Activity Forums Apple Final Cut Pro Legacy waveform do not match the actual audio sound

  • waveform do not match the actual audio sound

    Posted by Andrei Bocharnikov on December 16, 2009 at 10:06 pm

    Hi guys,

    again problem with FCP 🙁

    Cannot edit audio on timeline because waveform image do not match the actual audio sound of the track. First i did editing just visually according the image of the waveform but in the middle of cutting the sound i noticed that i cut out the beginning of the sentences. then I scrubbed the sound with the mouse and found out that waveform cheating me. At the beginning of the track everything is ok but as timeline progress the delay of sound and waveform is bigger and bigger. at the end i can not even find the sentence picture of what i see on timeline. It is really horrible.

    I went through search of the forum and found some similar posts. I was trying to trash all waveform cache files, did mix-down of the sequence and deleted all the audio renders from render manager but problem is exactly the same in spite of all my try.

    This problem is only with new files i import to project. all audios are perfectly matching waveform image and actual sound behind it. Also i was trying to cut it on Macbook Pro and the same file has perfect waveform image on timeline.

    Also the problem is only on timeline. WHen I open the file in viewer then waveform there is also perfect without any delay along the whole file from the beginning to the end.

    I am freaking out… deadline is very close but i can not re cut new narration.

    any tips and suggestions are really appreciated

    Thank you guys for the response! Both these things I did at the beginning of the problem as first (as i mentioned in my original post). Nothing helps.

    Hi
    Extremely loud LOL!
    I live with this daily with FCP 5.1.4 – if a linked (synced) shot is edited with the audio slipped out of alignment the Viewer waveforms are kaput…

    Every day I think that once I upgrade to a more recent version of FCP it won’t be so.
    Tell me, Please!!!!

    [Paul Dickin] “Every day I think that once I upgrade to a more recent version of FCP it won’t be so. “

    Paul, I own FCP 7.0.1 (latest) … I suffer from this problem and can not find the solution.

    Going to backup whole project and do clean reinstall of the OS plus FCS3. Let us see if this will help…

    Dave, I did it as soon I noticed the problem. No success…

    Andrei, I had this problem recently and was able to fix it, but I don’t know if the situation is the same as yours so my solution may not apply.
    I had converted some low res quicktimes (23.98 h264) to dv codec for a quick and dirty temp edit. When I dropped the movies into a timeline, the waveforms had the same problem. I realized that QuickTime was not setting the framerate properly when I converted the files and fcp thought they were 24.00 fps. I also noticed the orange “effects” bar on the audio tracks (this is what tipped me off something was wrong). Anyway, I converted the movies again, using compressor this time and the problem went away.
    So I don’t know if this helps, but maybe there is an inconsistency in your media’s frame rate and your sequence setting…. A long shot but I hope this helps…

    Matt thank you very much for your detailed input. My audio is not from video but it is pure audio recorded in studio by voiceover artist. Then it was processed by our sound technicians and now i have it as it is. No video associated to the files at all. So, i do not think any fps things is involved in my case.

    i will check the orange marks you mentioned.

    thank you again

    no problem Andrei, happy to help. I actually think that more can go wrong when dealing with just “pure” audio files. Select your clip and hit command-nine to open the “item properties” window. Check the audio format, sample rate and bit depth and compare them to your sequence settings. As a test, you might want to re-convert a file quickly in Quicktime player to AIFF and see if the new file has the same problems. Use whatever bit depth and sample rate settings match your timeline.

    Andrei, I looked through all these posts and did not see any reference to the actual format, sample rate and bit depth of the problematic files. Can you provide this info? Sorry if I missed it.

    Cheers,

    I had a similarly freaky sound problem in FCP the other day. It involved sound drifting out of sync and waveforms not matching actual sound.

    Although the symptom description doesn’t cover the waveform poblem this helped:

    https://support.apple.com/kb/TS1256

    Symptoms
    Imported audio-only files in a sequence with PAL video may drift out of sync in some cases.

    Products Affected
    Final Cut Pro
    Resolution
    If this occurs, try the following steps to resolve the issue:

    Delete the audio file(s) from your sequence in the Timeline and also from the Browser.
    Choose Final Cut Pro > Easy Setup.
    Choose PAL from the Format pop-up menu.
    Choose a frame rate (usually 25.00 fps) from the Rate pop-up menu, and a media format that matches your source video from the Use pop-up menu.
    Click Setup.
    Choose File > Save Project.
    Choose Final Cut Pro > Quit Final Cut Pro.
    Open Final Cut Pro and your project again, and re-import the audio file(s).
    Edit the audio back into the Timeline.
    The audio should now stay in tight sync respective to the video in the Timeline.

    Additional Information
    This issue can arise if you import audio files while the default sequence setting is an NTSC-related frame rate (such as 29.97, 59.94 and 23.98). Setting the preset to a PAL rate and restarting Final Cut Pro should allow newly-imported audio files to conform to PAL timing.
