sliders (right). The Other Options button and the Color Preview window are highlighted in each example.
Common 2D Effect Parameters
This section describes, in alphabetical order, 2D effect parameters that are common to multiple
effects across at least two effect categories.
Acceleration
Acceleration adjusts the speed of an effect over time by having the effect ease in and ease out of
every keyframe. This gives the effect a more natural appearance. This parameter is not
keyframeable.
The overall speed of an effect depends on its duration, which in turn depends on the length of the clip
in the sequence. To slow down or speed up the movement of an effect, change the length of the clip or
use add edits to limit the portion of the clip affected by the effect.
Parameter Description
Other Options button Opens the Windows Color dialog box or the Macintosh Colors panel for precise color
selection. For more information, see “Adjusting a Color Parameter for an Effect” on
page 74.
Color Preview
window
Displays the currently selected color, and provides access to the eyedropper tool for
selecting a color from an image. For more information, see “Adjusting a Color Parameter
for an Effect” on page 74.
Hue Identifies the hue or tint of the color. Hue is measured as values on a color wheel ranging
from 0 to 255. The start (0) and end (255) values are both red.
Sat (saturation) Specifies the amount or intensity of the color. Values range from 0 to 255, where 0 is no
chrominance and 255 is a fully saturated color.
Lum (luminance) Specifies the brightness of the color. Values range from 0 to 255, where 0 is black and 255
is full brightness or white.
R (red) Specifies the red component of an RGB color definition. Values range from 0 (no red) to
255 (maximum amount of red).
G (green) Specifies the green component of an RGB color definition. Values range from 0 (no green)
to 255 (maximum amount of green).
B (blue) Specifies the blue component of an RGB color definition. Values range from 0 (no blue) to
255 (maximum amount of blue).
