black bars
Well, i'm new to iMovie and wanted to make a movie, or rather edit a short move, made by iPhone.
I cropped the movie en exported. This came out great. Then I tried again but now black bars came in. This wasn't the first time, but i have no clue how i did it :-) Anyone here that can help me and tell me how i got that done?
