cut The simplest type of transition, in which the last frame of one clip is followed by the first frame of the next.

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

“digital video” on

page 301 and “square-pixel footage” on page 307.

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 “encode” on page 302.

deinterlace To remove artifacts that result from interlaced video. See also “interlacing” on page 303.

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.

“analog video” on page 299, “AV-to-DV converter” on page 299, and “DV-to-AV converter” on page 301.

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

“lossy” on page 304.

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

“non-drop-frame” on

page 305 and “dropped frames” on page 301.

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 “AV-

to-DV converter” on page 299.

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.
