im currently creating a media project at AS level and have only had one major problem. Some of the film was filmed with one camera... another with another camera. One lot of the film was autmatically letterboxed by imovie not removing any footage from the top/bottom. The other was not automatically letterboxed. The change in size is glaringly obvious upon playback and simply adding a letterbox effect cuts off half my footage... how can i getthem the same? is it to do with aspect ratio?
