Chapter 18 Glossary 537
compound clip You can use compound clips to group any combination of clips in
the Timeline or the Event 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. Eectively,
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 eects and transitions.
compression The process by which video, graphics, and audio les are reduced in
size. “Lossy” compression refers to a process of reducing video le sizes through the
removal of redundant or less noticeable image data. Lossless compression reduces le
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 are useful for cutaway shots, superimposed or composited images, and
sound eects. Connected clips remain attached and synchronized until you explicitly
move or remove them. A sequence of connected clips is a storyline.
contrast The dierence 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
“atter” look.
cross dissolve A common type of video transition, in which the rst 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 rst 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 eect.
This is the simplest type of edit.
cutaway shot A shot that is related to the current subject and occurs in the same time
frame (for example, an interviewer’s reaction to what is being said in an interview).
Often, a cutaway shot is used to eliminate an unwanted visual section of another shot.
The audio usually remains continuous during the cutaway, helping to make the edit
less noticeable.
Dashboard The Dashboard appears in the center of the toolbar and provides
a timecode display as well as icons showing audio levels and the status of
background tasks.
