4. In the Draw Mask section of the Video inspector, click the Transforms disclosure
triangle to open the Transforms controls.
5. Adjust the Position, Rotation, and Scale parameters to precisely define the shape, size,
and position of your mask.
Move a mask edge
You can change a mask shape by dragging its edges.
1. In the Final Cut Pro viewer, click any edge of a mask.
The control points on either end of the line are selected.
2. Drag the line segment.
The distance between the two points remains constant as you drag. Press Shift to
constrain the movement horizontally, vertically, or diagonally.
Edit Bezier control points in Final Cut Pro
You can adjust Bezier control points to draw any mask shape you may need. Each point in a
Bezier shape can be converted between a linear (corner) point and a smooth (Bezier) point
at any time. For more information about smooth and linear points, see Intro to complex
masks in Final Cut Pro.
Convert control points between corners and curves
On a mask in the Final Cut Pro viewer, do any of the following:
• Command-click a smooth (Bezier) point to turn it into a linear (corner) point.
• Command-drag a linear (corner) point to turn it into a smooth (Bezier) point, creating
adjustable tangent handles.
• Control-click selected points and choose either Linear, Smooth, or Very Smooth (for
B-Splines) to change the control point type.
Adjust a Bezier curve using a control point’s tangent handles
Bezier control points on a mask in the viewer have two tangent handles that you use to
adjust the curvature of the shape on either side of the control point. These handles can be
adjusted in various ways to create symmetrical and asymmetrical curves. By default, these
tangent handles are locked to one another at an angle of 180 degrees, but you can override
this restriction to adjust each tangent handle independently.
