The region is drawn by adding nodes along your region. These act as edges for your rotoscope, and there is a line between each node. The line between each node can be made into a Bézier_curve using "handles".
Add nodes to the node by left clicking the mouse.
Close the region by right clicking the mouse on one of the noedes
Change the position of the region by moving a node.
Make a line curved by dragging the control "handles". These are the two dots on the ends of the straight lines that appear on the curve (see screen shot above).

To define if it is the inside or the outside of the curve that is transparent toggle the invert checkbox.
