Live Earth (officially written LiVEARTH), a trio of IT workers who invented an application that helps bands turn their live performances into music videos, was awarded the grand prize at Billboard Japan's first Live Music Hackasong on Jan. 26.

The competition rewards groups and individuals who use new forms of technology to create innovative stage performances. The presentation and ceremony was held at Billboard Live Tokyo in the capital's Roppongi neighborhood.

The winning app, Live CJ (Camera Jockey), automatically edits real-time recordings captured using multiple cameras at a concert and turns the footage into a single video. It uses an algorithm that switches between cameras depending on the loudness of the instruments played.
