This matter of footage is one which demands the attention of both director and cameraman.  On the side of the motion-picture camera is an indicator, by which is computed the exact number of feet exposed each time the cameraman turns the handle.  At the conclusion of each scene the director cries “Cut!” The cameraman stops turning, looks at the indicator, and announces “Seventy-five!” or whatever the number of feet used.  In some cases it is necessary to take the scene again, altering the “business” slightly or hurrying the action a little to reduce the footage consumed in a certain scene.  A point worth noting is that the director can seldom figure in advance the exact amount of footage a certain scene will require—­even after it has been rehearsed and timed several times; whereas he can always tell the exact number of feet he must give to each of the various inserts, because “insert footage” is reckoned in advance, a certain number of feet being allowed for each word.

Photoplay audiences have gradually been educated up to an appreciation of sub-titles, or leaders, when they are all that they ought to be (a point which we shall presently discuss); and less attention is paid to the rather selfish cry of the illiterates in the audience who insist that “they came to look at pictures, and not to read a book.”  As one of the most prominent theatre managers in San Francisco recently said in the Motion Picture News:  “In many pictures the big scene is ’put over’ by a sub-title.  The wording of a sub-title in a big situation can make or break a picture, and it is therefore false economy to allow this work to be done by any person other than one with real literary talent, who is thoroughly conversant with the art of expression.”

We have already pointed out that in most studios the work of writing leaders and inserts is now attended to by one specialist—­the “sub-title editor,” as he is usually called.  Just as much care is put into the preparation of everything in the nature of an insert as attends the making of the scenes of the picture.

1.  Why Inserts Are Used

Before the advent of pictures of five and more reels, with their consequent greater room for inserted matter in addition to the necessary scenes, the general opinion was that the perfect photoplay had no leaders and needed none.  Certainly, such a picture would be ideal if a photoplay were to be a motion picture and nothing more than that, since it would be so perfectly acted and so self-explanatory that no inserted explanation of any kind would be necessary.  Practically, however, the only photoplay that can be made without the aid of at least a few leaders or other inserts—­that is, that can be nothing but pictured action—­is one on the order of the Vitagraph Company’s one-reel release of several years ago, “Jealousy,” in which the entire picture was made in a single set.  In it Miss Florence Turner was the only actor, telling
