Answers.Text: I always forget which codecs are default and which I installed myself. To be able to export WAV (Waveform Audio Files) you will need [Flip4Mac](http://www.telestream.net/flip4mac-wmv/overview.htm). But you **dont** have to use WAV. You could just export it as a MP3 which would work just a well

Answers.Body: <p>Try to convert your video into ProRes422. I guess the video codec of your source material is using some sort of compression, that After Effects is having problems with and is loosing sync.</p>
  
  <p>On OSX ProRes422 comes with Quicktime or can be downloaded as a <a href="http://support.apple.com/downloads/Apple_ProRes_QuickTime_Decoder_1_0_for_Mac" rel="nofollow">free Update for Quicktime</a>.

Body: <p>Asked this question before... having same problem.</p>
  
  <p>When I go to the RAM preview of After Effects, the audio of the video will play on sync for a while, then will get screwy. Sometimes the audio will jump ahead or before it should. It is making the sound choppy and my characters sound stupid.</p>

  Sounds like After Effects is having a problems reading the audio from the file. I'd suggest converting the audio to a separate `.wav` or `.mp3` and importing it back into After Effects:
  
  > 1. Open **Adobe Media Encoder**
  > 2. Drag the file in question into the que
  > 3. Under Format select **Waveform Audio File**
  > 4. Leave the preset at its default
