# Creating Customized Wipes with Garbage Masks

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

## Setting the Mask Drawing Options

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 colour.
