I tried using this because iMovie crapped out on me while editing. The GUI is incredibly confusing and hard to use and the features it has that iMovie doesnt are cancelled out by the simply horrid and claustrophobic user interface. Dont waste your money, get iMovie instead. Da Vinci Resolve is also good if you have a computer, and its free.
