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 end on the same note.

A duplicate copy of a file or disk in another location if the original file or disk becomes corrupted.

See also Avid Attic folder.

The difference between the upper and lower frequency limits of an audio sample component.

A pattern of vertical stripes of varying width and spacing that encodes information. Bar codes can be used to encode timecode on film.

The automated process in which groups of clips, sequences, or both are digitized (recorded digitally).

The automated process in which groups of clips, sequences, or both are recorded (recorded digitally).

The number of electrical oscillations that occur each second. Baud was the prevalent measure for bandwidth or data transmission capacity, but bps (bits per second) is used most often now and is more accurate.

A registered trademark of Apple Computer, Inc. A general container format and software API (application programming interface). Bento is used by OMFáInterchange as a storage and access system for the information in an OMFáInterchange file.

A telecine transfer performed with optimum settings of the color grade controls but without precise scene-by-scene color correction.

Trademarks of Sony Electronics, Inc. Two component videotape and video recording standards. Sony Betacam was the first high-end cassette-based system, recording video onto 1/2-inch magnetic tape. The SP version arrived 3áyears after the first Betacam, improving on signal-to-noise ratios, frequency responses, the number of audio channels, and the amount of tape available on cassettes. SP is now the only type sold.

A type of curve that you can use for curve segments on Intraframe shapes or in some kinds of graphs such as keyframe graphs. A BΘzier point on a curve allows you to control the smoothness or sharpness of the curve at the point.

A database in which master clips, subclips, effects, and sequences are organized for a project. Bins provide database functions to simplify organizing and manipulating material for recording, digitizing, and editing.

Video black, timecode, and control track that are prerecorded onto videotape stock. Tapes with black and code are referred to as striped or blacked tapes.

A video signal that has no luminance or chrominance components (except burst) but contains all the other elements of a video signal. Black burst is the reference signal commonly used for timing audio and video samples.

An electronic device that emits a signal that registers as pure black when recorded on videotape.

See black and code.

See setup.

The luminance value in a video image that you set to be equal to reference black when making a color adjustment.

Compare with white point.

A special effects procedure in which a subject is photographed in front of a uniformly illuminated blue or green background. A new background image can be substituted for the blue or green during the shoot or in postproduction through the use of chroma key.

A "checkerboard" or nonsequential method of assembly. In B-mode, the edit decision list (EDL) is arranged by source tape number. The edit system performs all edits from the tapes currently assigned to decks, leaving gaps that will be filled by material from subsequent reels.

See also A-mode, C-mode, D-mode, E-mode, source mode.

Bits per second. The standard measure of data transmission speeds.

An exact copy of the A-roll original material, or new original material on a separate reel, for use in A/B-roll editing.

See luminance.

The transfer of a program recorded on a lower quality videotape to a higher quality videotape (such as from 3/4-inch to 1-inch videotape, or from S-VHS to MII).

A visible timecode permanently superimposed (burned in) on footage, usually in the form of white numbers in a black rectangle. Burned-in timecode is normally used for tracking timecode during previews or offline editing. A videotape with burn-in is also called a burn-in dub or a window dub.

Black-Video-Black. A preview mode that displays black, newly inserted video, and then black again.

One of the color difference signals in the component color system of the NTSC video standard. The signal formula is:
