Controls in the Motion Tab
The following section describes the attributes and related parameters in the Motion tab
of 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: 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
Change a clip’s Crop parameters to crop a clip and feather or soften the edges so that
they blend into the background when compositing.
 Left, Right, Top, Bottom: 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: Applies a soft border with its outer edge at the crop line. The higher
you set the Edge Feather parameter value, the farther into your clip the feathering
effect goes.
Keyboard Modifiers for Controls in the Motion Tab

Command key.
When using an Angle control (a dial):
 To constrain the dial to 45-degree increments, hold down the Shift key.
 To slow down a dial’s movement and select a more precise value, hold down the
Command key.
 To reset the parameter value to 0, drag out of the dial.
