American University has published a guide for fair use in making web videos. Their guide for best practices can be viewed here: Code of Best Practices in Fair Use for Online Video
With so many students and faculty involved in video media projects, this could be useful information for their work.
From an article by Jeff Young at The Chronicle: Wired Campus Blog on 7/8/08 "American U. Researchers Publish Guidelines for Fair Use in Web Videos:" "As more students and professors experiment with making short videos to post to YouTube or other video-sharing Web sites, many run up against concerns against potential copyright violations—especially if they want to use a clip from a Hollywood movie or other copyrighted work. New guidelines released this week by researchers at American University's Center for Social Media hope to help nonlawyers navigate the confusing world of U.S. copyright law and its "fair use" provision."
