TED has developed a cool new technology that makes it possible to search, caption and translate TED talks. Each talk will now come with an transcript. What's cool is that you can click on any phrase in the transcript and you will jump to that point in the video. If you go to my talk, for example, and click on “open interactive transcript” you can see this in action. What this means is that videos will now be Google searchable.
