ADOBE PREMIERE PRO CS3 331 User Guide Flare Brightness Specifies the percentage of brightness. Values can range from 10% 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 and other electrical visuals, including a Jacob's Ladder result (as seen in old horror movies) between two specified points in a clip. The Lightning effect is automatically animated without keyframes across the clip's time range. 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 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 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. 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 doesn't 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 isn't selected, the end of the bolt undulates around the end point. Width, Width Variation 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. Core Width The width of the inner glow, as specified by the Inside Color value. Core Width is relative to the total width of the lightning bolt. Outside Color, Inside Color The colors used for the lightning bolt's outer and inner glows. Because the Lightning effect adds these colors on top of existing colors in the composition, primary colors often produce the best results. April 1, 2008
