GLOSSARY ■

aspect ratio The ratio of picture width to pic-

ture height. 1.85:1 is the most common film

aspect ratio in the United States; 1.66:1 is

more common in Europe. Standard-definition

television is 4:3. Most high-definition televi-

sion (HDTV) pictures are 16:9.

assemble list A cut list that includes all the

edits in a sequence in the order in which they

occur chronologically. Used for conforming

negative or work print. Also known as the

cut list.

ATM Acronym for Asynchronous Transfer

Mode. A network technology based on trans-

ferring data in small packets of a fixed size.

Used as a means to transmit video, audio,

and computer data over a network. Packet

delivery ensures that no stream of data will

tie up the line.

ATR Acronym for audiotape recorder.

ATSC Acronym for Advanced Television Stan-

dards Committee. The group that is develop-

ing standards for high-definition and digital

television as well as compression schemes

for broadcasting them. Currently, there are

18 different types of high-definition televi-

sion (HDTV).

Attic folder The folder containing backups of

bins. Everytime bins are saved by the user or

are autosaved by the Avid, copies of the bins

are placed in the Attic folder.

audio scrub The process of shuttling through

and monitoring segments of audio at various

speeds. Originates from earlier analog audio

days when audiotape media was “scrubbed”

against the play head of an ATR to monitor

cue points.

audio sweetening The mixing of sound effects,

music, and announcer audio tracks with the

audio track of the edited master tape, usually

during the mixing stages of a production.

audio timecode Longitudinal timecode (LTC)

recorded on track normally used for audio.

AutoSave A feature that saves your work at

intervals you specify using your Bin settings.

Backups are placed in the Attic folder.

autosync Feature that allows for synching and

combining of separate audio and picture clips

on an Avid nonlinear editor (NLE).

AUX Auxiliary source. Used normally in linear

video systems, AUX refers to an arbitrary

external video or audio source.

backtiming A method of calculating the in

point by subtracting the duration from a

known out point so that, for example, music

and video or film will end on the same note.

bandwidth Refers to the upper limit of data

that can be transferred within a single chan-

nel or medium.

batch capture An automated process in which

groups of clips, sequences, or both are

recorded digitally from source media.

batch digitize Same as batch capture.

batch list Import log format for Final Cut Pro.

A telecine log must be converted into a batch

list before it can be digitized into a Final Cut

Pro NLE. The equivalent of an ALE file for

Avid or Power Log file for Media 100.

Bézier A type of curve that you can use for

segments in some types of effects keyframes.

A Bézier point on a curve allows you to con-

trol the smoothness or sharpness of the

motion of the keyframe.

bin A container where film workprint is stored

hanging from pins. The editor’s completed

scenes are normally stored in a separate bin.
