Clicking on a button brings up a menu of things to put into your video. Everything is done automatically. If you want the transition to be faster or shorter, just move the length bar above the selections. Remember, you'll have to adjust it before dragging it to the time line. Once it's dropped in, there's no way to adjust it other than deleting it and redropping the transition.
Titles are a breeze.
Just choose from a variety of different titling schemes, select a font, color, and background, and type in your title. Note that even though the interface resembles QuickTime Player, iMovie cannot import QuickTime files. You'll have to export any QuickTime files into another format before iMovie will be able to read them. Now you can be savvy like Bob Saget and have those zany sound effects go off at key moments during your video. There's a wide assortment of sounds to choose from, and you can add sounds from your microphone as well.
