Audio Delay In Timeline

Hello Everyone
It's me again still having audio problems. The next problem is there's a audio delay in the timeline, someone is speaking and I can see the video and audio not in sync.
How can I fix this problem?
Thank yoy
Sabrina

First, how are you viewing this? You need to view on an external NTSC monitor or TV at the very least. Viewing on your computer screen may not be accurate.
Is the delay consistent over time, or does audio drift further out of sync over time?
Do you see a red number at the top left of a clip, next to the clip name? If so, control-click on the red number and correct the sync there.
If no red number, it could be something else. What tape format? How was it captured?

Audio delay in exported movie. Help!

I have hdv video that I captured in premiere. Watching the imported video, there is no problem. But when I try try to export the movie to anything, there is a significant delay in the audio. Windows movie maker actually can read the original and when exported, the movie maker file audio matches the video (although movie maker does not maintain the proper aspect ratio).
Am I missing a setting somewhere?
Thanks

Sorry.
Premiere Pro CS3
Alienware MJ12
3GB Ram, 2 HDD
Video originally recorded on Canon XH-A1
Video captured in premiere from Sony HVR-M15U
Video is NTSC 1080i 60
Project settings are HDV 1080i
original and exported video go to default my documents folder
I just import the mpeg2 file into the composition, drag it onto the timeline and then try to export it. I've tried exporting to different formats and with different settings, but always have the same audio delay. The original mpeg2 file plays fine in media player.
Thanks

Quicktime video recording - audio delay

If i try to record a video using quicktime and my built-in webcam, and have the audio volume turned up so i can monitor as i record, there is a delay.
This is the only program that delays audio as i record. To be clear, the final video is not out of sync, its just the audio delays if i try to listen as i record (important if you are recording guitar like i do)
Any way to make it not delay?

JTBluesmaker, When you record the computer has to capture the video/audio and then convert the video/audio and then play it back. I believe Quicktime is monitoring the recoding and not the audio input. With that, I would say there going to be a slight delay.
If you have something like Apple's GarageBand you should be able to monitor the audio input.

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.

Emulator on OSX don't support capturing audio, is this a BUG?? SDK 3.0

Hello all,
well i'm trying to capture audio with the emulator on OSX. When i test the System Properties for capturing audio i always get FALSE.
I tried the same application on Windows XP with the SDK 3.0 and it works, i'm getting True and can capture the audio with my microphone.
Now i want to know if this is only a Bug and could be fixed or is the support for capturing audio on Mac OSX not implemented yet?
Thanks

Capture Audio and Video to different disks or not?

I thought that capturing audio and video to separate disks was more efficient, now I see in the FCS 2 documentation it says that this is not recommended for any of the DV formats. But it does not say why, or what the consequences of doing this are...
Does anyone out there know?
Thanks,
Pete d.

Now, Is there any value in putting the render files on a drive that is separate from the Capture disks?
Pete D.
Absolutely. Listen to your drives while doing an intense render. The Capture drive is grabbing all of the video clips in the stack, the system drive is grabbing software. If you render to the Capture drive, that same drive has to write, too. Reduce the load by using a Render drive.
I have four drives: System, Capture, Render, Output. The last is used for all exports, encodes, and transcodes.

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.

Audio/video out of sync (audio delay) with PowerBeats wireless earphones.

I am having a problem with audio/video sync between my PowerBeats Wireless earphones with my MacPro and MacBookPro. I have tried pairing, playing the video, pausing the video, turning off the PowerBeats, tuning the PowerBeats on, then starting the video playback again. I have the same audio delay so this not working for me. Anyone have an update as to how to fix this audio/video sync problem?

