Glossary 417
decibel (dB) Unit of measurement for sound levels; a logarithmic scale used to
describe the loudness of sound as perceived by the human ear. (1 dB corresponds to
approximately the smallest volume change that the average human ear can perceive.)
For digital audio, dBFS is the standard decibel unit of sound level measurement. See
also digital full scale.
decompression The process of creating a viewable image for playback from a
compressed video, graphics, or audio file. Compare with compression.
desaturate To remove color from an image. 100 percent desaturation results in a
grayscale image.
destination track The track a particular source item is edited into in the Timeline, as
defined by the Source and Destination controls in the Timeline patch panel.
destination track controls Source and Destination controls in Timeline tracks that
allow you to specify which tracks source clip items are edited into in the Timeline.
device control Technology that allows Final Cut Pro to control an external hardware
device, such as a video deck or camera. Three protocols are used most frequently to
control video devices: serial device control via the RS-422 and RS-232 protocols, and
FireWire for DV camcorders and decks.
dialogue The recorded audio of one or more people speaking in a video clip. The
designated dialogue track in an editing project is likely to include most of the location
audio that was captured along with the video.
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 10-bit digital videotape recorder format with
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-S See D9.
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.
