Discusses and demonstrates the laboratory procedures involved in the production of a 16 mm. sound, color film. Part 1 follows the original film and a 1/4-inch audiotape through the following procedures: processing the original, dubbing the sound to 16 mm. magnetic film, making a work print, and edge numbering the original and the work print. Part 2 takes the edited work print and magnetic sound through the processes of conforming, transferring to optical sound and color balancing in order to make the composite answer print.
