# Accessing the Keyer

You load three clips into the Keyer to create a composite: a front clip, a back clip, and a key-in clip. The key-in clip, which is usually the same as the front clip, is used to create the matte for the front clip.

You can also access the Keyer in Action and as a node in Batch and the Modular Keyer. See Keyer Node and Accessing the Colour Corrector and the Keyer from Action.

To access the Keyer module:

1. In the EditDesk menu, select and enable Effects from the Menu Priority box.
2. Click Keyer.
3. Select the front, back, and key-in clips. Make sure the front, back, and matte clips are the same resolution. If not, resize them. See Accessing Resize and Resize Settings.
   TipUse the S option on the Keyer button on the EditDesk to automatically load the same clips used in the previous session. Click the S option, and then select the destination.
4. Select the destination.

   The Keyer appears.
