Lights the input clip using one or two spotlights.
For each enabled light, the intersection of a 3D light cone with the
image plane is calculated using the given light source position, aim
location, and beam angle. Ambient light can also be applied to
affect the entire source image evenly. A wide variety of lighting
shapes can be created by adjusting the parameters provided.
In the Sapphire Lighting effects submenu.
Background: The current layer. The clip to combine the light with.
- Light1 Enable: Check-box, Default: on.
Turns on or off this spotlight.
- Light1 Bright: Default: 0.8, Range: any.
Scales the brightness of this spotlight. This
value can be made negative for a 'dark' spotlight effect.
- Light1 Color: Default rgb: [1 1 1].
Determines the color of this spotlight.
- Light1: X & Y, Default: [180 360], Range: any.
The position of this light source relative to the image plane.
- Light1 Z: Default: 180, Range: 10 or greater.
The distance of this light source from the image plane.
Decreasing this brings the light source closer to the surface and
causes the direction of the beam to be more parallel to the surface,
which can stretch the spot into an ellipse or hyperbola shape.
- Aim1: X & Y, Default: [300 243], Range: any.
This spotlight is directed at this location on the image
plane. If this is directly under the Light Source a circular spot
will result. When moved away from the Light Source it can also cause
the spot to change to an ellipse or hyperbola shape.
- Spread Angle1: Default: 45, Range: 0 to 360.
The spread angle of this spotlight beam in degrees.
Larger values open up the beam for a larger spot.
- Softness1: Default: 0.3, Range: 0.01 to 1.
Determines the amount of penumbra or the softness of the
spotlight edges, relative to the Spread Angle. Lower values make
crisp edged shapes, higher values make softer shapes.
- Falloff Power1: Default: 0, Range: 0 or greater.
Determines how much the spotlight brightness fades
with distance. A value of 0 causes no fading, 1 fades the light as
distance increases, and 2 fades it faster with distance. A value of 2
is correct for a physically realistic point light.
- Light2 Enable: Check-box, Default: off.
Turns on or off the second spotlight.
The remainder of the Light2 parameters are the same as those
described above for Light1, but control the second spotlight instead.
- Ambient Bright: Default: 0.2, Range: any.
The amount of ambient light included in the entire
frame. This allows parts of the Background outside of the spotlights to
still be visible if desired.
- Ambient Color: Default rgb: [1 1 1].
Determines the color of the ambient light.
- All Lights Bright: Default: 1, Range: any.
Scales the brightness of all the spotlights together.
- All Lights Color: Default rgb: [1 1 1].
Scales the color of all the spotlights together.
- All Aims Shift: X & Y, Default: [0 0], Range: any.
Adds this amount to all lights Aim parameters. This can
be used to easily make all lights aim at the same location.
- All Shift: X & Y, Default: [0 0], Range: any.
Shifts the entire spotlight pattern without changing
their shapes by adding this amount to all light and aim positions.
Popup menu, Default: Mult.
Determines how the light is combined with the Background.
- Lights Only: gives only the light image with no Background.
- Mult: the light is multiplied by the Background. This is
the effect that a real light would typically have.
- Add: the light is added to the Background.
- Screen: the light is blended with the Background using a
- Overlay: the light is combined with the Background using an
