Export Audio Alignment Issues

Hello,I’m currently working on a project and everytime I attempted to export the video file as a .mov, the video and audio alignment falls off track when previewing in the quicktime player. I made sure to shut down any other programs running to make sure they don’t interfere with the export. I have a quad-core computer with 16gigs of RAM. Thanks

Avoid using mp3 format audio in your project as this is a compressed audio format that can lose synch.If you are already using either .wav or .aif audio, try padding the beginning of the audio file with silence so that the track can begin at frame 1 of the timeline.
