# Transforming the Mask

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.

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

To transform a mask:

1. Access the Garbage Mask menu.

   The Axis controls appear.

   NoteThe Axis controls are similar to the Axis menu in Action.
2. Use the Transformation fields to modify the position, shape, and size of the mask.
