Hi guys
I've got an mp4 file that I'm trying to split the audio and video of using iMovie. I've split the audio and video tracks, and deleted the video, but when I export the file as an mp3 (other formats have failed too) the audio only plays back up to a point, after which the rest of the file is silent. I can hear all the audio in iMovie, but not in the exported audio file.
MacBook Pro 15″, macOS 10.15
Thanks Rich! I've tried deleting preferences, creating a new project, and choosing other audio formats, but no luck. I did however manage to find the below linked workaround - which is actually easier than using iMovie - so I'm sorted now:

Thanks again for your quick responses.
Mp3 audio files can sometimes be problematic.
Try exporting the project as an Audio Only file (an option in the export box) and choose AAC audio codec as the format. See if that works. You can also choose aiff audio format.

I just noticed from your original post that other audio formats than mp3 have failed as well. There may be something amiss with the rendering process when the audio is shared out. So, if the procedure I suggested in my previous post does not work, 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. Deleting preferences is a safe procedure that will not cause data loss or disruption to your project. It sometimes cures rendering issues.
Another thing that you can try is to transfer your media to a newly created project and share out from there. That would be to rule out some glitch that is confined to your original project.

Great! Glad you got it working.

iMovie exporting - audio cuts off
