Use the Glow node to create a glow effect on a clip. Customize the glow by selecting the RGB blur type and blending mode. The Glow Node accepts a front clip and matte clip as input. You can refine your glow further using colour correction, matte restriction, and RGB channel offsets.
Glow and Front Parameters Displays the controls to customize the glow’s blur effect. In the RGB Blur Type box, select Gaussian, Box, or Directional to apply a blur and enter blur parameters for the front clip. See RGB Blur Node.
Matte controls Generate and control the matte’s behaviour. Enable the Auto Matte button to generate matte values from the front clip. Set the value in the Expand field to enlarge the white area of the matte. Enable Lock Expand to make this value directly proportional to the Width value of the blur.
Blending controls Provides the logical operations that can be used to blend the front and the result. Use the Transparency field to set the percentage of blending when the result is composited on the front clip. See Using Logical Operations.
Colour Correction controls Displays colour correction tools to modify glow colour values. See Colour Correcting from the Main Menu.
RGB Channel controls Displays weighted value and offset of each blurred color channel.
