  Audio cutting off when layered????

  Posted by Alan Langdon on April 1, 2006 at 11:48 pm

  Mac OS X 1.4.5
  G5 1.6 MHZ 1 GB RAM
  FCP HD

  I am having a problem which has happened a lot with me: I have a timeline with multiple audio tracks, each with audio coming from different AIF files, audio from MiniDV tapes, etc… And certain layers will clip off, cut off when I create a master Quicktime file (FCP video file) or sometimes even when I playback the timeline… It’s not a volume issue, as I am not clipping. Could this be the white (mulinance) getting too high and clipping the audio? sometimes the entire audio from the final FCP mstare file is mute for seconds, no waveform either.
  I never had anything like this in FCP3…

  Any help will be much appreciated!

  There is a function in FCP that is often overlooked… and it can help with many audio and video “skipping”, “sticking” and “missing” problems.

  You should “Mixdown” the Audio for playback before you dub out of FCP, or during the edit, if you have audio/video stuttering, drop-outs, sync-slippage, or freezes.

  NOTE: Mixdown has even been demonstrated to help with slipping, skipping problems (or “missing” audio clips) for files being EXPORTED as QT (or similar) files out of FCP.

  First, SELECT ALL of your audio tracks (highlight them) on the timeline, then:

  Sequence Menu > Render Only > Mixdown.

  You should see a dialog box telling you its rendering.

  It might seem to make little sense that “Mixing down” even simple audio tracks will “fix” complex video “freezes” or random audio dropouts to tape or export, but it CAN.

  NOTE: It does not matter of you only have one audio track, if there are random freezes during output, you should try the Mixdown.

  Many Thanks! I will try this… I temporarily solved the issue by exporting the audio as 48 KHZ AIF and then pasting it into the timeline… Did I do something wrong? Will I use quality? I assume not…

  Thanks! The mixdown function shall help me tons, I am sure!

  No, the quality will be fine.

  But if the mixdown works, it will be much easier and faster to accomplish.
  Plus, your timeline will still show all the tracks exactly the way they are laid-out and edited, so you can still make changes.
