I probably watch videos online more than I actually watch television. However, search engines can't index video files as easily as text. Therefore, the race is on to see who will become the GOOGLE of video search. Several search engines are implementing different techniques in order to index these videos. One technique is to scan the script. Everything said in a clip is tracked through voice recognition soft-ware, closed-captioned information, or a combination of the two. Blinkx and TVEyes have tested this technique. However, just because someone or something's name is included in a script doesn't mean that thing is in the actual clip. Another popular technique is to analyze links and metadata. Dabble and Google are testing this technique out. Here conventional search spiders scan the text around a video and the pages that point or link to that page. This is probably the most effiecient way to index videos.
As for searching for a particular video, I "youtube it" and cross my fingers..lol
