Rectangle Mask tool can be set to Rectangle, Circle, Freehand, Bezier, or B-Spline mode.

Slider Controls
Sliders are used for parameters that span a range of numeric values. Sliders are by far the
most common control type in Motion.
Basic Sliders
Sliders are used to set values in a fixed range. For example, opacity must fall between 0%
and 100%. Drag the slider to set a value anywhere within that range.
Although sliders are fixed-range controls, some parameters can be set to values outside
of that limited range. For those parameters, a second type of slider control is available: a
value slider, which is described in the next section. For example, the Amount slider in the
Gaussian Blur filter has a default range of 0 to 64, but can be set as high as 600 using the
accompanying value slider.
To change the value of a basic slider
µ
Drag the slider to the left to decrease values and to the right to increase values.
µ
Option-click to the left or right of the slider to decrease or increase by a value of 1.
