Optical format is a hypothetical measurement approximately 50% larger than the true diagonal size of a solid-state photo sensor.The use of the optical format means that a lens used with a particular size sensor will have approximately the same angle of view as if it were to be used with an equivalent-sized video camera tube (an "old-fashioned" TV camera).
The common 1" outside diameter circular video camera tubes have a rectangular photo sensitive area about 16 mm on the diagonal, so a digital sensor with a 16 mm diagonal size is a 1" video tube equivalent. The name of a 1" digital sensor should more accurately be read as "one inch video camera tube equivalent" sensor.
The variant called Super 16 mm, Super 16, or 16 mm Type W is an adaptation of the 1.66 (1.66:1 or 15:9) aspect ratio of the "Paramount format" [8] to 16 mm film. It was developed by Swedish cinematographer Rune Ericson in 1969, [ 9 ] using single-sprocket film and taking advantage of the extra room for an expanded picture area of 12.52 mm × 7. ...
The modern era of 16 mm cameras is concurrent with that of 35 mm for both the same reasons as 35 mm as well as an additional change: the creation of the Super 16 format by Rune Ericsson in 1971. The format expanded the usable film negative horizontally, which required a larger film gate and necessitated either specialized conversion of machined ...

Once the film was developed it was sliced down the middle and the ends attached, giving 50-foot (15 m) of Standard 8 film from a spool of 25-foot (7.6 m) of 16 mm film. 16 mm cameras, mechanically similar to the smaller format models, were also used in home movie making but were more usually the tools of semi professional film and news film makers.
For 35 mm film these are 0.1866" and 0.1870" (4.740 mm and 4.750 mm); for 16 mm film they are 0.2994" and 0.3000" (7.605 mm and 7.620 mm). This distinction arose because early nitrocellulose film base naturally shrank about 0.3% in processing due to heat, so film printing equipment was designed to account for a size difference between its ...
Film-out of standard-definition video – or any source that has an incompatible frame rate – is the up-conversion of video media to film for theatrical viewing. The video-to-film conversion process consists of two major steps: first, the conversion of video into digital film frames which are then stored on a computer or on HD videotape; and secondly, the printing of these digital film ...
