digital A signal that contains information in a

binary form. Digital signals are often per-

ceived incorrectly as being lossless. However,

some are compressed, others are not.

digital cut An output to videotape of your

project direct from a nonlinear editor (NLE).

digital encoding Referring to the transforma-

tion of any analog information into digital

values.

digital recording A method of recording in

which the recorded signal is encoded on the

tape as binary digits and then is decoded dur-

ing playback.

digitally record To convert analog video and

audio signals to digital signals.

digitize Also known as capture. To input

video and/or audio into a digital nonlinear

editor (NLE) format. The process of convert-

ing analog signals to digital values. In some

cases, a process of transferring digital values

from one storage medium to another. Can

also refer to any type of capture of media

into a digital format, such as scanning a

events (dissolves, effects, wipes, graphic over-

lays) that are performed at the end.

modern dongles are USB-based.

double-perf film Film stock with perforations

along both edges of the film.

double system Any film- or video-recording

system in which picture and sound are

recorded on separate media. A double system

requires the resyncing of picture and sound

during postproduction.

drop frame A timecode-counting method that

reflects real time. To compensate for the base

30 timecode count and the actual frame rate

of National Television Standards Committee

(NTSC) video (29.97 fps), drop-frame time-

code skips ahead two frames in the count at

the top of every minute, excepting the tenth

minutes of time. Does not exist in phase

alternating line (PAL) video.

drop shadow A shadow that is offset from a

title or shape and superimposed onto a

background to give the sense of spatial

dimension.
