Hobbit Movie to play at 48 frames/sec

Way back when, say Thomas Edison's time, movies were taken at quite low frame rates, as low as 12 frames/sec.  That's what made the real oldies move funny.  You must have seen Charlie Chaplin walking funny.  The movie film back then was slow, insensitive to light, and needed a 1/12 second exposure time to get a good image.  By the late 1920's Kodak had improved the film, and the movie makers had improved the lighting and frame rate standardized at 24 frame/sec for theater grade movies.  You need standardization because the same movie is played at thousands of different theaters, each with its own movie projector.  All those projectors need to run at the same speed unless you want the movie to run too fast or too slow as it moves from place to place.  
   The eye is a biochemical device, and by electronic standards, it is slow.  It takes many milliseconds for an image to fade away.  If a fresh image is flipped up on the screen before the old image fades from view the eye sees it as a continuous image.  It was found by experimentation, that if the movies ran at 48 frames/sec  a smooth flicker free movie resulted.  Then some genius experimenter discovered that the projector did not have to advance the film at 48 frames/sec.  He set the projector to advance the film (change the projected image) at half the rate the shutter ran.  Test audiences loved it, and it saved a lot of expensive film.  Speaking as one who has enjoyed thousands of theater movies over the years, I can say the motion illusion from 48 frame/sec flicker and 24 frame/sec film advance rate is very good, realistic, and enjoyable.
   In the constant search for a new gimmick to draw bigger movie audiences,  Peter Jackson is going to try filming at 48 frames/sec for the new Hobbit movie coming out next year.  Stand by for a lot of advertising hype about how much better it will look on screen due to revolutionary technical advances.  But I ain't gonna believe that hype.  I'll go see the flick, 'cause I am a Tolkien movie fan, not 'cause of running more frames per second.
