Film Mutilation — John M. Joy 21
Conclusions and Recommendations Relating to a Plan for Reducing Film Mutilation
1. Film Protecting Process
Some method of treating film which will increase the resistivity of the emulsion to scratching or prolong the life of the film in any way is highly desirable. Several film protecting processes are under investigation, but definite reconamendations are withheld until completion of the tests.
2. Mutilation for Signal
It is suggested that the entire question of providing a standard method which can be used as a signal for throwing over to a second projector be taken up with the Standards Committee of the Society of Motion Picture Engineers.
Elimination of the use of tin foil for signal purposes might be brought about by pointing out to exhibitors that this practice creates a fire hazard and could be construed as a violation of fire regulations. An inspector of the New York Fire Department who was inspecting a New York exchange, on being shown a piece of film pasted with tin foil, stated that he would consider it a dangerous practice.
3. Exchanges should constantly insist on the most rigid examination and be on the watch to see that carelessness does not enter into the inspection. It is important that damaged reels be thrown out when they are no longer in a condition to be used. It is not economy to continue to use prints which have become worn and brittle through long use.
4. Subjects for Technical Investigation
A. Improvements in reel construction.
B. Uniform methods of splicing, especially with a view to inducing all the theatres to use some simple and low cost machine.
C. Has the general use of high intensity sources of light in projectors anything to do with the cause of film becoming brittle in service?
D. Is there any serious shrinkage of the fihn produced by intense heat coming from high powered light sources which would be sufficient to sometimes cause the film to ride the sprocket teeth?
E. To what extent does excessive heating have an injurious effect on the life of motion picture film?
