CowboyRobot writes "In the past five years there has been an 8x increase in the amount of content being generated per every two-hour cinematic piece. Although 3D is not new, modern 3D technologies add from 100% to 200% more data per frame. In 2009, "Avatar" was one of the first movies to generate about a petabyte of information. "The Hobbit: An Unexpected Journey" was shot in a new digital format called High Frame Rate 3-D (HFR 3-D), which displays the movie at 48 frames per second (fps), twice the standard 24-fps rate that's been in place for more than 80 years."
