Kodak introduced the 8mm filmstrip in 1932 as a less expensive home movie alternative to 16 and 35mm. A regular 16mm film was used in 25ft/7.5m spools, with an 8mm camera exposing frames (3.3 x 4.5 mm) on both the left and right area of the film. After processing, the 16mm film was slit into two separate 8mm strips, and then spliced together to create a 50ft/15m roll.
We introduced the Super 8 format in 1965, in a new easy-to-load cartridge. Super 8 film has smaller sprocket holes, resulting in a much larger image area (4.01 x 5.79mm). This gives an exposure on the same film width, with much higher quality images.
Super 8 is a different exposure format compared to 8mm, and requires different equipment (camera and projector).
