H

HALATION. A defect of photographic films and plates. Light forming an image on the film is scattered by passing through the emulsion or by reflection at the emulsion or base surfaces. This scattered light causes a local fog which is especially noticeable around images of light sources or sharply defined highlight areas.

HARD. (1) As applied to a photographic emulsion or developer, having a high contrast. (2) As applied to the lighting of a set, specular or harsh, giving sharp dense shadows and glaring highlights.

HARRY. Trade name of a highly sophisticated and versatile digital effects system manufactured by Quantel. Incorporates Quantel's Paintbox digital effects generator.

I

IN THE CAN. Describes a scene or program which has been completed. Also, "that's a wrap."

INSERT EDIT. An electronic edit in which the existing control track is not replaced during the editing process. The new segment is inserted into program material already recorded on the video tape.

INTERLACE. The manner in which a television picture is composed, scanning alternate lines to produce one field, approximately every 1/60 of a second in NTSC. Two fields comprise one television frame. Therefore, the NTSC television frame rate of approximately 30 fps.

INTERMEDIATES. General term for color masters and dupes.

INTER-POSITIVE. A color master positive print.

J

JAM SYNC. Process of synchronizing a secondary time code generator with a selected master time code, i.e., synchronizing the smart slate and the audio time code to the same clock.

K

KEY NUMBER. See EDGE NUMBER.

KEYKODE NUMBERS READER. Device attached to a telecine or part of a bench logger which reads Keykode numbers bar code from motion picture film and provides electronic output to a decoder.

KINESCOPE. A film recording of a video image displayed on a specially designed television monitor. Also called "Kine." Only means of recording TV programs before video recorders and tape were invented.

L

LATENT IMAGE. The invisible image formed in a camera or printer by the action of light on a photographic emulsion.

LATITUDE. In a photographic process, the range of exposure over which substantially correct reproduction is obtained. When the process is represented by an H & D curve, the latitude is the projection on the exposure axis of that part of the curve which approximates a straight line with-in the tolerance permitted for the purpose at hand.

LAYBACK. Transferring the finished audio track back to the master video tape.

LEADER. Any film or strip of material used for threading a motion picture machine. Leader may consist of short lengths of blank film attached to the ends of a print to protect the print from damage during the threading of a projector, or it may be a long length of any kind of film which is used to establish the film path in a processing machine before the use of the machine for processing film.

LIQUID GATE. A printing system in which the original is immersed in a suitable liquid at the moment of exposure in order to reduce the effect of surface scratches and abrasions.

LOW KEY. A scene is reproduced in a low key if the tone range of the reproduction is largely in the high density portion of the H & D scale of the process.

LTC (Longitudinal Time Code). Time code recorded on one of the audio channels of video tape. Requires tape movement to read. (See also VITC.)

LUMINANCE. The monochrome (high resolution) portion of a video signal.

M

MATCH FRAME EDIT. An edit in which the source and record tapes pick up exactly where they left off. Often used to extend a previous edit. Also called a "tracking edit."

MATTE. An opaque outline which limits the exposed area of a picture, either as a cut.out object in front of the camera or as a silhouette on another strip of film.

MOS. Slang for silent shooting. From the slang German "mit out sprechen" ("without talking." The correct German phrase would be "ohne sprechen.")

MULTIPLEXER. Device or circuit used for mixing television signals to a single video recorder.
