  •  24 FPS Vs. 48 FPS (10+ / 0-)

    Peter Jackson's 'The Hobbit: An Unexpected Journey' is one of the first major films to try 48 frames per second instead of the normal 24 frames per second.

    But is more always better?

    From Movieline: "The Science of High Frame Rates, Or: Why 'The Hobbit' Looks Bad At 48 FPS"

    Do scientific theories about the way our brains perceive images and reality — truth unfolding onscreen, in front of our eyes — support Jackson’s brave new vision for cinema, or undermine it?

    There is a great gulf between the cinematic look of 24 fps, the traditional rate at which film images are presented in succession to simulate moving images on a screen, and 48 fps. The latter packs more visual information into each second of film, for better and worse. Jackson and his fellow HFR enthusiasts (including James Cameron and Douglas Trumbull) argue that 48 fps and even higher frame rates result in greater clarity and a closer approximation to real life.  They also contend it reduces motion blur, thus improving the look of 3-D images.

    But scientists and researchers in the field of consciousness perception say that the human brain perceives reality at a rate somewhere between 24 fps and 48 fps — 40 conscious moments per second, to be more exact — and exceeding the limit of the brain’s speed of cognition beyond the sweet spot that connotes realism is where Jackson & Co. get into trouble.
