    This effect animates strokes on a layer. For example, you can simulate the writing of cursive text or create snakelike movement for a stroke. Use this effect to animate the brush size, color, hardness, and opacity of a stroke. After Effects Production Bundle also includes the Vector Paint effect, which you can also use to animate strokes. For more information on Vector Paint, see About Vector Paint (PB only).

    Animated strokes on a layer, with the stroke changing various properties over time

    At each keyframe, you can apply a new property value to the current segment of the stroke, or you can apply the value to the entire stroke. For example, you can make a stroke become gradually thicker as it is drawn by increasing the stroke's brush size at each keyframe. You control whether a property is applied to stroke segments or to the entire stroke using the Paint Time and Brush Time menus.

    In addition, you can apply a stroke to the original layer or to a transparent layer. Applying a stroke on a transparent layer is useful when you want to use the brush stroke as a track matte or when you want to combine it with other layers using blending modes. With this effect, you can use an open path to create the stroke.
