Super 8 mm film, commonly known as Super 8 film and often simply "Super 8", is a motion picture film format released in 1965 by Eastman Kodak as an improvement of the older "Double" or "Regular" 8 mm home movie format.
The film is nominally 8 mm wide, exactly the same as the older standard 8mm film, and also has perforations on only one side.
However, the dimensions of the perforations are smaller than those on older 8 mm film, which allowed the exposed area to be made larger. The Super 8 standard also specifically allocates the border opposite the perforations for an oxide stripe upon which sound can be magnetically recorded.
There are several different varieties of the film system used for shooting, but the final film in each case has the same dimensions. By far the most popular system was the Kodak system.
