source footage Raw, unedited video that has been recorded by a camera.
spatial compression A compression method that reduces the data contained within a single video frame by identifying
areas of similar color and eliminating the redundancy. See also
codec .
splitscreen A special effect that displays two or more scenes simultaneously on different parts of the screen.
square-pixel footage Footage that has a 1:1 pixel aspect ratio, typically analog video. Most computer graphics have a
1:1 pixel aspect ratio. See also
D1 .
still frame A single frame of video repeated so it appears to have no motion.
storyboard A series of images representing each clip in a movie. You rearrange the images to change the order in which
clips appear. In Adobe Premiere Elements, storyboard-style editing occurs in the Sceneline. (See
Sceneline overview .)
straight cut The most common edit; consecutive clips placed one after another in the Timeline window. Straight cuts
are preferable to transitions when the scenes are similar and you don’t want edits to be noticeable.
streaming The process of playing video from the web as it is received, rather than waiting for an entire file to download
prior to playback.
striping Preparing a tape for editing by recording a video signal (for example, black) with a control track and timecode
to ensure proper playback. Also known as black stripe.
superimposing Combining images, where one or more layers involve transparency. See also compositing .
S-Video Super-Video. A technology used to transmit video by dividing the video information into two separate signals:
one for luminance (brightness) and one for chrominance (color).
temporal compression A compression method that identifies similar areas across video frames and eliminates the
redundancy. See also
codec .
timecode A time format that measures video in hours, minutes, seconds, and frames (for example, 1:20:24:09),
enabling precise editing. See also
drop-frame and non-drop-frame .
timeline The graphical element in a video-editing program on which video, audio, and graphics clips are arranged. (See
also
mini-timeline .)
transcoding Translating a file from one file format into another; that is, reencoding the data.
transforming Changing the position of objects (for example, text or graphics) by moving, rotating, aligning, or
distributing them.
transition A change in video from one clip to another. Often these visual changes involve effects in which elements of
one clip are blended with another.
transparency Percentage of opacity of a video clip or element.
trimming Removing frames from the beginning, middle, or end of a clip.
tweening A feature that fills in the frames between two images so movement appears smoother. See also keyframes .
uncompressed video Raw digitized video displayed or stored in its native size.
USB Universal Serial Bus. The interface standard that allows a plug-and-play experience, where you can add a new
device to your computer without having to install an adapter card or configuring other elements. See also
IEEE 1394 .
vertex shader In 3D graphics, a program that a GPU uses to render effects realistically, relative to an object’s position
in space. (Not all GPUs support vertex shaders.) Vertex shaders are commonly used in creating graphics for computer
games.
