Mondo Knows Facts

Some films are shot with three perforations a frame

Using less film per frame cuts stock costs and allows longer takes Standard 35mm uses four perforations per frame. A three-perforation frame is slightly shorter and wider, so a given length of film holds more frames, which saves stock and lets a camera run longer between reloads. The format suits widescreen productions that do not need the full silent-era frame height. It sits in Mondo's movies & tv collection, one of 200 facts that each trace back to the reference below.
