The online support says "constrain to HD" but when I do that, it just cuts off the top and bottom of photo - how do I resize it to keep the whole photo, just "shrink" it?
Double-click on the photo in the iMovie project to open its settings, and check if Ken Burns is selected. Turn it off and make sure the size slider is set all the way to the left. iMovie should display the entire photo with black bars at the sides.
