CUTTING: It happens not infrequently that from 5,500 to 7,000 feet (or
even more, if the director is inclined to be wasteful) of negative
film is exposed, or used up, in taking the scenes intended for a
five-part (5,000-foot) "feature." In every case, a certain amount of
film in excess of what is actually needed is inevitably exposed in the
photographing of the complete picture. In the "cutting room" of the
studio the director "assembles" his picture--pieces together the
different scenes, sub-titles, and inserts, and "cuts" portions varying
from a few inches to many feet in length when such portions, if
retained, would be regarded as "padding," or superfluous footage.

DIAPHRAGM: A term applying to a portion of the camera apparatus, and
also applied to the process of causing one scene to disappear, or
another to appear. Like the "fade out" and "fade in," the "diaphragm
out" and "diaphragm in" are descriptive terms, but having a different
purpose. While the "fade out" or the "fade in" separate two parts of
a scene, and bring in between them the thing thought of or spoken of,
the "diaphragm out" and the "diaphragm in" (both usually placed in the
script on a separate line) serve the purpose of covering a supposed
lapse of time in the action, where a leader is not needed. (More fully
explained in text.)

DIRECTOR: Sometimes called the Producer. The man who plans and directs
the building and setting of all scenes in the production of the
picture, as well as casting the actors and actresses for the various
parts, pointing out, in a general way, what costuming and make-up are
required, and directing their acting and stage "business" during the
taking of scenes. "Producer" more properly is the term applied to the
manufacturer or manufacturing company.
