Controls in the Motion Tab
The following section describes the attributes and related parameters in the Motion tab
in the Viewer.
Basic Motion Parameters
The Basic Motion parameters allow you to add motion to a clip—changing the scale,
rotating a clip, moving the center point, and setting an anchor point.
 Scale slider: Changes the overall size of a clip without changing its proportions.
 Rotation: Rotates a clip around its center axis without changing its shape. Clips can
be rotated plus or minus 24 rotations.
 Center: Specifies the center point of the clip, allowing you to move a clip somewhere
else in the frame. The center parameter actually refers to the location of the clip’s
anchor point in the Canvas.
 Anchor Point: Specifies the point that is used to center a clip’s position and rotation.
A clip’s anchor point does not have to be at its center.
Crop Parameters
 Left, Right, Top, and Bottom sliders: Crops the clip from the specified side. You can
crop the top, left, right, and bottom of a clip independently. Values in the number
fields represent pixels.
 Edge Feather slider: Applies a soft border with its outer edge at the crop line. The higher
you set the Edge Feather slider, the further into your clip the feathering effect goes.
