Gate dimensions are the width and height of the camera gate aperture, and by extension the film negative frame. Negative pulldown describes the film perforations 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 ...
In motion picture formats, the physical size of the film area between the sprocket perforations determines the image's size. The universal standard (established by William Dickson and Thomas Edison in 1892) is a frame that is four perforations high. The film itself is 35 mm wide (1.38 in), but the area between the perforations is 24.89 mm × 18 ...
The original version of Todd-AO used a frame rate of 30 per second, 25% faster than the 24 frames per second that was (and is) the standard; this was changed after the second film – Around the World in 80 Days - because of the need to produce (24 frame/sec) 35 mm reduction prints from the Todd-AO 65 mm negative.
The Ultra 16 format, with frame dimensions of 11.66 mm × 6.15 mm (0.459 in × 0.242 in), provides a frame size between standard 16 mm and Super 16—while avoiding the expense of converting a 16 mm camera to Super 16, the larger lens-element requirements for proper aperture field coverage on Super 16 camera conversions, and, the potential ...
Normally, 24 frames are needed for one second of film. In ordinary filming, the frames are photographed automatically, one after the other, in a movie camera. In special effects or animation filming, the frames are often shot one at a time. The size of a film frame varies, depending on the still film format or the motion picture film format.
A detriment is that the film grain size is thus increased because only part of the image is being expanded to full height. Films are designed to be shown in cinemas in masked widescreen format but the full unmasked frame is sometimes used for television, known as an open matte. In such an instance, a photographer will compose for widescreen ...

21:9 movies usually refers to 1024:429 ≈ 2.387, the aspect ratio of digital ultrawide cinema formats, which is often rounded up to 2.39:1 or 2.4:1 Ultrawide resolution can also be described by its height, such as "UW 1080" and "1080p ultrawide" both stands for the same 2560×1080 resolution.
