7. Adjust the onscreen controls to specify which part of the video image is affected by the
color correction.
• Position the shape: Drag the center.
• Adjust the shape’s width or height: Drag any of the four handles at the 90-degree
points (top, bottom, left, or right) of the inner circle. You can hold down the Shift key
while dragging to force all sides to scale proportionally.
• Control the roundness of the shape: Drag the handle to the left of the inner circle’s
top handle.
• Rotate the shape: Drag the rotation handle (extending from the center).
• Control the softness of the shape’s edge: Drag the outer circle. Setting the outer
circle close to the inner circle creates a hard edge and an abrupt transition to the
corrections you apply, and dragging the outer circle away from the inner circle
creates a softer edge and a more gradual transition.
