Why can't I detach audio in imovie?
I read the whole of this question thread from 2015 and none of the solutions worked so I am asking it again.
I uploaded a video file from a camera and detaching the audio worked fine.
I uploaded a second video file from my iPhone, and when I select the menu to 'detach audio', the command is greyed-out (inactive).
I tried adding a dummy audio track to the timeline as one of the posts in the above thread said you need to do this before iMovie will allow you to detach the audio, but it doesn't solve the problem.
The only thing I want to do is remove the audio from this video clip. That is all I am using iMovie for but after 20 minutes of trying I have not achieved this task.
I'm using iMovie 10.2.5 on OS X 10.15.7.
