# Setting Up Viewports for Keying

After you have set up your processing pipeline and your media, you want to set up the viewports for keying.

When keying, you want to set the viewport to 2-up view, to display the schematic and the result views simultaneously, enabling you to view the result as you work.

To set up the viewports for keying:

1. From the Layout box, select 2-up.

   The view area is split in two. The schematic view is displayed on the left, by default.

2. Click in the right-side viewer to select it.

   A white frame appears around the viewer to show that it is selected.

3. From the View box, select Result.

   The result of your key, in its current state, is displayed in the right-side viewer.
