GLOSSARY ■

NTSC Acronym for National Television Stan-

dards Committee. The group that developed

the standard for color television in the United

States. NTSC signals have 525 lines of verti-

cal resolution at a frame rate of 29.97 fps.

OCN Acronym for original camera negative.

See original camera negative (OCN).

offline Pertaining to items that are not cur-

rently recognized by the computer, such as

offline media files.

offline edit Usually refers to a rough or cre-

ative cutting of a sequence. Traditionally,

offline edits were assembled on simple non-

computerized video equipment, so these

sequences were literally offline and edited

without regard to broadcast standards. With

the advent of nonlinear systems, the line

between offline and online has been blurred

and defined only by resolution standards

and broadcast acceptance.

OMFI Acronym for Open Media Framework

Interchange. A file format that is used prima-

rily for transferring audio files (but is capable

of containing video files as well) and sequences

from one work station to another. Platform-

independent.

online edit Usually the final edit using the

master tapes and (sometimes but not always)

an edit decision list (EDL) to produce a

finished program ready for distribution or

broadcast. Usually associated with high-

quality computer editing and digital effects.

opticals The separate creation of dissolves,

fades, and superimpositions by an optical

house. A-roll conformed films must create

opticals of all such effects. A/B-roll con-

formed films must create opticals of any

effects that are not lab standard durations.

original camera negative (OCN) The original film

shot on location. Most films are shot with

negative (not reversal) film.

outtake A take that is not selected for inclu-

sion in the finished product. Frequently asso-

ciated with comedic production and

performance errors.

overwrite An edit in which existing video

and/or audio is replaced by new material.

oxide A metallic coating used for electronic

recording that is magnetized during the

recording process.

PAL Acronym for phase alternating line. A

standard that is used in many different

countries (as opposed to NTSC or SECAM).

Features 625 vertical lines of resolution and

a frame rate of 25 fps.

palette 1. A central location for color selec-

tion. 2. A central location for user-selectable

buttons, as in the Command palette.

pan and scan A method of transferring

widescreen images to standard-definition tel-

evision (SDTV), in which the telecine opera-

tor can zoom into a part of the widescreen

image and pan across it, filling the SDTV

screen but eliminating some elements of the

wider original picture. Pan and scan is a

time-consuming and expensive method of

transfer.

partition Dividing of hard disk space to create

two or more virtual drives on a single physi-

cal drive.

patching The routing of audio or video from

one channel or track in the sequence to

another. Traditionally from patch bays, in

which audio and video signals were routed

through cables and connectors.
