you answered one and Chris answered the other. Don't know how to apply the answered question and who gets the points.
No problem, just mark it answered and divide up the solved and helpful points as you wish. All in all we really don't care too much about the points, but they do make us feel good! Thanks for your desire to use the forums properly.

Capturing-audio sample rate

I have fce hd v 3.5. My camera is a sony dcr-trv11. I am trying to "capture now" but it looks like I am dropping frames. When i hit "esc" it stops capture of course, but I get a message that reads "the audio sample rate of one or more of your captured media files does not match the sample rate on your source tape. This may cause the video ans audio of these media files to be out of sync. Make sure the audio sample rate of your capture preset matches the sample rate of your tape." Okay, so how do I do that? When I originally captured my footage with imovie I had no problems. I had trouble importing them to FCE so I scrapped them all and decided to start from scratch with FCE. I have 199.5 GB of free space.

Most miniDV cameras can be set to record audio as 12-bit or 16-bit; and most of them come set to 12-bit as the default.
Your preset (easy setup) in FCE has to match both the video & audio setup of your camera. Normally, you would select the DV-NTSC easy setup in FCE, which would give you a sequence that expects DV-NTSC video and 16-bit (aka 48KHz) audio. If your video was recorded as 12-bit (aka 32KHz) audio, but you captured into a 16-bit (48KHz) sequence in FCE, that would give you the mismatch.
Check your camera - if it was set to 12 bit audio for the tape you are trying to capture, then in FCE you should select the DV-NTSC 32KHz easy setup for your sequence before you capture your tape.
There are many different reasons you might be getting dropped frames - can you tell us more about your exact setup, esp. if you have an external HD connected to your system. Oh, and by the way, 512MB is the bare minimum to run FCE, you will find things much better overall if you upgrade to at least 1GB.

How do I change the audio sample rate from 48kHz to 44.1kHz for Mpeg2

Hey all,
I've been searching for a while but haven't found any direct answers in the forums or the user manual so here goes.
I have to dispatch a file to Bloomberg TV and the file specs they have given me are as follows:
Video Standard: MPEG-2, MP:ML, 4:2:0
Frame Rate: PAL 25fps
Video Size 720 x 405
Aspect Ratio 16:9
Audio Standard MPEG-1 Layer 2
MPEG-2 Program Stream Mux rate 6mbs per second
Bit Rate Type: CBR
Video Bit Rate 5.7mbs
Audio Bit Rate 192kbs
Audio Sample Rate 44.1Khz
Interlacing: Upper Field first (why they want interlaced for web streaming is beyond me)
GOP Structure: IBBP
I-Frame distance 12
Now everything above is fine except the audio encoding because even though I have set up a new setting from scratch I cant find anywhere to adjust the audio sample rate. The Inspector tells me the Audio encoder is set to:
Format: MPEG
Sample Rate: 48.000kHz
Channels: 2
Bits Per Sample: 16
Anyone Know how or even if I can change these audio settings? The only adjustments I can find are the filters or the transport/program stream option. I have it set to program as specified by Bloomberg.
Thanks in advance
J

The only setting that I could find in compressor that lets your change the bitrate to 44.1 is when you create a new dolby digital setting and then under the inspectors audio tab/Target System button, change the button to Generic AC-3. When done, you can change the Sample Rate to 44.1.
Hope this helps?

How is Core Audio sample rate set?

