The Gradient Ramp effect creates a color gradient. You can create linear or radial ramps, and vary the position and colors of the ramp over time.
Use the Start Of Ramp and End Of Ramp properties to specify the start and end positions. Use the Ramp Scatter control to disperse the ramp
colors and eliminate banding.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
Ramps often don’t broadcast well; severe banding occurs because the broadcast chrominance signal doesn’t contain sufficient resolution to
reproduce the ramp smoothly. The Ramp Scatter control dithers the ramp colors, eliminating the banding apparent to the human eye.
Grid effect
Use the Grid effect to create a customizable grid. Render this grid in a solid color or as a mask in the alpha channel of the source layer. This effect
is good for generating design elements and mattes within which other effects can be applied.
John Dickinson provides a video tutorial on his Motionworks website that demonstrates the use of the Grid effect.
This effect works with 8-bpc color.
Use Grid with the Advanced Lightning effect to create lightning forks that follow a grid pattern.
The point of origin of the grid pattern. Moving this point offsets the pattern.
How the dimensions of the rectangles are determined:
The dimensions of each rectangle are the dimensions of the rectangle with opposite corners defined by the Anchor and
Corner points.
The height and width of a rectangle are equal to the Width value, meaning that the rectangles are squares.
The height of a rectangle is equal to the Height value. The width of a rectangle is equal to the Width value.
The thickness of the grid lines. A value of 0 causes the grid to disappear.
note: The anti-aliasing of the grid borders may cause the visible thickness to vary.
The softness of the grid.
Inverts the transparent and opaque areas of the grid.
The color of the grid.
The opacity of the grid.
The blending mode to use to composite the grid on top of the original layer. These blending modes work identically to the ones in
the Timeline panel, except for the default None mode, which renders the grid only.
Lens Flare effect
The Lens Flare effect simulates the refraction caused by shining a bright light into the camera lens. Specify a location for the center of the flare by
clicking anywhere inside the image thumbnail or by dragging its cross hair.
This effect works with 8-bpc color.
