sampling

The process during which analog audio is converted into digital information. The sampling rate of an audio stream specifies how many samples are captured. Higher sample rates are able to reproduce higher-pitched sounds. Examples: 44.1 Kbytes, 48 Kbytes. Greater bit depths during sampling increase the dynamic range (changes in volume) of the audio.



saturation

The purity (intensity) of color. As saturation is decreased, the color moves toward gray.



scale

An adjustable value that changes the overall size of a clip. The proportion of the image may or may not be maintained.



scrub

To move through a clip or sequence manually with the aid of the playhead. Scrubbing is used to find a particular point or frame or to hear the audio.



SECAM

(Sequential Couleur Avec Memoir) The French television standard for playback. As with PAL, the playback rate is 25 fps and the frame size is 720x546. Primarily a broadcast medium; editing for SECAM broadcasts is still performed in PAL.



Select/Transform tool

The default arrow-shaped pointer, which allows you to select items in the interface. For example, you use it to select a clip or edit point.



sequence

An edited assembly of video, audio, or graphics clips.



shot composition

See [framing]
Simulations behaviors

Advanced effects that incorporate laws of physics and geometry to achieve sophisticated movements and reactions. Motion includes a variety of Simulations behaviors, such as Gravity, Edge Collision, and Repel From.



SMPTE

(Society of Motion Picture and Television Engineers) The organization responsible for establishing various broadcast video standards, like the SMPTE standard timecode for video playback.



snapping

The process by which the playhead or an object in the Canvas "snaps," or jumps directly, to a guide, marker, or edit point when it is moved close to one.



solo

The process of temporarily disabling all objects other than the selected objects in order to improve real-time performance.



sound bite

A short excerpt taken from an interview clip.



spin

A camera shot in which an object rotates slowly as the camera gradually zooms closer.



square pixel

A pixel that has the same height as width. Computer monitors have square pixels, but NTSC and PAL video do not.



standard definition

The term used to differentiate traditional television broadcast signals from those of new high-definition formats. Standard- definition broadcast signals are usually 720x486 (for NTSC) or 720x576 (for PAL).

Status Bar

A display above the Canvas that you can turn on during the playback of a motion graphics project to show color, coordinates, and the frame rate.



stereo audio

Sound that is separated into two channels, one carrying the sounds for the right ear and one for the left ear. Stereo pairs are linked and are always edited together. Audio-level changes are automatically made to both channels at the same time.



straight cut

An edit in which both the video and audio tracks are cut together in the Timeline.



streaming

The delivery of media over an intranet or over the Internet.



super black

Black that is darker than the levels allowed by the CCIR 601 engineering standard for video. The CCIR 601 standard for black is 7.5 IRE in the United States and 0 IRE for PAL and NTSC in Japan.



super white

A value or degree of white that is brighter than the accepted normal value of 100 IRE allowed by the CCIR 601 standard.



superimpose

In Motion, to place an object above another file in the Timeline. Titles are usually superimposed on other objects or layers.
