So, you want to be able to export or extract audio from video on Mac and/or iMovie. If you are using iMovie 10.0 as part of the OS X Mavericks, you probably ran into the same problem I did. Unfortunately, it appears that there is no way to do it like you could in previous versions of iMovie.
You can achieve the same result by watching the video or by following the steps below.
How To Extract Audio From Video on Mac:
- “Share” (i.e. Export) your iMovie project as a File.
- After your video file is done rendering, go to where you saved it.
- Right Click, and select “Encode Selected Video Files”.
- Next to “Setting:”, select “Audio Only” from the drop-down menu, then “Continue”.
- Your audio file should should appear after a few seconds as an .m4a file.
From here, go ahead an play your file to hear that all of the audio from the video/iMovie project has been carried over. Now you are free to import the .m4a file into Logic or Garageband to edit the audio or do whatever else you need with it.
