Audio Studdering problem in FCP

I'm using Final Cut Pro 5.0.3 on OSX 10.4.3.
I've been testing building slideshows today and through the whole process I've had problems with the audio studdering right at the beginning and at intervals in the track.
I've tried exporting via compressor and directly exporting to aiff, both have the problem. I've also had FCP to render the audio and when i start playback, I have the same problem.
The audio track contains several MP3 files that when played normally sound perfect, so there should be no reason it would be doing this.
Anyone have any ideas, I'm going to have to do a wedding slideshow soon and at this point I cannot get anything to build that works.
thanks,
mike

Just to add to Phunam's correct answer:
#5 Imported music from CD or iTunes
Shane's Stock Answer #5:
To get music into FCP, it needs to be an AIFF file at 48khz, 16 bit stereo. So if you want a song from a CD, you go into the iTunes Preferences and set this up under the IMPORTING tab:
File > preferences > importing > import using - AIFF encoder > Setting - Custom
Sample Rate - 48.000 kHz
Sample size - 16 bit
Channels - Stereo
If you have an mp3 that you want to use, then you can convert it thru iTunes as well.
If the piece of music you want to use is something you purchased thru iTunes, I'm afraid I can't help you there. There are copywrite issues that prevent files from being converted into the format that FCP can recognize.

  • Audio exporting problems: from FCP to protool/STP and back again

    Final Cut Pro sound export for mastering.....sync problem
    Hey,
    I'm editing a 30 minute film and I have done most of the sound edit in FCP and Soundtrack pro and I want to now bring all the sound into pro tools to master the sound but every time i export sound into pro tools it seems to stretch by two or three seconds.
    I have tried OMF, AIFF, XML, and Quicktime audio file sut to no avail!!!!
    There are 50 tracks in the file so it is quiet large. It's not that there are handles of the file also as when I sync the file with the audio track with the video it syncs in one place but it is still out of sync in another.........It's as if the audio has been stretched!?!
    If anyone has any advice it'd be much appreciated
    Keith

    Check the timecode rate and sync options in Protools. It sounds like a timecode or samplerate mismatch.
    Especially note that 23.976fps OMFs from FCP (probably STP as well) show up in Protools as 24fps sessions. Change the PTs timecode to 23.976 to realign.

  • Audio sync problems withs FCP/Shake

    When I reconnect offline mediafiles in FCP after keying in Shake my audiotrack is out of sync. What is the reason for this and how can I avoid it?

    I think I found out.. I have to render i FCP to get audiosync again.. Even though FCP says it will play fine without rendering..

  • Problem sending FCP X audio output over USB connection

    I have an Antelope Eclipse digital audio converter/monitor controller. It connects to my Mac Pro via USB.
    I can play audio just fine out of Pro Tools HD Native at any sample rate.
    However, I have just discovered that the audio from FCP X is distorted and "wobbly"......apparently there is a sample rate sync problem between FCP X and the Eclipse.
    The audio in question is Linear PCM @ 48kHz.
    Is there a problem with FCP X sending audio out through a USB 2.0 connection?
    Do I need to change some FCP X settings?

    Thanks for the input. Yes, I am aware of possible latency issues. I would stay with low latency sound cards like the Pro Tools card, which worked fine. There would be no D/A conversion, so latency is usually not an issue.
    I have asked about compatibility with sound cards in a separate thread, just to be sure any sound card that the Mac Pro recognizes will work:

  • FCP:  AUDIO SYNC PROBLEM

    i have audio sync problem -- of the finished product which didn't have that problem before. does anyone know how this could have happened? in my earlier posting, there was a warning window which i played around w/ and now i have an audio sync problem in my prior projects.
    please help me.

    The Reels, are indeed the 5 surround channels. I have a feature that is broken up into 8-10 minute sections. I did this because the composer was using a G3 at the time and couldn't handle the whole movie at once. They are 16bit 48khz aif files exported from ProTools. The biggest thing here, is that at one point everything was in sync. I am trashing the preference files now to see how that works.
    It's not a playback issue as well. When i scrub one frame at a time, the sync has drifted off later in the clip. It's very strange.
    In my previous post I said the one of the Reels was in sync. That was because I recreated it, by making a new project and copying the video from the timeline, and re-importing the 5 audio streams. It didn't work for any other reels though. it is still out of sync in the main project.
    Trashing prefs did not work.
    Also, I tried a lot of the things in that technical doc, but non of them worked including trashing prefs.
    The real weird part is that the Audio file SAYS it is the same length of the video, but the audio ends later. It's in sync in the beginning but not at the end.

