To best position yourself to assert a fair use argument when using video, consider doing the following:
The purpose of the Open Video Project is to collect and make available a repository of digitized video content for the digital video, multimedia retrieval, digital library, and other research communities. "The Open Video repository provides video clips from a variety of sources, especially various video programs obtained from U.S. government agencies such as the U.S. Records and Archives Administration and NASA. Although the government agency videos were produced with public funds and are freely available from the Archives, no copyright clearance has been obtained for audio or video elements in these productions. We encourage researchers to use the data under fair use for research purposes."
