Just launched a new website, notr.tv
It turns out that it’s possible to overlay HTML on top of YouTube players in most browsers (with smartphone browsers being the main exception). And the YouTube API gives you a lot of information about video playback. Combine the two, and you can annotate other people’s videos.
The obvious use is generating Downfall parodies. And Osama bin Laden and Pope parodies.
But there is also a lot of content out there that isn’t in English. And a lot of YouTube users who don’t understand English. So there is a plenty of potential for the crowd-sourcing of subtitles.
At the end of the day, I don’t know how this service is going to be used, but it will be interesting to find out.
