Super 8 mm film is a motion-picture film format released in 1965 [1] [2] [3] ... Sound film is typically filmed at a speed of 18 or 24 frames per second. [23]
The frame size of regular 8 mm is 4.8 mm × 3.5 mm, and 1 meter of film contains 264 pictures. Normally, Double 8 is filmed at 16 or 18 frames per second. Common length film spools allowed filming of about 3 to 4 + 1 ⁄ 2 minutes at 12, 15, 16, and 18 frames per second.
The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras, a lens of a given focal length gives a narrower field of view in such cameras.
In the early 1960s, a new filming and projection standard of 18 frames per second was introduced, and films with sound increased the speed again to 24 frames per second; [2] many cameras and projectors include a multi-speed facility. The standard 8 mm format was displaced by the Super 8 mm film format, which offers cartridge loading, a 50% ...
This list of motion picture 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 format, to more recent formats such as the 1992 IMAX HD format.
The most commonly used definition of crop factor is the ratio of a 35 mm frame's diagonal (43.3 mm) to the diagonal of the image sensor in question; that is, = /. Given the same 3:2 aspect ratio as 35mm's 36 mm × 24 mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of the crop factor.
The first camera to be formatted for the new film was the Kodak M2. During the late 1960s, cameras were only formatted to film at 18 frames per second, but as technology improved, speeds such as 24 frame/s (the motion-picture standard) and faster speeds (for slow-motion filming) were incorporated into camera mechanics.
