Glossary 411
ambience A type of sound. Ambient audio includes background room noise, traffic
noise, and atmospheric sound effects.
analog A signal that consists of a constantly varying voltage level, called a waveform,
that represents video and audio information. Analog signals must be digitized, or
captured, for use by Final Cut Pro. VHS and Betacam SP are both analog tape formats.
Compare with digital.
anamorphic Visuals that are shot in a widescreen format and then squeezed into a
4:3 frame size. This can be done by using a video camera’s electronics or, optically, by
using an anamorphic lens.
anchor item When you first link multiple audio clip items to a video item in the
Timeline, that video item is considered the “anchor” item to which the sync of all other
linked audio items is compared. If you’re linking a group of audio items without a video
item, the topmost audio item that appears in the Timeline acts as the anchor item.
anchor point In the Motion tab, the point that is used to center changes to a clip’s
geometry when using motion effects. Any changes to the size, position, and rotation of
a clip happen relative to this anchor point. A clip’s anchor point does not have to be at
its center.
Angle control A control used to rotate a clip around its center axis without changing
its shape. Located in the Motion tab of the Viewer. In the Angle control, the black hand
indicates the current angle of the clip, and the small red hand indicates how many total
rotations forward or backward have been specified.
A-only edit An edit of the audio files or video files of the base track only.
A-roll edit An edit of clips that contain audio data from the base track or a narration.
aspect ratio A film or video frame’s width-to-height ratio on any viewing screen. The
most common aspect ratio is 4:3, used for regular television screens. An aspect ratio of
16:9 is increasingly used for high definition video.
assemble edit mode In linear systems, assemble edit mode lays down new video,
audio, and control tracks all at once. It usually requires anywhere from 3 to 5 seconds of
pre-roll before you edit to tape. In Final Cut Pro, assemble edit mode is a function that
writes the sequence or clip to tape at the designated In point, or at the current point.
Assemble edit mode usually breaks the timecode and control track at the end of the
edit.
attenuate To lower an audio signal’s level.
audio channel indicator An icon in the Edit to Tape window that indicates which
audio tracks are being output.
