List of film formats
Encyclopedia
This list of film formats catalogues formats developed for shooting or viewing motion pictures, ranging from the Chronophotographe format from 1888, to mid-20th century formats such as the 1953 CinemaScope
CinemaScope
CinemaScope was an anamorphic lens series used for shooting wide screen movies from 1953 to 1967. Its creation in 1953, by the president of 20th Century-Fox, marked the beginning of the modern anamorphic format in both principal photography and movie projection.The anamorphic lenses theoretically...

 format, to more recent formats such as the 1992 IMAX HD format. To be included in this list, the formats must all have been used in the field or for test shooting, and they must all use photochemical images that are formed or projected on a film base
Film base
A film base is a transparent substrate which acts as a support medium for the photosensitive emulsion that lies atop it. Despite the numerous layers and coatings associated with the emulsion layer, the base generally accounts for the vast majority of the thickness of any given film stock...

, a transparent substrate which supports the photosensitive emulsion.

As well, the formats must have been used to make more than just a few test frames. The camera must be fast enough (in frames per second) to create an illusion of motion consistent with the persistence of vision
Persistence of vision
Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina....

 phenomenon. The format must be significantly unique from other listed formats in regard to its image capture or image projection
Movie projector
A movie projector is an opto-mechanical device for displaying moving pictures by projecting them on a projection screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras.-Physiology:...

. The format characteristics should be clearly definable in several listed parameters (e. g., film gauge, aspect ratio, etc.).

Legend

  • Format is the name of the process; some formats may have multiple names in common usage.
  • Creator is the individual or company most directly attributable as the developer of the system.
  • Year created usually refers to the earliest date that the system was used to completion (i.e. projection), but may refer to when it was developed if no known film was made.
  • First known film is the first film (not including tests) made with the format and intended for release.
  • Negative gauge is the film gauge
    Film gauge
    Film gauge is a physical property of photographic or motion picture film stock which defines its width. Traditionally the major film gauges in usage are 8 mm, 16 mm, 35 mm, and 65/70 mm...

     (width) used for the original camera negative.
  • Negative aspect ratio is the image ratio
    Aspect ratio (image)
    The aspect ratio of an image is the ratio of the width of the image to its height, expressed as two numbers separated by a colon. That is, for an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this...

     determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1x in the case of spherical lenses).
  • Gate dimensions are the width and height of the camera gate aperture
    Film gate
    The film gate is the rectangular opening in the front of a motion picture camera where the film is exposed to light. The film gate can be seen by removing the lens and rotating the shutter out of the way...

    , and by extension the film negative frame.
  • Negative pulldown describes the film perforations
    Film perforations
    Film perforations, also known as perfs, are the holes placed in the film stock during manufacturing and used for transporting and steadying the film. Films may have different types of perforations depending on film gauge, film format, and the intended usage...

     per frame, the direction of film transport, and standard frame speed. Film transport is assumed to be vertical unless otherwise noted, and standard frame speed is assumed to be 24 frames per second unless the film is otherwise noted or has no standard. Silent film has no standard speed; many amateur formats have several common speeds, but no standard.
  • Negative lenses indicates whether spherical (normal) or anamorphic lenses are used on the original camera negative, and if anamorphic lenses, what anamorphic power is used.
  • Projection gauge is the film gauge
    Film gauge
    Film gauge is a physical property of photographic or motion picture film stock which defines its width. Traditionally the major film gauges in usage are 8 mm, 16 mm, 35 mm, and 65/70 mm...

     (width) used for the release print.
  • Projection aspect ratio is the image ratio
    Aspect ratio (image)
    The aspect ratio of an image is the ratio of the width of the image to its height, expressed as two numbers separated by a colon. That is, for an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this...

     determined by the ratio of the projection dimensions multiplied by the anamorphic power of the projection lenses (1x in the case of spherical lenses). This is also known as the intended theatrical aspect ratio.
  • Projection dimensions are the width and height of the projector aperture

     plate, and by extension the film frame area which is projected. The aperture plate always very slightly crops the frame.
  • Projection lenses indicates whether spherical (normal) or anamorphic lenses are used on the projector, and if anamorphic lenses, what anamorphic power is used.


Formats are listed in chronological order and by release date in the case of multiple formats within one year, if this can be determined. Undated formats are listed at the bottom in alphabetical order.
