iMovie producing Pink and Green screen

Hi, Tony,

The first thing to try is opening iMovie while holding down the Option and Command keys, and selecting 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. Then see if your photos display properly.

If that doesn't solve it, check to see whether the issue might be confined to just the current project. Instead of duplicating the project, do an Edit/Select All, Edit/Copy, of the media in the project and then Edit/Paste the media into a newly created project.

If still no luck, a procedure that has solved this type of issue for others has been to reduce the resolution of the photos. To do that, place the photo on your desktop and open it in the Preview app on your Mac. (It will do that by default when you click on the photo.) In the Preview menu select Tools/Adjust Size and in the box that appears reduce the long resolution number to a number less than 4000 -- go lower if you need to. So if, say, your photo is 4200 x 2000 lower the 4200 number to 3000 or whatever, and save the photo. Drag the adjusted photo into iMovie and see if it displays properly.

Also, iMovie likes the jpeg format, so check the format of your photos and change to jpeg if the format is something else, even if the photo already is jpeg. TIFF and png formats also will work.

You can try opening iMovie in a new library, and copy your project to that library, and see if that makes any difference.

You do that by opening iMovie while holding down the Option key and selecting to create a new library in the box that appears. iMovie will open in the new library.

All else failing you could try a reinstall of iMovie by moving the iMovie app icon from the Applications folder into the trash, but don't empty the trash. Then reinstall iMovie from the online app store. Don't touch the iMovie library itself, because if you delete the iMovie library you will lose your projects.
