Glow is a bright haze surrounding an overlay. In general, light colors are used for glow effects, but you can emphasize bright text on complex backgrounds by using a very small black glow, with little or no feathering, and 100% intensity.
1.Select the 2D Glow row in the keyframe controller. When the 2D Glow row is selected, glow controls are displayed in the Track Motion dialog.
Select the 2D Glow check box to apply the glow so you can see the results of your shadow in the Video Preview window, or clear the check box to bypass the glow.
