alteration to standard 35 mm photography to create a 2.00:1 aspect ratio and economize on film. By using a negative area similar to that of the Super 35 frame (which utilizes the full width of a 35 mm film frame "perf-to-perf" as opposed to traditional 35 mm which utilizes a smaller area of the 35 mm frame offset to the right to accommodate space for an optical soundtrack) combined with 3-perf frame size (as opposed to standard 35 mm photography which uses four perforations per frame). The Univisium camera would use an aperture opening of 24mm × 12mm (.945" × .472") and three perforations per frame, which would eliminate the waste associated with 2.40:1 Super 35 mm photography (wherein nearly 50% of the frame is discarded) by creating a natural 2.00:1 aspect ratio utilizing the whole film area. In addition to using the full film area, using three perforations per frame as opposed to four equates to using 25% less film for the same shooting time. With the traditional four perforations per frame, 35 mm film (at 24 frames per second) runs at 90 feet per minute (4 minutes 26 seconds per 400 feet of film), three perforations per frame runs at 67.5 feet per minute (5 minutes 56 seconds per 400 feet of film). This would mean each magazine of film would have 33% more shooting time and a production that shot the same overall length of time as a four-perforation film would use 25% less film. The proposal also points out that the 2.00:1 aspect ratio can be achieved using standard spherical lenses, which, compared to their anamorphic counterparts, are cheaper, faster (require less light), and have more photographic depth of field and less visual imperfections. There are also a greater selection of spherical prime and zoom lenses than there are anamorphic lenses. 3-perf also results in a quieter camera than 4-perf as there is less intermittent movement per frame. The format also calls for shooting 25 frames per second, which eliminates problems associated with transferring film to video in the PAL and SECAM system and is still fairly simple to transfer to the NTSC video format. 35 mm Univisium projection proposal Storaro suggests a renovation to standard film projectors to present a 3-perf frame and eliminate the need for an anamorphic print to be made (to optically squeeze the 2:1 3-perf aspect ratio into a 1.33:1 4-perf
