Missing Transitions in iMovie
I edited a video last night on iMovie. I got up this morning and IT failed. When I went back to check to make sure there were not corrupt files/clip, I notices all of the transitions I had had a red and yellow X. I delete them all and went back to add them and now the transitions screen is completely blank. How would I get then back? Help please! I need this done by 6!
