• Use the arrow keys to pan the center point by 1 pixel. Press Shift as you press an arrow key to adjust the point by
10 pixels. Press Ctrl (Windows) or Command (Mac OS) as you press an arrow key to adjust the center point of the
opposite set.
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.
Anchor The point of origin of the grid pattern. Moving this point offsets the pattern.
Size From How the dimensions of the rectangles are determined:
• Corner Point The dimensions of each rectangle are the dimensions of the rectangle with opposite corners defined
by the Anchor and Corner points.
• Width Slider The height and width of a rectangle are equal to the Width value, meaning that the rectangles are
squares.
• Width & Height Sliders The height of a rectangle is equal to the Height value. The width of a rectangle is equal to
the Width value.
Border 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.
Feather The softness of the grid.
Invert Grid Inverts the transparent and opaque areas of the grid.
Color The color of the grid.
Opacity The opacity of the grid.
Blending Mode 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.
