Glossary 415
chroma keying See blue or green screening.
clip An item in a Final Cut Pro project representing video, audio, or graphics media files
on disk.
clipping Distortion occurring during the playback or recording of digital audio
because of a signal that exceeds the maximum sample value of 0 dBFS.
CMYK Abbreviation for Cyan Magenta Yellow Black. The color space commonly used
for images that are printed with four-color ink on offset presses.
codec Short for compressor/decompressor, or encode/decode. A software component
used to translate video or audio from its analog uncompressed form to the digital
compressed form in which it is stored on a computer’s hard disk. DV, Photo, JPEG, and
Sorenson Video are common QuickTime video codecs. Also referred to as a compressor.
color balance Refers to the mixes of red, green, and blue in a clip. In Final Cut Pro, you
can adjust the color balance of the highlights (bright areas), midtones, or shadows
(dark areas) of your clip using the Color Corrector 3-way filter.
color bars A standard color test signal displayed as columns, often accompanied by a
reference audio tone. Color bars are used to adjust the video signal of the incoming
source tape to maintain proper color from tape to computer and through to output.
Color bars are also output to a master tape so that accurate duplicates (dubs) of the
tape can be made.
color correction A process in which the color of clips used in an edited program is
evened out so that all shots in a given scene match. Color correction is generally one of
the last steps in finishing an edited program. The color correction tools in Final Cut Pro
give you precise control over the look of every clip in your project by adjusting the
color balance, black levels, mids, and white levels of individual clips.
color depth The possible range of colors that can be used in a movie or image. There
are generally four choices with computer graphics— 8-bit (grayscale), 16-bit, and 24-bit
(millions of colors). Higher color depths provide a wider range of colors but require
more space for a given image size. Broadcast video is generally 24-bit, with 8 bits of
color information per channel. See also channels.
colorist A professional who performs color correction. The colorist, in consultation with
the cinematographer, director, or producer, works shot by shot to determine the look of
each clip according to the needs of the project.
component video A type of analog video signal in which the luma and chroma signals
are recorded separately for better video quality. Professional video equipment, such as
a Betacam SP deck, uses component Y´C
R

B
(also called component YUV) video inputs
and outputs. Another form of component video, component RGB, is not as widespread
on video gear as component Y´C
