■ GLOSSARY

specially equipped camera and a telecine

with metaspeed or other speed-alteration

device.

three-point editing The principle that any edit

requires only three marks between the source

and record sides to automatically calculate

the fourth mark and thus complete the edit.

three-stripe Magnetic film stock containing

three rows of magnetic oxide coating.

TIFF Acronym for Tag Image File Format. A

graphics format.

time-base error A variation in the stability of

picture information, color information, and

video sync pulse during playback on a video-

tape recorder (VTR).

timecode A numbering system used to meas-

ure frames of video. Non–drop frame is

most commonly used on film and has a

direct number to frame correspondence,

but is not completely time-accurate due to

the actual video rate of 29.97 fps (NTSC).

Drop frame does not have a direct frame-to-

frame numbering correspondence, but it is

time-accurate.

timecode reader A machine used in telecine

that reads timecode, usually connected to a

timecode character generator that can put

timecode burn-in windows onto a transferred

videotape.

timecode window Refers to character-gener-

ated timecode numbers superimposed on

video images for reference to timecode of a

master tape.

Timeline The graphical representation of edits

made to a sequence.

tone A constant audio frequency signal

recorded at the start of a tape at 0 VU (vol-

ume units) to provide a reference for later

use. Usually recorded in conjunction with

SMPTE color bars.

track A single channel of audio or video.

tracker In motion tracking, a structure associ-

ated with a specific region of interest that

contains a single set of data points.

tracking The adjustment of video heads dur-

ing playback of a tape to ensure the strongest

possible constant signal.

tracking edit A zero-duration edit used during

transition edits (dissolves, wipes, and so forth)

on computerized linear editing systems.

track selector An interface function of select-

ing an active track in the Timeline.

TransferManager The Avid application that

allows you to transfer media from one work-

group to another.

transition Any form of edit between two pic-

tures. Can be a cut, dissolve, or other repre-

sentation of what is to take place as one

segment ends and the next one begins.

transition effect An effect that can be applied

to an edit transition.

transition play loop The loop that plays in

Avid’s Trim mode, which allows the editor to

see slightly before and slightly after a transi-

tion. Plays in a continuous loop.

trichromatic Three-color, such as RGB.

trim The process of adjusting transitions in a

sequence. Used for fine-tuning and cleaning

up sequences.

24p 24-fps progressive frames. 24p frames

are created by deinterlacing two video fields

into a single full, reconstructed frame.

25p 25-fps progressive frames. 25p frames

are created by deinterlacing two video fields

into a single full, reconstructed frame.
