Because of its lower costs, 16mm film is typically used for productions with smaller budgets. If you intend to shoot 16mm but release your project as 4-perf 35mm, you should use Super 16mm film. It has perforations along only one edge and a larger frame that more closely matches the 4-perf 35mm aspect ratio. 16mm format Super 16mm 35mm film is most commonly used for theatrical releases, with 4 perforations per frame (4-perf ) being the most prevalent version. Another common version uses 3 perforations per frame (3-perf ). There are other versions of 35mm, such as 8-perf, but they are not currently supported by Cinema Tools. 35mm format 4-perf 35mm format 3-perf Perforations Camera and projection equipment uses the perforations, also known as sprocket holes, along one or both edges of film to pull it past the shutter. 16mm Film 16mm film has a single perforation for each frame, which comes out to 40 perforations per foot. 16mm is available as single perforated (perforations along one edge only, allowing space for an optical track, or in the case of Super 16mm film, for a larger frame) and double perforated (perforations along both edges). Cinema Tools supports single and double perforated 16mm film as long as it has a key number every 20 frames. See Key Numbers for more information. 230 Appendix A Film Background Basics

35mm film is most commonly used for theatrical releases, with 4 perforations per frame

(4-perf) being the most prevalent version. Another common version uses 3 perforations

Perforations

Camera and projection equipment uses the perforations, also known as

sprocket holes

along one or both edges of film to pull it past the shutter.

16mm Film

16mm film has a single perforation for each frame, which comes out to 40 perforations

per foot. 16mm is available as single perforated (perforations along one edge only, allowing

space for an optical track, or in the case of Super 16mm film, for a larger frame) and

double perforated (perforations along both edges). Cinema Tools supports single and

double perforated 16mm film as long as it has a key number every 20 frames. See
