# Creating Customized Wipes with Masks

Use masks on the incoming clip to create a customized transition that wipes into the outgoing clip.

Before you create a mask, set how the points of the mask are drawn.

To set the drawing options:

1. From the Wipe Editor, click Setup.
2. Specify the setup options.

   Enable: | To:
   --- | ---
   Auto Tangents | Create tangents for every new point you set.
   Show Border | View the border defined in the Offset field of the Shape menu. The colour pot next to the Show Border button defines the colour of the border.
   Invert | Reverse your wipe. For instance, if you originally create an expanding box wipe, enabling Invert creates a shrinking box.
   Spline Keyframing | Allow animation of points on the mask.

3. To change the colour of the mask's wireframe, colour points, or offset border, click a colour pot and pick a new colour.

An Axis node contains all the rotation, scaling, and position data for the mask. You can change all this information in the Mask menu. The Axis controls are identical to those in the Action Axis menu.

You can animate the following mask properties:

- The characteristics of the camera in the scene
- The position, rotation, scaling, and shearing
- The mask shape
- The offset, border offset, border alpha, colour, and opacity

To display the Animation menu, click the Animation button.
