This manual for the preparation of original motion picture film for printing discusses the importance of careful handling of the original camera film, briefly reviews the professional production system for making 16mm films, and presents the advantages and disadvantages of sending the original camera film together with the work print to a laboratory for cutting and matching in-house. Equipment and facilities needed if the film is to be cut in-house (and then sent to a laboratory for printing) are described, procedures for organizing the editing and finding the desired shots in the original film are detailed, and step-by-step instructions illustrated with line drawings are provided for cutting and splicing the film, as well as the use of A and B rolls to avoid overlapping frames when splicing. Special effects such as dissolves and superimpositions that can be produced by the laboratory during the printing process are also explained, and guidelines are provided for marking the film and writing instructions for the laboratory.
