The standard Animoto website allows you to make 30 second videos for free with about 12 items (photos or video clips). Add text over slides and spotlight the special slides. Add music by choosing tracks available from the Animoto library or upload from your own computer. Once the movie is generated it can be uploaded to Facebook, Twitter, or any social networking site, and it can be embedded in blogs and wikis.
Animoto for Educators allows more choices. Click on the Apply button to lodge an application for Animoto for Educators. Create longer videos and export to Youtube or download to your own computer.
