Edge Numbers

Coded numbers printed along the edged of a strip of film for identification purposes.

Edge track

A standard position for the placement of the audio on a single perforation magnetic film.

Edison Plug

An ordinary household plug with two flat blades and a ground pin. (Lighting)

Edit Decision List (EDL)

The list of SMPTE codes, in footage and frames, and including instructions for fades, dissolves and other special effects which corresponds to all the segments that the editor of a film or videotape production has decided to use in the final cut.

Edit Master

Video industry term for the tape containing the finished (edited) program.

Edit Points

Also known as "edit in" and "edit out." The beginning and end points of an edit when a video program or soundtrack is being assembled.

Edit suite

Room where editing is done.

Editing

Production of finished videotape from source tape. Editing usually involves the use of a computer editing system to select scenes and audio from multiple video and audio sources and record them into a finished program on a single videotape.

Editor

An editing system operator. Also the informal term used for an edit controller.

Editor interface

A serial communications link between an edit controller and peripheral devices, such as a video switcher and tape machines. The editor interface allows the edit controller to send control commands to the peripherals and receive status reports from the peripherals.

EEPROM

Electrically erasable programmable read-only memory. A type of memory chip that can hold data even when power is removed. The memory can be erased electronically so that new data can be stored.

Effective Output Level

The microphone sensitivity rating defined as the ratio in dB of the power available relative to sound pressure. (Acoustics)

Emboss:

Pressing an image into paper so that it will create a raised relief.

Emulsion

The gelatine layer of photo-sensitive material in which the image is formed on film. (Film)

Emulsion:

Light sensitive coating found on printing plates and film.

Enhanced CD

any disc that includes both standard audio tracks and data; also known as Blue Book, Mixed Mode, CD-I, CD-G, CD+ and Enhanced CD, among others. Current uses include adding multimedia, web sites, mp3 & RealAudio files, photos & song lyrics.

Enhanced DVD

enhanced DVD -- A general term for a DVD-Video disc that also contains computer-readable material. The disc includes both the DVD-Video portion and a DVD-ROM data portion that is ignored by set-top DVD players. The enhanced features may include computer applications (PC- and/or Macintosh-specific, web pages, or dynamic links from the DVD playback to online web content. Also called hybrid DVD. See also Web DVD.

Envelope

The shape of the graph as amplitude is plotted against time. A sound's envelope includes its attack, decay, sustain and release (ADSR). (Sound)

Environmental Sound

General low level sound coming from the action of a film, which can either synchronous or nonsynchronous.

EPROM

Erasable programmable read-only memory. A type of memory chip that can hold data even when power is removed. The memory can be erased (usually by ultraviolet light exposure) so that new data can be stored.

EPS

Encapsulated PostScript is a file format that allows PostScript information to be stored within a file. The information can then be downloaded to a RIP without the need for PostScript processing.

Equalization

The alteration of sound frequencies for a specific purpose, such as to remove 'noise' frequencies or to improve speech clarity.

Equalization (EQ)

Process of altering the frequency response of a video amplifier to compensate for high-frequency losses in coaxial cable.

Equivalent Noise

A microphone in a completely silent room still generates some residual noise. This noise can be measured and can be computed. That computation is the 'Equivalent Noise'. (Acoustics)

Establishing Shot

Usually a long shot at the beginning of a scene which is intended to inform the audience about a changed locale or time for the scene which follows. (Production)

Eurobind:

A patented method of binding perfect bound books so they will open and lay flatter.

Exciter Lamp

An incandescent lamp used to supply nonvarying luminous energy to a photoresponsive cell. Used in film projectors to illuminate the optical sound track.
