You can apply transformations such as translation, rotation, scaling, shearing, and centre changes to a garbage mask. The transformation data for the mask is stored in its Axis node. You apply transformations to the mask using the Axis controls.

All transformation parameters in the Axis menu can be animated. You can use a motion path to animate the position of a mask. See Creating a Motion Path.

You can also apply motion blur to a garbage mask. See Applying Motion Blur to Garbage Masks.
