Why can't I add transitions?!
I'm trying to work on a project, but iMovie won't let me add any transitions between clips. I can fade clips in and out, but nothing else. When I'm in the transitions pane I can highlight different transitions and it previews them perfectly fine, but the "update" and "add" buttons are grey and cannot be clicked. Any idea why? Thanks in advance...
