• All Premultiplied Samples the average of all RGB color values, premultiplied with the alpha channel.
• Including Alpha Samples the average of all RGB color and alpha channel values. The result is that the sampled
color also contains the average transparency of the sampled pixels.
Maintain Original Alpha When selected, the effect maintains the original clip’s alpha channel. If you choose
Including Alpha from the Average Pixel Color menu, the original alpha is stenciled over the sampled color.
Blend With Original The effect’s transparency. The result of the effect is blended with the original image, with the
effect result composited on top. The higher you set this value, the less the effect affects the clip. For example, if you
set this value to 100%, the effect has no visible result on the clip; if you set this value to 0%, the original image doesn’t
show through.
Grid effect
Use the Grid effect to create a customizable grid. Render this grid in a color matte or as a mask in the alpha channel
of the source clip. This effect is good for generating design elements and mattes within which other effects can be
applied.
Original image (left) and with variations of effect applied (center and right)
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 Each rectangle’s dimensions are those of the rectangle with opposite corners defined by the Anchor
and Corner points.
• Width Slider A rectangle’s height and width are equal to the Width value, meaning the rectangles are squares.
• Width & Height Sliders A rectangle’s height is equal to the Height value. A rectangle’s width 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 clip. The default None mode
renders the grid only.
Lens Flare effect
The Lens Flare effect simulates the refraction caused by shining a bright light into the camera lens.
Flare Center Specifies a location for the center of the flare.
