IMovie

iMovie ’08 makes viewing and working with video as intuitive as enjoying your photos. A built-in library automatically organizes your video, so all the clips you’ve captured and movies you’ve created are just a click away. With its revolutionary interface, iMovie makes it quick and easy to browse your library and create new movies. And iMovie is built for sharing. In just a few steps, you can add movies to your website, publish them on YouTube, and create versions for iPod, iPhone, and Apple TV. (source:'http://www.apple.com/ilife/imovie/)