When I play a particular movie in QuickTime, the audio and video are out of sync. The movie plays fine on other computers.
This Mac Pro (OS 10.6.8) is used exclusively for Pro Tools and Final Cut Pro. The audio hardware is a Pro Tools HD Native card:
Native card --> Pro Tools Digital I/O boxes --> Lavry D/A converters --> monitors
The sample rate of the Digital I/O boxes is set by an external master clock, a Lavry Gold A/D converter.
I opened the DigiDesign Core Audio Manager and it says:
Connected @ 44.1K, 32 In/32 Out, Buffer Size 512
Yet the movie is at 48K (I know because I created it in Final Cut Pro), and the external clock is set at 48K. So, I don't know where the 41K in the Digidesign Core Audio Manager came from. This is why I am guessing the problem is sample rate.
Please help me understand what sets the sample rate.
Does the application using Core Audio set it?
If so, how is this made consistent with the sample rate set for the hardware by the external master clock?
Do I have to be sure I always change the external clock setting to be consistent with the movie being played?
BTW, I have not had a sync problem when I play video in Final Cut Pro..........it is always in sync. So, I have never worried about how Core Audio works. The sync problem is only with QuickTime.

You might ask on the GarageBand, Logic or Final Cut forums. There is not much audio traffic here.

How do you set sequence audio sample rate?

I tried posting this to another, but it was already answered, and noone will see it.
I am getting the capture error "audio sample rate doesn't match" and yes, I can see in my browser that the clip is 48khz/16bit, but the sequence is 48khz/32 bit. Howver, wherever I look to change the sequence setting, it is 48/16 already. I've gone to FCP on the menu dropdown to audio/video settings - it's correct all through there. I've gone to the menu dropdown Sequence settings, and it's correct there. I've closed down, opened a new sequence, restarted, everything I can think of. Is there a secret to getting them to match? And, can I fix a project already edited with this discrepancy? Its export to QT is WAY out of synch.

Annoying - I can't see your post when I am in reply mode.
Yes, I get this error when i am capturing. From reading a previous post about the error, I thought the solution was to check the audio rate of the captured clip in the browser, and then make sure it matched the audio rate of the sequence. Like I said, everywhere you get to change the sequence setting, it SAYS it is 48/16, but yet, whe I scroll over in the browser, it says the audio rate is 48 KHz and the audio format is 32-bit floating point. Am I looking at the right places?
I can't check the settings in the camera until this evening...don't ask.
I'm not so sure this is not a QT issue instead of anything to do with capturing, etc. It plays back fine in the timeline.

Mismatching Audio Sample Rates Upon Capture

I recently bought a cheap MiniDv JVC video camera, and I am having trouble capturing video and audio together in FCP 6.0. The capture seems fine, but when I finish an error pops up which reads: "The Audio Sample rate in your presets does not match the one on your source tape." As a result there is a delay between the video and audio tracks that creates huge amounts of extra work.
My video camera captures sound in 12-bit format, and from what I understand that usually corresponds to a 32MHz sample rate. I can't find any 32 MHz presets in the Easy Set Ups or other menus, the system seems geared entirely towards 48 MHz sound. I've messed around with some different combinations of settings, but so far to no avail. Any help someone can give me will be much appreciated.

You might want to duplicate the capture preset for DV/NTSC 48k and change the audio to 32k.
Then try that.
But I'd also change the JVC's audio settings to record in 48 while you're waiting. Should be able to do it... cheap or not.

Problems with audio sample rate when capturing DV50

Hello from Spain, I have a problem when capturing DV50 source footage: I setup my sequence settings and capturing settings like always, DV50 codec and 48k sample rate for audio, then when the capturing process finish the result is a file that contains audio to a non-48k audio sample rate, then video and audio don´t match. The sample rate is 47945 and other similars, not always the same, sometimes 47214 sometimes 48000, and there is no rules...My capturing device works ok in other computers and the footage has been capture ok in other Mac...I don´t know what happens.
Sebas, kind regards
G5 Quad Mac OS X (10.4.6)

Hello!, first of all thanks for your reply. Yes, the camera is the same, the problem is on my computer, I have discovered a solution: first I capture the audio, only the audio, and then the video, only the video. After this I soncronize the two separate files on Final Cut timeline. It´s a slow process, but I am really desesperated. I don´t know what happens, I few minutes ago I have captured a 30 mins. video and the sample rate of the audio was 42.145k (???). It´s a crazy thing...

How do I capture at an audio sample rate of 44.1 KHz?
