imovie audio lost

I often lose the audio content when I import mp4 clips into iMovie. When I play the clips beforehand in QuickTime there's sound but when I import to iMovie (even doing one-file-at-a-time) sometimes the audio has disappeared. So I end up with a new project of, say, six clips, of which two are silent. Annoying . . .


Any ideas, please?


I'm running Catalina 10.15.7 and iMovie 10.2.1.


Thank you.

Hi, Trip35,


iMovie is a bit more sensitive to audio codecs than QuickTimePlayer. Try converting your troublesome clips to H.264, Mp4/AAC with the free download, Handbrake. Do that even if the codec already is indicated to be Mp4/AAC. Re-rendering often cures audio issues.


You can get Handbrake here:

A simple way to do it without fiddling with settings 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. Now see if you get audio.
