276 ASA COMMITTEE ON STANDARDS, Z22 March
Z22 . 68 Buzz-Track Test Film for 35-Millimeter Motion Picture Sound Reproducers
Each of these proposals covers a test film which is now in general use.
Two proposed standards for dimensions of 200-mil push-pull sound tracks were also submitted by the Motion Picture Research Council. Since these proposals, did not include tolerances, the Chairman appointed the following Committee to prepare revised proposals conforming to other sound track standards: G. R. Crane, chairman, M. C. Batsel, W. F. Kelly, L. L. Ryder, and W. C. Miller.
The following 15 standards were referred to the Society of Motion Picture Engineers for revision on November 5, 1945 :
Z22 . 7-1941 Camera Aperture for 16-Millimeter Silent Motion Picture Film Z22 . 8-1941 Projector Aperture for 16-Millimeter Silent Motion Picture Film Z22 . 13-1941 Camera Aperture for 16-Millimeter Sound Motion Picture Film Z22 . 14-1941 Projector Aperture for 16-Millimeter Sound Motion Picture Film Z22 . 19-1941 Camera Aperture for 8-Millimeter Silent Motion Picture Film Z22 . 20-1941 Projector Aperture for 8-Millimeter Silent Motion Picture Film Z22 . 34-1930 Cutting and Perforating Negative and Positive Raw Stock for 35Millimeter Motion Picture Film
Z22 .4-1941 Projection Reels for 35-Millimeter Motion Picture Film Z22 . 1 1-1941 Projection Reels for 16-Millimeter Motion Picture Film Z22 . 23-1941 Projection Reels for 8-Millimeter Silent Motion Picture Film Z22 . 26-1941 Sensitometry for Motion Picture Film Z22 . 24-1941 Film Splices Negative and Positive for 16-Millimeter Silent Motion
Picture Film Z22 . 25-1941 Film Splices Negative and Positive for 16Millimeter Sound Motion
Picture Film
Z22 . 6-1941 Projector Sprockets for 16-Millimeter Motion Picture Film Z22 . 18-1941 8-Tooth Projector Sprockets for 8-Millimeter Motion Picture Film
It is hoped that the Society will submit recommendations for revision of these standards at an early date.
At the request of Eastman Kodak Company, War Standards Z52.511946 Base Point for Distance Scales 16-Millimeter Cameras and Z52.50-1946 Lens-Registration Distance 16-Millimeter Cameras were referred to .the Society of Motion Picture Engineers on February 4, 1947, for recommendations for American Standards.
Fader Setting Instructions Z22. 32-1941 was unanimously withdrawn since the practice described is no longer followed.
The attention of the Committee was drawn to the apparent omission of silent pictures from the Scope as originally adopted. Since this w^s, of course, unintentional the following revision of the Scope was proposed and adopted :
