Animoto is a web-based service that helps you create slideshows that looks more like videos. This is a web application that automatically generates professionally produced videos using their own patent-pending technology and high-end motion design. Each video is a fully customized orchestration of user-selected images and music. Produced on a widescreen format, Animoto videos have the visual energy of a music video and the emotional impact of a movie trailer. You can check them out with some example videos.
An Animoto Short is free but is limited to 30 seconds, whereas a full-length video is of an extended length with unlimited remixes. Just try it now!
