Hey all-

What's a Kodak sound coating? I asked if a S8 film for sale was sound or silent and they said it had a Kodak Sound Coating.

Thanks!

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.

Timothy,

It sounds like that film had been sent to Kodak to be sound striped. Kodak referred to that process as Kodak Sonotrack Coating. I've done that with silent films so I could record a soundtrack. I also picked up this on eBay from a seller who had done the same thing:

This collector mixed his own music and sound effects and did a great job.

I think there's room for just one more film.....
