Answers

1.Rotoscoping is a frame-by-frame shape-drawing technique used to create animated shapes over time.
2.The Toggle Fill/No Fill mode button toggles the rendering of shapes on and off.
3.The four knot modes are Group, Main, Edge, and Any, and they are used to control softness of a shape on a knot-by-knot basis.
4.Motion blur is used to reduce strobing and to smooth out moving objects.
5.You should create as few keyframes as possible to animate the shape, but enough so that the shape follows the object properly.
