About paint strokes

Each time that you drag in an image with the Brush, Clone Stamp, or Eraser tool and create a paint stroke, After
Effects creates a separate paint item and duration bar in the Timeline panel. You can then use the Timeline panel to
change the stroke's position in time and to animate each paint stroke's shape, stroke options, and transform
properties.
Note: Eraser strokes made with the Last Stroke Only option can't be animated and permanently erase the targeted paint
stroke.
You can change a stroke's position in time by adjusting values in the Timeline panel's In, Out, and Duration columns,
in addition to dragging the stroke's duration bar. In addition, you can nudge a paint stroke's position, rotation, or
scale with the same keyboard commands that you use for nudging a layer.

Working with paint strokes in the Timeline panel

Once you have applied a paint stroke to a layer, you can modify the way the stroke interacts with the layer and the
composition by adjusting the blending mode, stroke properties, and transform properties in the Timeline panel.
Note: To move a paint stroke, change its Position property values.
