First known film is the first film (not including tests) made with the format and intended for release. Negative gauge is the film gauge (width) used for the original camera negative. Negative aspect ratio is the image ratio determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1× in the case ...
The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1. [1] Two common videographic aspect ratios are 4:3 (1. 3:1), [a] the universal video format of the 20th century, and 16:9 (1. 7:1), universal for high-definition television and European digital television. Other cinematic and video aspect ratios exist, but are used infrequently.
Letter-boxing is the practice of transferring film shot in a widescreen aspect ratio to standard-width video formats while preserving the film's original aspect ratio. The resulting video-graphic image has mattes of empty space above and below it; these mattes are part of each frame of the video signal.
In film, a widescreen film is any film image with a width-to-height aspect ratio greater than 4:3 (1.33:1). For TV, the original screen ratio for broadcasts was in 4:3 (1.33:1). Largely between the 1990s and early 2000s, at varying paces in different countries, 16:9 (e.g. 1920×1080p 60p) widescreen displays came into increasingly common use by ...
The Academy ratio of 1.375:1 (abbreviated as 1.37:1) is an aspect ratio of a frame of 35 mm film when used with 4-perf pulldown. [ 1 ] [ 2 ] It was standardized by the Academy of Motion Picture Arts and Sciences as the standard film aspect ratio in 1932, although similar-sized ratios were used as early as 1928.
During the silent era, aspect ratios varied widely, from square 1:1, all the way up to the extreme widescreen 4:1 Polyvision. However, from the 1910s, silent motion pictures generally settled on the ratio of 4:3 (1.33). The introduction of sound-on-film briefly narrowed the aspect ratio, to allow room for a sound stripe.
The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 aspect ratio tends to reflect post-2010 mass-market computer monitor, laptop, and entertainment products displays. On CRTs, there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square ...
For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [1] [2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction .
