even scanning lines of the picture. In NTSC 262.5 horizontal lines at 59.94 Hz. In PAL 312.5 lines at 50 Hz.
After the key light (primary light) is set, a fill light softens the shadows created by the key light.
Projectors, multiplexors and cameras, used to transfer film to
A measurement of the magnification of a lens indicated in
millimeters. A zoom lens has a variable focal length which allows the camera to film closer or farther from the subject without moving the camera or subject. A 9mm – 100mm lens can makes its widest shot at 9mm, its closest at 100mm.
Personal sound effects, like footsteps, breathing or punches used to heighten realism.
Describes the video equipment and tape used. Popular formats
listed in ascending order of cost and quality include VHS, SVHS, and Betacam.
A complete television picture made up of two fields, produced at the rate of 29.97 Hz (color NTSC), or 30 Hz (black & white NTSC).
A digital device designed to store and display a single frame of video as a freeze frame. (See also Still Store.)
Digital device which synchronizes two or more video signals. The frame synchronizer uses one of its inputs as a reference and genlocks the other video signals to the reference’s sync and color burst signals. By delaying the other signals so that each line and field starts at the same time, two or more video images can be blended, wiped and otherwise processed together. (A Time Base Corrector takes this a step further by synchronizing both signals to a stable reference, eliminating time base errors from both sources.)
The technician responsible for placing, rigging and adjusting
Similar to duct tape, but vastly superior. Used extensively in
film and video production.
Created when editing or copying one analog videotape to another
videotape. Most apparent in less expensive video formats. Theoretically absent from digital video editing.

replaced during the editing process. The new segment is inserted onto a prerecorded black video tape. See also Assembly Edit.
A close-up shot used to hide an edit or to emphasize a detail.
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 resulting in the NTSC television frame rate of approximately 30 fps.
IN THE CAN
Same as “that’s a wrap” to indicate that the scene or program
which has been completed.
A jarring edit caused by the choice of shots rather than any
The primary light used to illuminate a subject.
Also called a “hair light.” Placed behind the subject to
create a glamorous halo effect on the hair or a rugged-looking highlight on the cheek. Helps separate the subject from the background.
Process of synchronizing a secondary time code generator with a
selected master time code, e.g., using the time code generated by one camera to insert the identical time code on a second camera.
Also called “Kine.” A method of making a film copy of a television program in the days before the existence of Video Recorders. A movie camera was aimed at a specially designed television monitor. Before video recorders were invented this was the only means of recording TV programs. Many kinescopes are now over 40 years old and have the potential to outlast videotapes that were created much later.
A small microphone that is clipped to a person’s clothing.

to a single video recorder.
MATCH FRAME EDIT
An edit in which the source and record tapes pick up exactly
where they left off. Often used to extend or correct a previous edit. Also called a “frame cut.”
“Mit Out Sound” a slang term for silent shooting actually
from the German “mit out sprechen” (without talking).
A video display similar to a TV, but having superior visual quality and without a tuner. An audio monitor is a speaker.
N.T.S.C. National Television Standards Committee created this first international television system for use in the U.S. and other countries. It produces pictures by creating 525 alternating lines across the TV screen for each frame of video. Since PAL and SECAM, the other two world systems, were developed later, they took advantage of better technology. Insiders joke that NTSC means “Never The Same Color.”
One billionth of a second. An indication of the precision
required in the timing of video signals.
A type of SMPTE time code that continuously counts a full 30
frames per second. As a result, non-drop-fame time code does not exactly match real time. See also DROP FRAME.
The creative editing process which uses copies of the
camera tapes on a typically “cuts only” inexpensive editing system. All creative decisions and approvals are made during this process.
The final technical editing process which uses the original
camera tapes to repeat all decisions made in the offline editing process. Online editing uses a more sophisticated and expensive editing system capable of transitions like dissolves and wipes.

copies of the original camera tapes.
The complete editing process.
Processing amplifier that changes the video chroma and luminance signals feed through it. Also provides stable horizontal and vertical synch pulses.
The vital phase of production in which the script, budget,
locations, actors and props are planned.
5 to 7 seconds of camera running time before a shot can be used. In editing, this refers to a similar amount of automatic backspacing the edit decks perform to insure a stable edit.
The actual filming and creation of the raw elements as required by the script.
A high quality copy of the master tape. Inexpensive insurance in the event that the master is lost or damaged.
Trade name of a computer graphics system manufactured by Quantel. Used to create two-dimensional graphics, transform objects and change colors. The computer graphics generator for Quantel’s Harry system.

selected inputs to be combined, manipulated and sent
out on the program line or edit VCR.
T.B.C. (TIME BASE CORRECTOR)
A device to correct timing errors which can cause unstable edits. These errors are caused by the slight mechanical defects inherent in the playback of video tape machines. Essential for online editing and duplication. This device can “clean up” a consumer VHS video so that it meets F.C.C. “broadcast quality” standards.
An individual shot. When time and budgets permit, many takes may be filmed of the same shot.
