The Lens Flare effect has the following settings:
Brightness Specifies the percentage of brightness. Values can range from 10% to 300%.
Flare Center Specifies a location for the center of the flare.
Lens Type Selects the type of lens to simulate.
Lightning effect
The Lightning effect creates lightning bolts and other electrical effects, including a Jacob's Ladder appearance (as
seen in old horror movies) between two specified points in a clip image. The Lightning effect is automatically
animated without keyframes across the clip’s time range.
The Lightning effect has the following settings:
Start Point, End Point Specify where the lightning begins and ends.
Segments Specifies the number of segments that form the main lightning bolt. Higher values produce more detail
but reduce the smoothness of motion.
Amplitude Specifies the size of undulations in the lightning bolt as a percentage of the clip’s width.
Detail Level, Detail Amplitude Specify how much detail is added to the lightning bolt and any branches. For Detail
Level, typical values are between 2 and 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 Specifies the amount of 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 Specifies the amount of branching from branches. Higher values produce tree-like lightning bolts.
Branch Angle Specifies the size of the angle between a branch and the main lightning bolt.
Branch Seg. Length Specifies the length of each branch segment as a fraction of the average length of the segments
in the lightning bolt.
Branch Segments Specifies the maximum number of segments for each branch. To produce long branches, specify
higher values for both the branch segment length and the branch segments.
Branch Width Specifies the average width of each branch as a fraction of the width of the lightning bolt.
Adjust the following controls for the Lightning effect:
Speed Specifies how fast the lightning bolt undulates.
Stability Determines how closely the lightning undulates along the line defined by the start and end points. Lower
values keep the lightning bolt close to the line; higher values create significant bouncing. Use Stability with Pull Force
to simulate a Jacob’s Ladder effect and cause the lightning bolt to snap back to a position along the start line after it
has been pulled in the Pull Force direction. A Stability value that is too low does not allow the lightning to be
stretched into an arc before it snaps back; a value that is too high lets the lightning bolt bounce around.
Fixed Endpoint Determines whether the end point of the lightning bolt remains fixed in place. If this control is not
selected, the end of the bolt undulates around the end point.
Width, Width Variation Specify the width of the main lightning bolt and how much the width of different segments
can vary. Width changes are randomized. A value of 0 produces no width changes; a value of 1 produces the
maximum width changes.
