cut
The simplest type of transition, in which the last frame of one clip is followed by the first frame of the next.
D
D1
Stands for Digital 1, a digital video format that has a 4:3 frame aspect ratio and a 0.9:1 pixel aspect ratio. D1 pixels
are rectangular (non-square), unlike analog pixels, which are square. D1 is an international TV standard: D1-NTSC
uses a frame size of 720 x 486 pixels, and D1-PAL uses a frame size of 720 x 576 pixels. See also “
data rate
The amount of data moved over a period of time (for example, 10 MB per second). Often used to describe a
hard drive's ability to retrieve and deliver information.
decode
To divide an encoded video signal into its separate components. See also “
deinterlace
To remove artifacts that result from interlaced video. See also “
digital video
Video that consists of a binary signal, encoded as a series of zeroes and ones. All data that a computer
processes must be digital, so analog video must first be converted to digital video before it can be edited on a computer.
See also “
digitize
To convert analog video or audio to digital form.
dissolve
A fade from one clip into another.
dithering
Alternating the colors of adjacent pixels to approximate intermediate colors. (For example, displaying
adjacent blue and yellow pixels to approximate green.) Dithering enables monitors to approximate colors they are
unable to display.
Dolby Digital
Standard lossy audio format for DVD video. Supports mono and stereo audio, but is most commonly
used to compress 5.1 surround sound with the AC-3 codec. See also “
drop-frame
A timecode adjustment that drops certain frames to compensate for the uneven, 29.97 frames-per-second
format of color video. Drop-frame timecode is critical in broadcast applications. See also “
drop-out
An area of magnetic tape where information is missing. Drop-outs may occur due to dust, overuse, or
physical damage. They can cause random, flashing color pixels in affected frames. To avoid drop-outs, use a head-
cleaning tape regularly in your camcorder.
dropped frames
Missing frames lost during the process of digitizing or capturing video. Dropped frames can be
caused by a hard drive with a low data transfer rate.
DTV
Digital TV. Occasionally used to refer to desktop video.
DV
Generally refers to digital video, but also connotes the type of compression used by DV systems and formats. DV
also describes the tape cartridge used in DV camcorders and tape decks.
DV in
The DV input on a camcorder.
DV via USB
Capability that allows DV camcorders to transfer video using USB 2.0.
DV-to-AV converter
An electronic device that converts digital video signals into analog video signals. Compare to “
DVD
Abbreviation for digital video disc and digital versatile disc. DVDs look like CDs, but have a much larger storage
capacity—more than enough for a feature-length film compressed with MPEG-2. DVDs require special drives for
playback.
