1084 Glossary
digital A description of data that is stored or transmitted as a sequence of 1s and 0s.
Most commonly, refers to binary data represented using electronic or electromagnetic
signals. QuickTime movie files are digital. Compare with analog.
Digital-8 A standard definition consumer digital video format that records a DV video
signal onto Hi-8-style tapes.
Digital Betacam A standard definition digital videotape recorder format with
approximately 2:1 video data compression and 4:2:2 color sampling. Supports four
tracks of audio with 20-bit, 48 kHz audio sampling.
digital full scale The full audio signal range that can be recorded digitally without
distortion.
digital video Video that can be captured, manipulated, and stored using a digital
format, such as QuickTime. A digital video camcorder, for example, is a video camera
that records images digitally on a medium such as tape. Because the signal is digital, it
can be easily transferred to your computer.
digitize To convert an analog video signal into a digital video format. A method of
capturing video. See also capture.
disabled track A track that has had its Track visibility control disabled. Disabled tracks
will not output to tape or be rendered into a QuickTime file for output.
disclosure triangle A small triangle you click to show or hide details in the interface.
distort To change the shape of a clip by moving a corner point independently of the
other corner points. Also, to squeeze a clip horizontally or vertically to change the ratio
of its width to its height (the aspect ratio).
downmixing Also referred to as mixing down, the process used to combine multiple
audio channels to a single stereo (or dual mono) pair.
drop frame timecode NTSC timecode that skips ahead in time by two frame numbers
each minute, except every tenth minute, so that the timecode agrees with the actual
elapsed clock time. (Timecode numbers are skipped, but actual video frames are not
skipped.) This skipping corrects for NTSC’s actual frame rate of 29.97 fps. It corrects for
an inaccuracy of 3 seconds and 18 frames per hour in comparison to actual elapsed
time when non-drop frame timecode is used. To avoid confusion, dropframe timecode
should be avoided in film-based productions. Compare with non-drop frame timecode.
drop shadow An effect that creates an artificial shadow behind an image. Typically
used with graphics and text.
