Effects and transitions
Last updated 11/6/2011
Note: The anti-aliasing of the grid borders may cause the visible thickness to vary.
Feather The softness of the grid.
Invert Grid Inverts the transparent and opaque areas of the grid.
Color The color of the grid.
Opacity The opacity of the grid.
Blending Mode The blending mode to use to composite the grid on top of the original clip. The default None mode
renders the grid only.
Lens Flare effect
The Lens Flare effect simulates the refraction caused by shining a bright light into the camera lens.
Flare Center Specifies a location for the center of the flare.
Flare Brightness Specifies the percentage of brightness. Values can range from 0% to 300%.
Lens Type Selects the type of lens to simulate.
Blend With Original Specifies the degree to which the effect will be blended with the source clip.
Lightning effect
The Lightning effect creates lightning bolts, Jacob’s Ladders, and other electrical visuals between two specified points
in a clip. The Lightning effect is automatically animated without keyframes across the time range of the clip.
Start Point, End Point Where the lightning begins and ends.
Segments The number of segments that form the main lightning bolt. Higher values produce more detail but reduce
the smoothness of motion.
Amplitude The size of undulations in the lightning bolt as a percentage of the clip width.
Detail Level, Detail Amplitude How much detail is added to the lightning bolt and any branches. For Detail Level,
typical values range from 2 through 3. For Detail Amplitude, a typical value is 0.3. Higher values for either control are
best for still images but tend to obscure animation.
Branching The amount of branching (forking) that appears at the ends of bolt segments. A value of 0 produces no
branching; a value of 1.0 produces branching at every segment.
Rebranching The amount of branching from branches. Higher values produce tree-like lightning bolts.
Branch Angle The angle between a branch and the main lightning bolt.
Branch Seg. Length The length of each branch segment as a fraction of the average length of the segments in the
lightning bolt.
Branch Segments The maximum number of segments for each branch. To produce long branches, specify higher
values for both Branch Seg. Length and Branch Segments.
Branch Width The average width of each branch as a fraction of the width of the lightning bolt.
Speed How fast the lightning bolt undulates.
Stability How closely the lightning follows the line defined by the start and end points. Lower values keep the lightning
bolt close to the line; higher values create significant bouncing.
Fixed Endpoint Determines whether the end point of the lightning bolt remains fixed in place. If this control isn’t
selected, the end of the bolt undulates around the end point.