  • Audio sync problem downloading VHS-C

    I've downloaded a straight VHS tape (with no audio sync problems) into final cut pro once I had changed the Camera setting to 32Khz and the capture and sequeence presets to 32khz as well (it was all aout of sync when the settings were 48Khz).
    The problem now, which is driving me MAD, is I have 13 hours of VHS-C tapes, which I have put into a VHS cassette converter to download and the audio is out of sync. The capture presets are the same as above (i.e. 32KHZ) . Why is this? I downloaded them initially at 48Khz (settings on the camera 48Khz and FCP at 48Khz in capture and sequence settings), but this was also out of sync.
    Why is it different from one VHS tape to a VHS-C tape?
    I hope there is a God out there that can help with this one?
    Thanks!

    Eagleray:
    I capture through a ADVC-100.
    I use to find the same problem playing VHS tapes with a standard VHS player from time to time and never solved it. The out of sync audio appears when capturing some specific tapes from specific sources:
    - All my home tapes recorded in my old VHS recorder shows a audio problem; not specifically out of sync, but some audio "cracks" from time to time, like an electronic noise. No way to find a capture setings that works.
    - Some customers VHS tapes that showed the out of sync (no noises) and again, no combination of digitalizer settings made it works. Had to resync the audio editing and stretching in an external audio editor or cutting shorts parts and syncing them with video. The our of sync appears in small captured portions, like 10 min or so.
    - Never found a sync or audio problem capturing from VHC-C (the small VHS tapes) playing them with the tape adapter in the player.
    I google long hours about this problems and all that I learned is that some old VHS recorders had not a "synchro" signal in the tape.
    As I told you, I don't use any pro VHS deck, just my consumer "state of the art" VHS home recorder.
    I hope there is a God out there that can help with this one?

  • Audio synch problem

    I have a 1 1/2 hr program in HDV that I'm having audio synch problems with during export. All my frame rates for my clips are the same as well as my audio sampling rates. It will start fine, then be slightly off and by the end of the program that audio is behind by about 3 seconds. I've tried all formats, reference file, self-contained, Anamorphic DV and still no luck. Any ideas?

  • I have problem in FCP while playback in Sony TV, it only shows freedge frame, Video can play smoothly in FCP but in TV it shows only Freedge frame.

    i have problem in FCP while playback in Sony TV, it only shows freedge frame, Video can play smoothly in FCP but in TV it shows only Freedge frame.

    Come on gents and gentesses...... I'm really sweating on this one. Can't properly display my combined audio and pic when showing the Timeline contents of FCP in the MacPr's TV monitor Only the pic is appearing without any proper sound, as reported above. Just a mono row.
    Does nobody have any idea on the problem or am I too far up to date with the MacPro and FCP 5.1.4 for even Apple to let me in on the way to rectilfy. Bloomin' upgrades...... !

  • Audio Render and New FCP Versions

    An odd, annoying, time-consuming problem which I hope somebody can help with...
    A client has brought some audio files mixed in FCP to me for mastering. She has FCP 5.0.?, I have 6.0.4 on my Mac Pro and 5.1.4 on a G4 Quicksilver.
    On opening some of the aif stereo mixes that my client had exported, we found numerous clicks and pops that needed fixing (par for the course, it seems, when getting "creative" with sound in FCP?). In addition, much of her audio seemed randomly in mono.
    We opened her original FCP projects and, again, much of the audio was in mono. We quit, deleted render files and restarted - now we had the stereo back. For some reason her system was rendering in mono.
    But now there was another problem. She's been very creative with the "speed" setting on imported sound clips, but the pitches were frequently wrong. For instance, a sound she had set to "Speed 35%" was now at 9%.
    We opened the project on the G4, hoping that as the FCP version was closer to hers, we'd be safe. Now, the same clips no longer referenced the same bits of the original audio files, leading to incorrect sound or silence. And the "speed" was now set to "variable". We spent a few hours trying to sort this out - in the end she has gone home to try to sort it out on her own rig before coming back to me.
    Is this kind of thing common - audio settings such as "speed" corrupting when opening projects in later versions of FCP, or file references scrambling? Or am I getting something very basic, very wrong?
    (btw - we always worked on copies of the FCP projects, so she still has her originals to work with).
    Is there any particular settings I should be using, or workaround to avoid this?
    Thanks!
    Mark.

