It is an improved 8 mm film with a film width of 8 mm, but the screen area is 50% larger than the standard 8 mm film. 1965, in order to make full use of the film area, enlarge the picture, reduce the projection magnification, improve the definition and improve the particle phenomenon, Hysmans Kodak Company designed and produced this new type of 8 mm film. Its photographic picture is 5.39 mm wide and 4.03 mm high. Because of the need to expand the screen surface, the tooth hole of the film conveyor has also been improved accordingly. With its excellent screening quality, Super 8 movies are deeply loved by amateurs, and are widely used in scientific research, teaching, industry, commerce and other aspects, thus gradually replacing the old standard 8 mm movies, especially the audio copy combined with light, magnetism and vocal cords, which is extremely convenient to use.
