Robin Good: Hadza is a new web service which leverages the power of video clips shot by smartphones at public events to recreate, after-the-fact, a multiple point of view video recording of those moments.
You can either shoot your clips with Hazda, or upload to Hazda any clip that is already on YouTube.
Hazda's algorithm automatically groups videos together into "events" based on the GPS and time stamps they receive (videos are grouped together within 1000 meters and 20 seconds of each other.)
The service is free to use.
