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 allowing you to adjust the color
balance, black levels, midtones, and white levels of individual clips.
color difference In video formats that store color information in the Y'CbCr color space,
color channels are derived by subtracting Y (luma) from the R (red) and B (blue) signals
and are sometimes referred to generally as B-Y and R-Y. See also Y'CbCr.
Color inspector You use the Color inspector to perform manual color corrections using the
four color correction effects: Color Board, Color Wheels, Color Curves, and Hue/Saturation
Curves.
compositing A process in which two or more images are combined into a single frame.
This term can also describe the process of creating various video effects.
compound clip You can use compound clips to group any combination of clips in the
timeline or the browser and nest clips within other clips. You can open any compound clip,
edit its contents in the timeline, and then close it. Compound clips can contain video and
audio clip components, clips, and other compound clips. Effectively, each compound clip
can be considered a mini project, with its own distinct project settings. Compound clips
function just like other clips: You can add them to your project, trim them, retime them, and
add effects and transitions.
compression The process by which video, graphics, and audio files are reduced in size.
“Lossy” compression refers to a process of reducing video file sizes through the removal
of redundant or less noticeable image data. Lossless compression reduces file sizes by
mathematically consolidating redundant image data without discarding it.
connected clip Connected clips are attached to clips in the primary storyline in the
timeline. They’re useful for cutaway shots, superimposed or composited images, and
sound effects. Connected clips remain attached and synced until you explicitly move or
remove them. A sequence of connected clips is a storyline. See also cutaway shot.
contrast The difference between the lightest and darkest values in an image. High-
contrast images have a large range of values from the darkest shadow to the lightest
highlight. Low-contrast images have a more narrow range of values, resulting in a
“flatter” look.
corner point A point with no curves applied in a Bezier path. Adjacent line segments are
linear. See also Bezier curve.
cross dissolve A common type of video transition, in which the first shot fades out while
the second shot simultaneously fades in. During the cross dissolve, the two shots are
superimposed as they fade.
crossfade A common type of audio transition, in which the first shot’s audio fades down
while the second shot’s audio simultaneously fades up. During the crossfade, audio from
both shots is heard.
cut An edit in which one clip immediately follows another, with no transition effect. This is
the simplest type of edit.
