- Dashboard
An interactive floating window in which you can modify object parameters while you continue to create your composite. Dashboard controls include check boxes, color wells, sliders, and knobs.
- data rate
The speed at which data can be transferred, often described in megabits per second (Mbps). The higher a video file's data rate, the higher quality it will be, but it will require more system resources (processor speed, hard disk space, and performance). Some codecs allow you to specify a maximum data rate for a movie during render.
- decibel
(dB) A unit of measure for the loudness of audio.
- 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 a clip. Desaturation of 100 percent results in a grayscale image.
- digital
Describes data that is stored or transmitted as a sequence of 1s and 0s.
- digital video
Video that has been captured, manipulated, and stored using a digital format, which can be easily imported into your computer. Digital video can come in many different formats, such as Digital-8, DVCPRO, DVCAM, or DV.
- dissolve
A transition between two video clips in which the second one fades up over the top of the first one, eventually obscuring it.
- Dock
The strip on the Macintosh Desktop where you can store alias icons of the programs you use most frequently.
- drop-frame timecode
NTSC timecode that skips ahead in time by two frame numbers each minute, except for minutes ending in 0, so that the end timecode total agrees with the actual elapsed clock time. Although timecode numbers are skipped, actual video frames are not skipped. - See also [timecode]
- drop shadow
An effect that creates a shadow behind an image or text.
- dub
To copy an analog tape to the same type of format.
- duration
The length of a clip or a sequence from its In point to its Out point, or the length of time it takes that piece of video to play.
- DV
(digital video) A digital standard created by a consortium of camcorder vendors, which uses Motion JPEG video at a 720x480 resolution at 29.97 frames per second, stored at a bit rate of 5 Mbps at a compression of 4:1:1. This format does not provide timecode capabilities or an audio track for the cue channel.
- DVCAM
A standard-definition digital videotape recorder format that records an 8-bit, 5:1 compressed component video signal with 4:1:1 color sampling. Recorded using quarter-inch tape. Supports two tracks of audio with 16-bit, 48 kHz audio sampling, or four tracks of audio with 12-bit, 48 kHz audio sampling.
- DVCPRO
Panasonic's native DV (digital video) component format that records an 8-bit, 5:1 compressed component video signal using 4:1:1 color sampling (PAL uses 4:2:0). This format supports two tracks of audio with 16-bit, 48 kHz audio sampling, or four tracks of audio with 12-bit, 48 kHz audio sampling. DVCPRO adds a longitudinal analog audio cue track and a control track to improve editing performance and user-friendliness in linear editing operations.
- DVD
A disc that is the size of a CD but uses higher-density storage methods to significantly increase its capacity. Usually used for video distribution, DVD-ROM discs can also be used to store computer data.
- Dynamic Guides
A set of yellow lines that appear as you drag an object over the Canvas, to assist in aligning the object within the frame or to another object.
- dynamic range
The difference, in decibels, between the loudest and softest parts of a recording.
