Browsing with dynamic key frame collages in Web-based entertainment video services

We discuss video browsing in the context of Web-based entertainment video services. We propose dynamic collages of key frames as a suitable technique for rapid evaluation of moderately-sized sets of candidate videos that have been selected via hierarchical browsing or querying techniques elsewhere in the interface. Dynamic key frame collages integrate temporal and spatial layout, and thus potentially retain the advantages of each. We relate our designs to the research of Marchionini (1998) and colleagues, who have evaluated the effectiveness of other temporal and spatial key frame presentation techniques
