We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
332 X. EDITING AND ASSEMBLY
cally copied on the work print when it is made. The identification characters should be easy to read and to interpret ; if possible they should be legible to the unaided eye. The identification markings are customarily placed along the perforated edge of the single-perforated film, or along the similar edge of the double-perforated film. The most usual form of identification is edge-numbering.
To facilitate the editing of the picture, it is possible to ' ' footage-number" in the sound track area of a single-perforated film; such markings can be copied on a work print by printing through the sound aperture of a printer. When release prints are to be made from the edited original, no change in procedure is required, since the footage markings appearing in the sound track area are merely ignored. It is apparent that this marking suggestion will function only if single-perforated film is used in the photographing camera, and if no sound is to be recorded on the photographing film.
Edge Numbering
There are two ways to obtain edge-numbered film for an original: (1) to purchase raw stock from the film manufacturer so marked, and (2) to have the film laboratory edge-number the original by running it through an edge-numbering machine before a work print is made. In both cases the edge-numbers are then printed from the original to the work print.
Edge-numbering* requires consecutive numeral markings at each foot along the film. Since there are 40 frames per foot, this interval may be too long without interim indentification ; such interim identification may be accomplished at 10-frame intervals with suitable marks such as a line, an asterisk, a carat, or other index. It is customary to keep records of editing in terms of feet and frames. If the same person who photographs the film edits it, identification and record keeping can be simpler than in the more usual case in which a different person does the editing.
Edge-numbered raw stock is not bought over the counter; it must be ordered in advance. Although film manufacturers customarily edgenumber film (when ordered) without extra charge, the numbering operation is an additional and special one that is accomplished after the film has been manufactured but before it is packed and marked for shipment. The order placed with the film supplier customarily specifies the emulsion type desired, the sizes and the mounting of the film rolls, whether the
* Some persons interested in 35-mm optical reduction prefer edge-numbering in intervals of 16 frames (16 frames equals 1 foot in 35-mm film).
