    We need more info....

     

    Are you creating a file and sending to the render queue?

    if so, what are your settings when you put it in the render queue?

    have you set the audio settings in the render queue

    can you do an audio preview on the file in After Effect? (press the "." key)

    What is the source format of the stuff? Also, when you say you can hear the audio, is it clear or are there any disturbances? To what specific CoDec do you render? If you render uncompressed, it's well possible that the data rates are simply too high and the system can't keep up. It also is important, where you play the file. Have you tried alternate player software like WinAmp, VLC or VirtualDub even?

    Is your audio file an mp3 ? If yes, could you try to convert it to wav or aiff ?

     

    What if you try to render the audio only of your project. Does it work ?

     

    And most important of all, what format is your audio ? Is it audio from a separate file or embedded in your movie clip ?

    Avastjonny: It's very important that you provide more information, as the other forum members are requesting in order to help.

    What AE version are you using? What format is your audio? Is it a separate audio file or is it embeded in a video file?

    FWIW, in After Effects CS3 and later, MP3 audio is supported (it's actually converted to PCM, ie WAV/AIFF in import). In previous versions, yes, converting to AIFF/WAV would be a good idea? Other compressed formats, like AAC, could be a problem.

    Quick Question:

     

    if you import your exported AVI inside After Effects, if you expand the audio to show the waveform, is the waveform going through your whole file or does it stop after 3 seconds.

     

    And what codec are you using when you export to avi ? DV, indeo, divx ?

    AVI is not a codec actually, it's a file type. AVI files can have a numerous different codecs. So when you render, in the output module, when you clic on format option, what is the codec used ?

     

    My guess is you are exporting to uncompressed avi file, which are enormous and thus can barely be played in realtime on a non raid hdd.

     

    Because, if your exported avi, once reimported into AE have the whole waveform and you can preview it al along with sound, then it doesn't come from AE, but from your Media player.

    what if you export your audio alone in wav or aiff, and then reimport it into after effect, add it to your time line, disable the audio from your video file and export. DO you still have your audio cut out ?
