Variable Linear Blur filter allows you to control
the effect power within the frame. You could have the effect appear
only at some image side rather than over the entire image.
Parameters:
Blur
Type
"Constant"
mode
represents the real motion blur effect while "Soft" adds subtle
directional blur. One-Way variations add not only motion blur, but a
visual motion also.
Size
Controls
the
blur
power. Value of 1.0 sets the maximum blur, but you can enter
in edit field values from -4.0 to 4.0 and get more blur, but with
a slightly reduced quality. Negative values set opposite-direction blur
for One-Way modes.
Area
Controls
how
large the soft area is. 0.0-none, 1.0-whole image. By keyframing
the Area control, you can wash the blur effect across the screen.
Direction
Controls
the
blur direction. Value of 1.0 = one full rotation (360
degrees). You can enter values up to 100.0 and create direction
animations (rotating direction).
Side
Controls
the
position of the effect area. 0.0-left, 0.25-top, 0.5-right,
0.75-bottom. You can enter values up to 100.0 and create side
animations.
Distribution
Higher
values
soften the boundary of the effect mask.