I am playing MPEG-4 movie files. I did open MPlayerX from my dock, then pulled down File to select Open which then did show the folder where these movie files are stored. Then I was able to select a movie file, open it, and use "Decrease Audio Delay" to closely sync the audio with the video. I say closely because it is not perfect. Rather than stepping each increase or decrease in one tenth of a second, perhaps a finer adjustment would have been in milliseconds. This is the adjustment that I have with my AVR to sync the audio with the video, so I know this is a possible increment adjustment. The perfect adjustment was in between -0.4 and -0.5 second,however, this was not possible in one tenth second adjustments. The closest adjustment was with -0.4 second rather than with -0.5 second. So, adjustments in milliseconds could have been very near a perfect sync. Perhaps later versions of MPlayer will offer the adjustment selection in milliseconds. Nevertheless, this is working much, much better than before. Thank you so much. I have spent most of this day researching this problem and you have come up with by far the best solution. This problem goes all the way back to 2010 and possibly beyond for Apple products. There are hundreds of reports documenting out of sync audio/video issues with no solution that works as well as MPlayerX. Even the Beats support staff have no idea of how to resolve the audio/video out of sync.

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.

Capture audio and video files to seperate files

Forum,
Having suffered problems with OS 10.5 and Quicktime 7.4.1 I have done a clean install with 10. 4 .11.
When I select capture the following notice appears
"Audio only capture selected,video preview disabled"
In system settings "capture audio and video to seperate files " is NOT checked.
But that may not mean the same as the statement in in the capture window.
I have searched HELP and a book called" Optimizing your Final Cut Pro System" but can not find an answer.
Advice would be appreciated.
Thank you
Michael Craven

Hi,
Check this:
in Log & Capture window select Clip Settings tab and make sure video box is checked.

Is there a way to CAPTURE audio/video off the net then run it m.m. prsntn

I'm fairly new to the mac genre. In windows we had apps like Camtasia to
capture audio/video off the net. I was hoping something like that would
be avail for the mac and then once capture it how would I edit it and
include it in a presentation software; for example, keynote?
Is there added hardware req'd (?Capture board)? what would be a good software mac
compatible?

I'd like to capture audio and video for example sometimes just need to capture the
audio if some instruction is coming say over a quicktime or media player for my work.
Then sometimes I need to capture the audio and video when they ware actually showing me
charts and explaining them things like that.
is snap Z the way to go then for quality and fair pricing to get good results.
Do we have any resident applications already on the ilife variety that could be utilized for
something like this or is the only way to go through a 3rd party vendor?

Willy, the procdedure you describe works perfectly for AppleTV G1. In fact, I frequently play DTS music discs ripped to my iTunes library as Apple Lossless (ALAC) and synched to the ATV. What happens is that, as far as iTunes and the ATV are concerned, a conventional stereo 16/44 audio file is being played; however my reciever detects the DTS data stream, and instead of outputting static, it decodes the 5.1 channels correctly. This process parallels the way DTS discs were designed to be played back: a conventional CD player is connceted, via digital out, to a DTS-aware reciever/pre-amp and the two channels of static are recognized as 6 channels of DTS-encoded audio.
However this process will only work if the player (CD, ATV, PC, etc.) sends a "bit-perfect" 16 bit/44.1 khz data stream to the decoding device. In the case of ATV G2 and G3, as has been discussed elsewhere, the unit resmaples all audio - including 16/44 PCM (Redbook CD) - to 16/48. While this is not a big deal for conventional audio CDs, MP3s, and AAC files, it mangles the fragile DTS datastream and renders it undecodable. The resulting static that you hear is just like the static you would hear if you played a DTS CD on a non-DTS capable system.
Sadly, I'm not aware of any easy way around this. You could use a program like Foobar (and the DTS plugin) to convert your DTS CDs to 6-ch .wav or .flac file. From there you could transcode the file to AC-3 and then mux it into a video container that ATV supports. You may need add a dummy video track, for iTunes/AppleTV to be ok with the file, though I'm not sure. This may be a lot of work.
Sorry for the bad news. I wish that the iTunes/ATV ecosystem had better multi-channel audio support.
