Hi, can someone tell me how to get rid of the scrolling vertical black lines that move across my images in iMovie in a project?

I have completed a project in iMovie and when I play the completed piece there are vertical black lines scrolling across the images as the film plays??? How can I get rid of these?

MacBook Air 13″, macOS 10.13

Hi,


Try deleting 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.
