Eight Milimeter (8MM)
8 mm is a reference to the motion picture film format that utilizes an 8 mm wide filmstrip. 8 mm file is available in two forms: Super 8 and standard 8 mm film. Standard (or regular) 8 mm film, available to consumers in 1932, is actually 16 mm film that is fed through the camera twice to yield 4x the amount of frames. Regular 8 film has a frame size of 4.8 mm x 3.5 mm and is filmed at 16 fps (frames per second). Super 8 film was introduced in 1965 and provided greater film quality and ease of use. The film was contained in a cartridge that did not have to be re-threaded into the camera halfway through filming. The film got its name due to the expanded image area that resulted from the reduced and further spaced perforations.
