Synchronized 16-mm Sound and Picture for Projection at 16 Frames per Second

George E. H. Hanson

This paper describes a method of re-recording 35-mm sound track to obtain a 16-mm track, which will reproduce synchronously with a 16-mm picture projected at 16 frames per second. The only necessary modification of a standard re-recording channel to perform this operation is the substitution of an 1800-revolution-per-minute synchronous motor for the standard 1200-revolution-per-minute motor on one 35-mm soundhead.
