This startling bit of intelligence was conveyed to the trade by Paramount Pictures Corp. as the finale in a series of events which, whatever their contribution to motion picture technology, were not without humor. The playlet opened upon the arrival in New York of Loren L. Ryder, director of recording for Paramount and newlyinstalled prexy of the Society of Motion Picture Engineers. Acceding to the idea that he meet and exchange chit-chat with the trade press, Ryder donned his S.M. P.E. mantle and divested himself of the following pronouncements anent theatre television: 1. Video in picture houses is entirely feasible at the moment, and 1947 will see tele on full-size screens in several of the de-luxe theatres. 2. "Commercially satisfying" pictures photographed from cathode tube images would be perfected and introduced into key-city big theatres during 1947, with special events hogging the early programs.

The latter agreed with Ryder estimate of video's imminence, but hurriedly added, according to Variety, that "opposition from projectionists' Unions make their introduction an unknown quantity." This "opposition" takes the form, says Par. of you projectionist guys insisting upon handling the "intricate transition" from cathode image to the projection of the film, which job, adds Par, is held by video executives to require the "expert" ministrations of "tele engineers". Now, this is the same guff that is spread so assiduously by the broadcasters in an effort to stave off unionization of the tele field. In I. P. for Sept., 1946 (p. 3) we commented on the anguished cries of tele broadcasters for "expert engineering talent" (as opposed to Union Labor) in the following words: "I. P. will endorse the foregoing provided there be some foreseeable (Continued on page 34) INTERNATIONAL PROJECTIONIST • February 1947
