Select, lock, and disable control points

There are many ways to select and deselect control points that you want to modify. You can also lock control points to prevent changes, or disable them to temporarily remove them from a mask shape.

Select control points

In the Viewer, do one of the following:

  • Click any control point.

  • Shift-click unselected control points to add them to the selection.

  • Shift-drag a selection rectangle around unselected control points in a closed mask to add them to the selection.

  • Drag a selection rectangle over multiple control points in a closed mask.

Deselect control points

Do one of the following:

  • Shift-click selected points.

  • Shift-drag a selection rectangle over selected points.

Select or deselect every control point on a mask

  • To select all of a mask’s control points: Choose Edit > Select All (or press Command-A).

  • To deselect all of a mask’s control points: Choose Edit > Deselect All (or press Shift-Command-A).

    You can also click anywhere outside the selected mask in the Viewer.

Display the control point number

By default, mask control points are numerically labeled in the order in which they were created in the Viewer.

  • Position the pointer over any control point in a closed mask.

    The numeric name of the control point appears—“Control Point 1,” for example.

Note: Draw Mask control points are also listed by number in the Draw Mask section of the Video inspector.

Lock control points

You can lock control points in a mask to fix them in place and prevent accidental changes.

  • Control-click a control point, then choose Lock Point from the shortcut menu.

    To unlock a locked control point, Control-click it, then choose Unlock Point from the shortcut menu.

Disable control points

Disabling a control point in a Draw Mask is similar to disabling a clip in the Timeline: the control point is temporarily removed from the mask but retains its position and its number in the sequence of control points. You can just as easily reenable control points.

  • Control-click a control point, then choose Disable Point from the shortcut menu.

    To enable a disabled control point, Control-click it, then choose Enable Point from the shortcut menu.
