3-D Projection

A11 Up-To-Date Report by the SMPTE and MPRC on Proper Projection Techniques and Equipment Required for 3-D

Technical problems of converting the motion picture industry to 3eD are many and varied. There are many new things which will have to be learned, and some which will have to be forgotten. In order to help supply some of the answers, the Society of Motion Picture and Television Engineers, working with the Motion Picture Research Council, has been attempting to develop standards and proper procedures to be used for the projection of three dimensional motion pictures.

As a result of their work, it has been possible to give some semblance of order

to the confused condition that prevailed i

when 3-D hrst made its presence felt. Since the entire situation is still Huid it is possible that some of the things in this report will not be true six months or a year from now. However, on the basis of the 3-D films now in release, or for those to be released in the foresee

able future, the information found here will be an accurate guide to equipment requirements and proper projection procedures.

Magazines. Reels and Spindles Size of projection reels and magazines for third dimension features is the initial standardization question for theatre owners. Current 3-D pictures come on two separate films that project together from two machines. For the majority of houses equipped as they are with two or at most three projectors this rules out the itchangeoverf The amount of 3-D film that can be run between stops-toreload is limited to the capacity of a single reel.

THIS VIEW OF THE AUDIENCE at the State in Minneapolis is by now a well known scene.

BRIEF: The average exhibitor . . . as well as the man in the projection booth . . . is today a bit confused about just exactly what is involved in installing and projecting three-dimensional films . . . Just what equipment will I need . . . what will that equipment (lo . . . and how will I use this equipment . . . are a few of the questions uppermost in (he minds of theatremen.
