Stop-Frame Cinematography with Synchronized Sound: A Technique for Recording in School Classrooms

Interactions between teachers and pupils in classroom situations may be studied and teaching techniques evaluated in a kind of “debriefing” if film and audiotape recordings are made synchronously during the class. In the technique described, filming is done at one frame every two seconds using two 16mm recording cameras — one with a fixed-focus lens, the other with a zoom lens. A number of microphones, including a lavalier radio-microphone, feed sound to a four-track, three-head recorder; camera-synchronizing signals are recorded on one of the tape tracks. A refinement of the technique, using a half-frame still camera and a synchronized cassette recorder, is also discussed briefly.
