Sorting video content using metadata -- the keyword tags manually attached to videos -- is like searching via an interpreter. Tags encapsulate one person's judgment of a video's content, and a tag-only search system will produce a lot of irrelevant results. "For video search to be really effective," says Mr. Chandratillake, chief executive of online video and audio search engine Blinkx, "you need better ways to understand what is going on in the actual footage". As well as metadata, Blinkx uses speech recognition algorithms to interrogate a video directly. The transcripts it generates provide more data for the firm's text-based search engine.
