Yahoo! has just unveiled a video search beta available via a link on its Yahoo! Next site. The company is also introducing a new RSS-based video enclosure for producers to include with video content. Using the enclosure will help Yahoo (and others) discover and index media content. Much more about Media RSS, why Yahoo says it's needed, and some of the organizations Yahoo is working with here.
Video search is not a new concept, AltaVista (now part of Yahoo) has offered a video search tool for several years.
Yahoo Video Search leverages technology developed both internally and and via acquisition (AltaVista, Inktomi, etc).
Yahoo Video Search also offers an Advanced Interface:
+ Limit by format: AVI, MPEG, Quicktime, Windows, Media Real
+ Size (small, medium, large)
+ Duration (Less than or greater than one minute)
+ SafeSearch Filter
Note: The formats are the what's also available at AltaVista.
