S_DissolveLensFlareTransitions between two input clips using an animated lens flare. The clips dissolve into each other, while a lens flare moves along a straight line. The lens flare grows and shrinks over the duration of the effect. The Dissolve Amount parameter should be animated to control the transition speed.In the Sapphire Transitions category.

Parameters:
-
Load Preset:
Push-button
.
Brings up the Preset Browser to browse all available presets for this effect.
-
Save Preset:
Push-button
.
Brings up the Preset Save dialog to save a preset for this effect.
-
Dissolve Amount:
Default:
0,
Range:
0 to 1.
The transition ratio between the From and To inputs. A value of 0 gives only the From input and a value of 1 gives only the To input. By default this parameter automatically animates from 0 to 1 to perform a complete transition. The curve controlling this parameter can be adjusted for more detailed control over the timing of the dissolve. In the AVX1 version, Auto Trans must be disabled for this parameter to be used.
-
Dissolve Speed:
Default:
3,
Range:
1 or greater.
The speed of the dissolve between the From and To clips. When set to 1, the dissolve takes place over the entire duration of the effect. When set higher, the dissolve is shorter, although the lens flare still changes size and brightness over the entire duration. Setting this to 10 can make the transition snappier and more like a flash-frame cut.
-
Hotspot Center:
X & Y, Default:
screen lower left.
The location through which the brightest spot of the flare passes at the center of the transition.
-
Hotspot Speed:
Default:
1,
Range:
0 to 2.
The speed at which the flare sweeps across the screen. Set this to zero to make the lens flare grow and shrink in place.
-
Hotspot Angle:
Default:
-25,
Range:
any.
The angle at which the flare sweeps across the screen.
-
Pivot:
X & Y, Default:
screen center.
The elements of the flare will be in a line between the Hotspot and the Pivot locations. The Pivot is in screen coordinates relative to the center of the frame.
-
Flare Brightness:
Default:
8,
Range:
0 or greater.
The maximum brightness of the flare at the center of the transition.
-
Flare Fade:
Default:
1,
Range:
0 to 1.
The fraction by which the brightness is reduced at the beginning and end of the transition.
-
Flare Width:
Default:
2.5,
Range:
0 or greater.
The maximum width of the flare at the center of the transition.
-
Flare Shrink:
Default:
0.5,
Range:
0 to 1.
The fraction by which the flare width is reduced at the beginning and end of the transition.
-
Rel Heights:
Default:
1,
Range:
0 or greater.
Scales the vertical dimension of all the flare elements, making them elliptical instead of circular.
-
Lens:
Default:
0,
Range:
0 or greater.
The type of lens flare to apply. Custom lens flare types can also be made, or existing types modified, by editing the flare in the flare designer.
Flare Details Parameters:
-
Rays Rotate:
Default:
0,
Range:
any.
Rotates the ray elements of the lens flare, if any, in counter-clockwise degrees.
-
Color:
Default rgb:
[1 1 1].
Scales the color of all flare elements.
-
Gamma:
Default:
1,
Range:
0 or greater.
Increasing gamma brightens the flare, and especially boosts the darker elements.
-
Saturation:
Default:
1,
Range:
any.
Scales the color saturation of the flare elements. Increase for more intense colors. Set to 0 for a monochrome lens flare.
-
Hue Shift:
Default:
0,
Range:
any.
Shifts the hue of the flare, in revolutions from red to green to blue to red.
-
Hotspot Color:
Default rgb:
[1 1 1].
Scales the color of the hotspot elements only.
-
Hotspot Brightness:
Default:
1,
Range:
0 or greater.
Scales the brightness of the hotspot elements only.
-
Rays Brightness:
Default:
1,
Range:
0 or greater.
Scales the brightness of the ray elements only.
-
Rays Num Scale:
Default:
1,
Range:
0 or greater.
Increases or decreases the number of rays.
-
Rays Length:
Default:
1,
Range:
0 or greater.
Adjusts the length of the rays without changing their thickness, or changing the size of the other flare elements.
-
Rays Thickness:
Default:
1,
Range:
0 or greater.
Adjusts the thickness of the individual rays within the flare.
-
Other Brightness:
Default:
1,
Range:
0 or greater.
Scales the brightness of all flare elements that are NOT at the hotspot location.
-
Other Width:
Default:
1,
Range:
0 or greater.
Scales the width of all flare elements that are NOT at the hotspot location.
-
Other Color:
Default rgb:
[1 1 1].
Scales the color of all flare elements that are NOT at the hotspot location.
-
Blur Flare:
Default:
0,
Range:
0 or greater.
If positive, the flare image is blurred by this amount before being combined with the background.
Other Parameters:
-
Scale Source:
Default:
1,
Range:
0 or greater.
Scales the brightness of the source clip before combining with the flare. If 0, the result will contain only the flare image over black.
-
Combine:
Popup menu, Default: Screen
.
Determines how the flare image is combined with the source image.
-
Screen:
performs a blend function which can help prevent
overly bright results.
- Add: causes the flare image to be added to the source.
- Add: causes the flare image to be added to the source.
-
Screen:

-
Tint Bg Whites:
Check-box, Default:
off.
If this is enabled, the chroma of the flare is added only after the result is clamped to the maximum brightness. This allows the color of the flare image to still be visible even over bright white backgrounds. For the majority of backgrounds there will be no observable difference.
-
Affect Alpha:
Default:
0,
Range:
0 or greater.
If this value is positive the output Alpha channel will include some opacity from the flare. The maximum of the red, green, and blue flare brightness is scaled by this value and combined with the Background Alpha at each pixel.
-
Performance:
Popup menu, Default: full flare
.
Determine whether to render all elements or only select elements. Certain elements are selected in the Flare Designer to be important for the look of the Flare. Rendering with priority only should give the look and feel of the true LensFlare for previewing purposes but render quicker than the full flare.
-
full flare:
Render all LensFlare elements.
- priority only: Only render a subset of the LensFlare elements for increased performance.
- priority only: Only render a subset of the LensFlare elements for increased performance.
-
full flare:
Render all LensFlare elements.
