1、SMPTE RECOMMENDED PRACTICE RP 53-1 993 Revision of RP 53-1983 Scene-Change Methods for Y% Printing 35-mm, 16-mm and 8-mm Type S Motion-Picture Film 1 Scope 1.1 This practice specifies the dimensions and location of a scene-change notch or cueing spot for actuating the printer light-change mechanism
2、when printing 35-mm, 16-mm, and 8-mm type S motion-picture films. (See annex A.1 for a frame- count cueing method which is more commonly utilized.) 1.2 Although this practice specifies a notch or a cueing spot for actuating the printer light mech- anism, at no time should a film contain both. 2 35-m

Annex A (informative) Cueing methods A.l Framecount cueing method A frame-count cueing device provides cue signals for auto- matic light changes, fades, and dissolves at
27、the appropriate frame without notching or placing cueing spots on the negatives. A preprogrammed memory device releases cue pulses at the correct frame location during the printing process. The scene length record may be in feet and frames or frames only as measured either from the start of the film
28、 to each successive cue (milestone methods) or from the preceding light change to the next scene (batch method). O A.2 Alternate method of notch cueing For forward and reverse printing, the same notch can be used. A second notch detector may be incorporated on the printer at any desirable distance f
29、rom the printing aperture normally placed on the opposite side of the printing aperture in the direction of reverse film travel. Time-delay memory devices are necessary to accommodate the travel time of the film so that the scene change takes place at the proper frameline position. A.3 Alternate mei
30、hod of spot cueing For forward and reverse printing, the same cueing spot can be used. A second cueing spot detector may be incor- porated on the printer at any desirable distance from the printing aperture normally placed on the opposite side of the printing aperture in the direction of reverse film travel. Time- delay memory devices are necessary to accommodate the travel time of the film so that the scene change takes place at the proper frameline position. Page 5 of 5 pages
