■ GLOSSARY

digital signal vs. traditional analog. Often

confused with high-definition television

(HDTV).

dubbing In videotape production, the process

of copying video or audio from one tape to

another. In film production, the process of

replacing dialog on a sound, as in automated

dialog replacement (ADR) or foley recording.

Can also refer to foreign language transla-

tions on audio tracks.

dubmaster A second-generation copy of a pro-

gram master used for making additional copies

,

thereby protecting the master from use.

dupe A duplicate. When one or more frames

are used twice in an edited sequence. Short

for “duplicate,” as in duplicate frames. Dupe

lists are generated to determine which frames

will need to be duplicated before a list is con-

formed. The neg is copied onto an interposi-

tive, which is then duplicated. See also IP.

dupe reel A reel used for recording and play-

back of duplicate shots during videotape

editing. Dupe reels are used in linear edits, in

which a transition must occur from two dif-

ferent shots that occur on the same reel. One

of the shots is dubbed to the dupe reel.

duration The length of time (in hours, min-

utes, and seconds; or in feet and frames) that

a particular effect or section of audio or

video material lasts.

DV Acronym for digital video. Video that is

transferred through equipment conforming to

IEEE Standard 1394 or FireWire.

DVE Acronym for digital video effect. Usually

refers to a specific device that creates digital

video effects, such as Ampex ADO, Grass

Valley Kaleidoscope, and others. Originally

used as a trademarked name by NEC,

which introduced its DVE the same year

Ampex introduced its similar-in-function ADO.

dynamic range An audio term that refers to the

range between the softest and loudest levels

that a source can produce without encounter-

ing distortion. Also refers to the color depth

or possible pixel values for a digital image—

the number of possible colors or shades of

gray that can be included in a particular

image. Eight-bit images represent up to

256 colors; 24-bit images represent approxi-

mately 16 million colors.

edge code A broad classification of film frame

numeration that can be either key numbers

or ink numbers. Printed numbers on the edge

of film that identify frames; a method of

keeping track of edits through a simple num-

bering process. There are two types of edge

numbers. Acmade or ink numbers can be

printed on the edge of synced workprint and

mag track by an inkjet printer. Key numbers

(also called latent edge numbers) appear on

the edge of the film when it is developed.

Key numbers are more commonly used with

nonlinear editors (NLEs).

edge filter A filter that applies anti-aliasing to

graphics created in the Title tool, thus pre-

venting jaggies.

edit bench The place in which much of the

nondigital work takes place. Synchronizing

and conforming are done here. Also known

as the bench or workbench. Typically con-

tains rewinds, a gang sync, and a splicer.

edit controller An electronic device, usually

computer-based, that allows an editor to

precisely control playback, shuttling, and

recording to various videotape machines.
