Creating Customized Wipes with Garbage Masks

Use masks on the incoming clip to create a customized transition that wipes into the outgoing clip. Depending on the type of wipe you are creating, perform some or all of the following procedures:

Set the mask drawing options. See Setting the Mask Drawing Options.
Draw the mask. See Creating a Mask.
Adjust the mask's shape. See Altering a Mask's Shape.
Set the mask effect. See Controlling a Mask's Effect.
Adjust the position, rotation, and scaling of the mask. See Changing a Mask's Position, Rotation, and Scaling.
Animate the mask parameters. See Animating Masks.
For more information about working with garbage masks, see Garbage Masks.

Setting the Mask Drawing Options

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

To set the drawing options:

From the Wipe Editor, click Setup.

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.

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