    Here's a couple of answers. I don't see any difference between what I sent to STP and what I got back as far as Vid Rate (23.98), Frame Size (1440x1080) or Aspect (HD 1440x1080). Where I do see differences is in the number of tracks (4V,10A for original and 4V,8A in what comes back - I cleaned up the music track in STP and made it one music track). Also I noticed Audio Output went from 2 to 6. But, where I'm seeing the need to render is on the video track. When I import the video, I am using the HDV - 1080p24 preset.
    As to what is in this video: some 108024p video, lots of images, text and title blocks, VO, music, and the associated audio track for the standups and b-roll.
    Thanks,

  • Smaple rate problem with FCP 7

    Hi!
    I have a problem with the sample rate on FCP 7
    After the capture comes this 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.
    My vide playback preset is Apple FireWirePal and the audio Firewire DV
    What can I do for this?

    If you look in your camera menus I am certain there is a way to turn on the display that shows the sample rate of your audio. It will say either 12-bit or 16-bit. 12-bit on the camera is 32k, 16-bit is 48k.
    As Michael says, if it's not drifting out of sync you don't have a problem in FCP. The only thing is you may have a problem with the camera not recording correctly, which may cause other problems.

  • QT 7, audio studders.

    I had QT 6 Pro with zero errors.
    Now I installed 7 Pro and my audio studders in the player and on web based video.
    Any ideas?

    New to QuickTime 7 is the option for various audio output formats. Surround sound (5:1 and even 7:1 or higher). Higher Hz outputs and sample rates and frequency settings to boot.
    On the Mac platform we have a software tool (Audio MIDI setup) that allows us to configure these various settings.
    I'm sure, that if you looked at your sound card output formats, you could fix your problems.
    BTW, the word is spelled "stuttering".

  • TS1363 Audio Sync problem - Audio is late, after a scene people are talking and audio does not relates

    All the TV shows purchased and downloaded have AUDIO SYNC problem.  This does not happens with any other video I watch from other sites, i.e. ABC, NBC, Showtime, all which I watch with no audio problem.
    The audio is always late, people are talking and scenes change and the audio belongs to the past!  Please help me to solve this!

    hi vcp
    welcome to the forum, glad you made the switch ... you won't be sorry (although you might be wondering at the moment!)
    1. nothing wring with that
    2. no
    3. just don't install 3rd party crap you don't need ... and don't install any anti-vrus software
    4. no special settings required
    what camera did you capture from? did you capture with FCP?
    cheers

  • Problems with FCP 5.1.4 and OSX 10.4.9

    I upgraded to Tiger, installed the new FCP Studio and everything was working fantastic.
    The next morning there was a software update for Tiger and FCP-5.1.4, it's been a nightmare ever since. When I restarted FCP would not recognize my Sony HDR FX1.
    I had this problem once before with 4.5 and I fixed it by re-installing FCP and doing the upgrades, so that's what I did with 5 but this time there was a new problem. It wouldn't let me work on anything that I had opened since I did the software update, so I had to do the update again and then FCP wouldn't recognize my camcorder again on startup. If you pressed log and capture you could control the camera but no capture was possible.
    So I re-set the easy set-up and presto! everything was fine and I worked productively for a few days.
    But then I had to capture some SD from my Canon GL2 so I reset all the settings for DV NTSC and reset the easy set-up for DV NTSC but now FCP won't recognize my GL2 on start-up. If I click log and capture I can control the camera but no capture.
    My next try to solve my problem was to downgrade back to my original 10.4.6 and FCP 5.1
    That put be back to square one and everything works fine again except I am left with the problem that everything that I worked on after I did the update won't open, I get error 41.
    Now I know this is because I am now trying to work on these projects with 5.1 after they were worked on in 5.1.4. But the problem is that everytime I update to 5.1.4 I can no longer capture or print to tape.
    I tried the trashing the FCP prefs thing and the repairing permissions thing but I can't seem to solve the problem.
    Has anyone else had any problems using FCP 5.1.4 and OSX 10.4.9?

    Not sure how you tried to install 10.4.8 but if all
    else fails you can always reinstall the original
    operating system that came with your Mac using 'Erase
    and Install' then upgrade it to 10.4.8 - probably in
    stages.
    Erase and install should be used as a last resort! A better option is to use the "archive and install" feature. It renames your old system folder and creates a new one for the OS you just re-installed. That way you don't have to reinstall everything, your user accounts and emails should all still be there, and if something doesn't work, you have your old system folder to pull things like preference files out of.
