RGB Split
Outputs the red, green, and blue color channels individually, depending on which button
you click. Each grayscale color channel can then be independently manipulated with
different node tree branches, before being reassembled using the RGB Merge node. This
node has three checkboxes:
• Red: Outputs the red channel.
• Green: Outputs the green channel.
• Blue: Outputs the blue channel.
Vignette
Creates a simple square or circle vignette. This vignette appears as a color-against-grayscale
preview if the Vignette node is viewed directly. When the results are viewed “downstream,”
by viewing a different node that’s processing its output, the true grayscale image is seen.
This node has the following parameters:
• Use Tracker: If you’ve analyzed one or more motion trackers in the current project, you
can choose which tracker to use to automatically animate the position of the vignette
from this pop-up menu. To disassociate a vignette from the tracker’s influence, choose
None.
• Shape Type: Lets you choose the type of vignette, either Circle or Square.
• Invert: Click this button to make the white area black, and the black area white.
• X Center: Adjusts the horizontal position of the shape.
• Y Center: Adjusts the vertical position of the shape.
• Size: Enlarges or shrinks the shape.
• Aspect: Adjusts the width-to-height ratio of the shape.
• Angle: Rotates the current shape.
• Softness: Blurs the edges of the shape.
