Widescreen images are displayed within a set of aspect ratios used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than 4:3 (1.33:1).
70 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. 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 stripes, holding six tracks of stereophonic sound. Although later 70 mm prints use digital sound encoding, the vast majority of existing and surviving 70 mm prints pre-date this technology.
IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters known for having very large screens with a tall aspect ratio and steep stadium seating, with the 1.43:1 ratio format being available only in few selected locations.
CinemaScope is an anamorphic lens series used, from 1953 to 1967, and less often later, for shooting widescreen films that, crucially, could be screened in theatres using existing equipment, albeit with a lens adapter.
Cinerama is a widescreen process that originally projected images simultaneously from three synchronized 35mm projectors onto a huge, deeply curved screen, subtending 146-degrees of arc. The trademarked process was marketed by the Cinerama corporation. It was the first of several novel processes introduced during the 1950s when the movie industry was reacting to competition from television. Cinerama was presented to the public as a theatrical event, with reserved seating and printed programs, and audience members often dressed in their best attire for the evening.
Todd-AO is an American post-production company founded in 1953 by Mike Todd and Robert Naify, providing sound-related services to the motion picture and television industries. The company retains one facility, in the Los Angeles area.
A roadshow theatrical release or reserved seat engagement is the practice of opening a film in a limited number of theaters in major cities for a specific period of time before the wide release of the film. Roadshows would generally mimic a live theatre production, with an upscale atmosphere as well as somewhat higher prices than during a wide release. They were commonly used to promote major films from the 1920s–60s and build excitement.
Panavision Inc. is an American motion picture equipment company founded in 1954 specializing in cameras and lenses, based in Woodland Hills, California. Formed by Robert Gottschalk as a small partnership to create anamorphic projection lenses during the widescreen boom in the 1950s, Panavision expanded its product lines to meet the demands of modern filmmakers. The company introduced its first products in 1954. Originally a provider of CinemaScope accessories, the company's line of anamorphic widescreen lenses soon became the industry leader. In 1972, Panavision helped revolutionize filmmaking with the lightweight Panaflex 35 mm movie camera. The company has introduced other cameras such as the Millennium XL (1999) and the digital video Genesis (2004).
70 mm Grandeur film, also called Fox Grandeur or Grandeur 70, is a 70 mm widescreen film format developed by William Fox through his Fox Film and Fox-Case corporations and used commercially on a small but successful scale in 1929–30.
Technirama is a screen process that has been used by some film production houses as an alternative to CinemaScope. It was first used in 1957 but fell into disuse in the mid-1960s. The process was invented by Technicolor and is an anamorphic process with a screen ratio the same as revised CinemaScope (2.35:1), but it is actually 2.25:1 on the negative.
Super Technirama 70 was the marketing name for a special type of deluxe film exhibition that was most popular in the 1960s. It was the 70 mm version of the Technirama exhibition format.
Super Panavision 70 is the marketing brand name used to identify movies photographed with Panavision 70 mm spherical optics between 1959 and 1983. It has since been replaced by Panavision System 65.
Kinopanorama is a three-lens, three-film widescreen film format. Although Kinopanorama was initially known as Panorama in the Soviet Union the name was later revised to include its current name prior to the premiere screenings in Moscow in 1958. In some countries, including Cuba, Greece, Norway and Sweden, it was usually marketed as Soviet Cinerama. When Great Is My Country and The Enchanted Mirror, were exhibited at the Mayfair Theatre in New York City in 1958, it was briefly advertised as Cinepanorama. Kinopanorama is for the most part identical in operation to that of Fred Waller's American-designed Cinerama format.
Ultra Panavision 70 and MGM Camera 65 were, from 1957 to 1966, the marketing brands that identified motion pictures photographed with Panavision's anamorphic movie camera lenses on 65 mm film. Ultra Panavision 70 and MGM Camera 65 were shot at 24 frames per second (fps) using anamorphic camera lenses. Ultra Panavision 70 and MGM Camera 65's anamorphic lenses compressed the image 1.25 times, yielding an extremely wide aspect ratio of 2.76:1.
Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen.
The Arri Alexa is a digital motion picture camera system developed by Arri. The Arri Alexa was introduced in April 2010 and was Arri's first major transition into digital cinematography, after previous efforts including the Arriflex D-20 and D-21.
In motion picture technology—either film or video—high frame rate (HFR) refers to higher frame rates than typical prior practice.
The Arriflex 765 is a 65 mm movie camera created by Arri in 1989.
