You have to be a registered user (registration is free) in order to download videos from Stockio. Update: you no longer have to register to download videos.

Applications for Education
I always recommend that students use their own pictures, sounds, and videos whenever possible. However, it is not always possible for students to use their own creations in multimedia projects. That's when I will have them turn their attention to a site like Stockio to search for images and video clips that they can download and use for free.
