There's a lot more going on with iMovie ’11 than movie trailers and audio editing. In this TidBITS article, I reveal several tips, trivia, and otherwise unknown aspects of Apple's video editor: "15 Secrets of iMovie ’11".
Here are a couple of items to tease you:
Made with Morse -- Speaking of trailers, you can choose which studio logo appears at the front. In the Signals Across the Globe trailer, the music that plays in the background is actually Morse code for "Made with iMovie."
Change All Title or Transition Styles -- If you decide to change the style of an existing title, you can drop a new style onto the section of the clip the title occupies (the video clip turns bright blue to indicate you're affecting the title). Now, when you replace a title style, iMovie asks if you'd like to replace just the one title or all titles in the project. The same option applies to replacing transitions, too.
