iMovie thinks photos are audio files
When I try to drag and drop a photo I get the msg ‘You are combining audio and video clips outside the primary storyline’
Windows, Windows 10
HI,
Others have reported seeing that message. I don't know what causes it. You might try creating a new project and adding your photo first, before there can be any story line.
You might also try deleting/resetting preferences. To delete/reset preferences first close iMovie and then 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 empty library. Reopen your old library to get back to your projects. Possibly you may need to reboot to set the changes. Deleting preferences is a safe procedure that will not cause data loss or disruption to your project.
