 | | Double 8mm, called such because the film is 16mm's wide, with perforations that are identical in size and pitch to that of 16mm film....although with an extra perforation which is required since the 8mm frame is 1/4th that of a 16mm frame. |
 | | After processing, the film is slit down the middle yielding two lengths of 8mm width movie film, which are spliced together in their order of the first half in front, yielding a total length of projection footage in either 50ft(from 25ft spools), 100ft(from 50ft spools...now long discontinued in use), and 200ft (from 100ft spools). |
 | | It wasn't until Super 8mm was introduced in late 1964 and officially on the market for 1965 that simple drop in loading without the need to have to expose a second side of the film, came onto the scene and changed drastically the entire 8mm filmmaking movement. |
