70 mm film (or 65 mm film) is a wide high-resolution film gauge for motion picture photography, with a negative area nearly 3.5 times as large as the standard 35 mm motion picture film format.[1] As used in cameras, the film is 65 mm (2.6 in) wide. For projection, the original 65 mm film is printed on 70 mm (2.8 in) film. The additional 5 mm contains the four magnetic strips, holding six tracks of stereophonic sound. Although later 70 mm prints use digital sound encoding (specifically the DTS format), the vast majority of existing and surviving 70 mm prints pre-date this technology.
