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, which displays the movie at 48 frames per second, twice the standard 24-fps rate that's been in place for more than 80 years." But with digital storage transcending some other limitations of conventional projection techniques, it's not just framerate that directors are now able to play with more easily; it's the length of movies themselves, which stats suggest just keep getting longer.
