Y. “A” AND “B” ROLLS (Continued from Page 499) practice and ingenuity, the 16mm film editor can “A” and “B” many clever effects. Sometimes “C,” “D” and “E’ rolls are also assembled to achieve almost unlimited multiple exposures or “mon¬ tage” sequences. Opening titles, for in¬ stance, can each be dissolved “A” to “B" while action background scenes are simultaneously dissolving on “C and D” rolls. Recently, a unique editing and print¬ ing procedure has been developed that, for the first time, permits camera nega¬ tive 16mm scenes to be printed with dis¬ solves, fades and superimposed titles. With this ingenious method, black and white release prints from camera nega¬ tives can be dressed up with effects pre¬ viously only possible by first filming on reversal original film, then printing the effects into a duplicate negative from which the second generation release prints were made. A clear understanding of the various “A and B roll” procedures enables the 16mm editor and producer to avoid the limiting camera-dissolves and camera fades, thus assuring the uniformity and versatility of scene transitions. Figure 3 also illustrates standardized procedure of labeling and preparing 16mm film leaders, locating sync marks, etc. Abridged from “How To Edit 16mm ‘A’ and ‘B’ Rolls,” by Edward Pyle, Jr., April, 1950, American Cinematographer.
