safe action area, safe title area An area in the center of the video image
considered safe to place a title or other graphic, or capturing movement, so
that none of it is cut off at the edges of the TV screen. The safe action area is
10% percent smaller than the maximum image size, and the safe title area is
20% smaller.
saturation 1. Saturation is the brilliance or purity of a given color. For
example, the difference between a pastel and a pure color is defined by the
amount of saturation. 2. The intensity of colors. 3. The degree by which the
eye perceives a color as departing from a gray or white scale of the same
brightness.
Schematic A view in which the artist builds a dependency graph for a
composition. See also dependency graph.
SECAM Séquentiel couleur à Mémoire. A color television standard developed
in France and used throughout Eastern Europe. The SECAM standard uses 625
lines per frame. See also NTSC, and PAL.
shader A program that defines the look of objects in a scene. Shaders are
part of the rendering pipeline.
sharpness Sharpness can be defined as the visual sense of the abruptness
of an edge. It highlights the detail in an image or image sequence.
SMPTE Society of Motion Picture and Television Engineers. A frame
numbering system used for electronic editing and timing of video productions.
Each frame of video is assigned a number. Timecode denotes the hours:
minutes: seconds: frames (00:00:00:00) elapsed on videotape. There are two
types of timecode: drop frame and non-drop frame.
softness Colors that fall within the softness range are partially transparent.
These areas appear gray (a dark gray to light gray range) in the matte. For
example, softness makes the transition between the foreground and
background of a composition more convincing by softening what would
otherwise look like an abrupt cutout. Softness can also be used to retain
transparent key-in materials or shadows that you want to appear in the result
composition.
stabilizing To remove motion jitter and unwanted camera movement from
a clip.
super tool A tool comprised of a set of tools that includes Reaction, Garbage
Mask, 2D Compositor, Image Import, Keyer, Tracker, and Paint.
surface A geometric object onto which a source is mapped to create a layer
for a composition. Geometric types include: bilinear, frustum, box, plane, and
sphere.
