I am hoping someone can help me. I have been using iMovie for ages and have never had any dramas until now. I have created a movie of my wedding and it plays perfectly until I export it. For some reason it then plays the audio from the end of the movie at the start!! I can not figure out why.
I have a lot of free space on my start up disc ect - 25gb. I have tried to re-create a new project and copy the details to the new project but the same thing happens.
I would recommend that for your slow motion clips, you stick to one of the pre-set values, like 25%, 25%, etc. This are the tic marks on the slow motion slider. If you use a custom percentage, like say 33% or 58%, it will mess up the sound.
