Though the vast majority of film is silent, there are several types of film that include a soundtrack.
16mm film may have either an optical or a magnetic soundtrack. In either case, the film will have sprocket holes along only one edge, and the soundtrack will be along the opposite edge.
Optical sound looks like a white waveform that is part of the film.
Magnetic sound looks like a solid brown stripe that has been glued to the surface of the film.
There is a third type of 16mm sound film called Full Coat, though it is used only by professional filmmakers. Unlike the first two formats, full coat 16mm film is a sound-only format, with no images on the film. It usually accompanies a reel of silent 16mm film. It looks like single-perforated 16mm film, except the surface will be solid brown instead of a series of image frames.
Super 8mm film shot after August 1973 may have a magnetic soundtrack. If so, there will be a brown stripe glued to the surface of the film on the edge opposite the sprocket holes.
In extremely rare cases, Regular 8mm film may have a magnetic soundtrack. If so, there will be a brown stripe glued to the surface of the film on the edge with the sprocket holes.
