Audio sync when coverting imovie project to .mov file.
I have a project in imovie 09 that I have tried to convert to a .mov file but the audio is out of sync in a cople of place in the file. Infact having tried to share the file as a .mov file, the issue occurs in the same places each time. Playback of the projecct in imovie however is perfect. Can anyone help me resolve this?
