1、CMPTE STANDARD SMPTE 153-2001 Revision of ANSVSMPTE 153-1996 a for Motion-Picture Film (8-mm Type S) - - 16-mm Film Perforated 8-mm Type S (1 -4) - Printed Areas _ Page 1 of 2 pages 1 Scope This standard specifies the location and size of the printed picture area for negative/positive and reversal p
2、rnting operations on 16-mm motion-picture film per- forated 8-mm type s, 2R-1664 or 2R-1667, in row positions 1 and 4. 2 Dimensions 2.1 The dimensions shall be as given in figure 1 and table 1. 2.2 Dimension H is measured from the minus-2 perforation because this perforation position coincides with
3、the perforation used to position the resulting 8-mm print in the projector (see annex A.l). 2.3 Two images may be printed on this film. The image area on the left side, not shown in the figure, is symmetrical but opposite in direction to that shown on the right side. The dimensions for each image ar
4、ea, however, are taken from the nearest edge of the film as shown. NOTES 1 The reduction ratio of prints made from 16-mm negative or reversal originals shall be approximately 1.8:l. The cor- rect ratio is controlled by dimensions C and D. 2 The vertical dimension B of the reduced 8-mm type S image o
5、f the original camera aperture image should be nominally centered on the horizontal centerline of the per- foration although the exact location will be determined by dimension H and its tolerance. 3 The direction of film travel shown in figure 1 is to aid in illustrating the minus-2 perforation and
6、is the direction of motion in the projector for the resulting 8-mm print if the figure is as seen from the light source of a projector used for direct front projection. 4 If photographic audio is to be applied to the print, it is necessary to consider the required compatibility between this standard
7、 and the strong trade preference that a clear septum not appear between the edge of the printed picture and the edge of the printed track. This standard allows overlap (double) printing of adjacent areas of the printed picture and printed track without permitting undesirable incursions of one area i
8、nto the restricted area of the other. A suggested value of 0.0015 in (0.038 mm) more than minimum may be used. Copyright 8 2001 by THE SOCIEM OF MOTION PICTURE AND TELEVISION ENGINEERS 595 W.

This designation is necessary only when the film stock is wider than its end use and more than one combination of perforation rows is possible. The perforation rows are numbered starti
13、ng at the reference edge, which is the edge nearest to that row of perforations which is retained in the slitting operation. The row of perforations which is discarded is given the number O. Negative or intermediate films which are not slit may contain a O-numbered row of perforations if that perforated row corresponds to the dis- card row of perforations on the subsequent print stock.
