Hi,
I have imported a video file into imovie 10 to trim the start and end and add 2 slides with audio.
It all plays fine until I export it, as half the audio on the original video is missing, it just stops.
Looking at the timeline the audio looks like it stops but when playing it in imovie you can hear it so I'm not sure whats going on?
Any help would be really appreciated. Thanks
So, as I understand it, when you play the clip in the timeline you can hear the sound as the playhead moves through the area where the wave forms are missing, but in the exported product the sound is silent through that area.
Try placing the video clip on your desktop and re-encoding it with the free download, Handbrake. That often cures audio problems.
You can get Handbrake here:
A simple way to do it is to open Handbrake and do a File/Open Source. Navigate to your video and choose it as the source from the resulting screen. Then do File/Start Encoding. Wait a couple of minutes for the conversion to complete. Then save and import the converted clip into iMovie. It should work fine.

Hi Rich,
Thank you so much for your reply.
I have tried this and it seems to have recovered slightly more of the audio than before but there still seems to be a section missing. I have attached a screen shot of the audio on the timeline for you. There is a section that looks like it doesn't have any audio but when playing it in imovie you can hear it. It is obviously missing though as when the file is exported you can't hear that section. I don't know why it is not picking it up. I have tried deleting and importing the original video file several times but when dragging the file down onto the timeline it seems to miss a chunk of audio?
Mel_W,
Try deleting preferences. To delete preferences Open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will open in a new library. Reopen your old library to get back to your projects. Now see if you can export and get the full audio.

Thank you Rich, re encoding the original video file worked! The video and audio both transferred fully to the timeline, I was able to crop and export and it played back perfectly. Thank you for your help with this.
You are very welcome. Glad you got it working. :)
