    MP4 video files have out of sync audio?

    EricIsMe

      When I import an MP4 video into Premiere Pro CS5.5, I noticed that while playing it the audio gradually becomes out of sync. I am unsure as to what causes this, but when I play the exact same video in an external player (like VLC) the audio is fine.

       

      I've tried using Audition to export the audio from the video as a WAV file, but upon importing that into PP CS5.5, I discovered that it becomes much worse.

       

      I'm not sure at this point if the audio is the issue or the video is the issue, but I'd really like an answer.

       

      Audio settings are at 48 kHz for the audio itself and the sequence in Premiere Pro.

       

      Thanks.
