The Open Video Project
http://www.open-video.org/

With the increasing demand for digital videos in the educational and research communities, the Open Video Project aims to provide an easy to-use open source DV archive, while serving as a testbed for digital library research and development at the Interaction Design Laboratory. Currently the collection contains about 2,000 individual segments, in MPEG-1, MPEG-2, MPEG-4 and QuickTime formats, contributed by government agencies, universities and individual collectors. Most of the 460 hours of video footage have been edited into shorter segments for faster downloading, and include metadata at three levels: entire video, segment and frame. Various kinds of video representations, known as surrogates, have also been created, to speed the process of selecting the desired clip. Surrogates range from a single thumbnail image to a storyboard displaying multiple key frames simultaneously, as well as slide show and fast-forward types. There are also traditional text surrogates like title, keywords and descriptions. Each surrogate category is being evaluated to see how much people could understand from watching only these surrogates, as well as how they interacted with textual and visual information. In the second phase, surrogates have been integrated to create 'Agile View' interfaces for users to explore video content.
