Is the future digital cinema? A new company called MaxiVision believes that film merely needs a new lease on life. Indeed, the company argues persuasively that, with HDTV in the wings, movie theatres must improve or die.
The "MaxiVision 48" name is derived from the system's main feature: the use of 48 frames per second instead of the standard 24. This has been done before -- some early Imax films ran at 48 fps -- but doubling frame rate means doubling the cost of films and prints, and also cutting the running time of a reel in two. MaxiVision has a different way of doing things. Consider a present-day strip of 35 mm film:
Two aspects may strike you. First, some of the precious image space is taken up by the optical sound tracks (the bands at the left). Second, there seems to be rather a lot of wasted space between each of the images. Perhaps you know that this waste space didn't use to exist. However films are no longer shot at the old 1.33:1 aspect ratio. The images you see on this film strip have an aspect ratio of 1.85:1 (anamorphic lenses are used on some films to get an even wider film). And so blank bars are left above and below the picture, just as in letterboxed video films.
The frame now takes up the full width of the film stock, its height occupying three sprocket holes instead of four. This format cuts film use by 25%, and yet yields a picture that is nearly 32% larger. Not only will the larger image be sharper, but it will also be brighter. The film saving makes it possible to run the film at double speed, with much less flicker and with much better representation of motion. * * * Will MaxiVision 48 catch on?
