Not really directly relevant to this, but YouTube makes captioning videos as painless as I can possibly imagine it being, and provides incredible automated and manual tools for doing so. I caption all of my videos on YouTube because it's the right thing to do, and I would do it even if it were more painful than it is, but I specifically use YouTube for everything because they make it so easy to add good captions (they also allow you to download the captions which can be converted to other formats and such). I don't know what kind of tools UCB could make available on their videos...but, the technology exists to community source the video captioning.
