Super 8 mm film is a motion-picture film format released in 1965 by Eastman Kodak as an improvement over the older "Double" or "Regular" 8 mm home movie format. The formal name for Super 8 is 8-mm Type S, distinguishing it from the older double-8 format, which is called 8-mm Type R. Unlike Super 35 (which is generally compatible with standard 35 mm equipment), the film stock used for Super 8 is not compatible with standard 8 mm film cameras.
The film is nominally 8 mm wide, the same as older formatted 8 mm film, but the dimensions of the rectangular sprocket hole perforations along one edge are smaller, which allows for a larger image area. The Super 8 standard also allocates the border opposite the perforations for an oxide stripe upon which sound can be magnetically recorded.
