Open the custom layout editor for a channel

1. Login to the Admin panel as admin, see Connect to the Admin panel.
2. From the Channel(s) menu, select the channel and click Layout(s). The custom layout editor opens.
3. From the Layouts list, select the layout you want to edit. The layout editor updates to display the selected layout and the row for the selected layout is highlighted in green.

If this is a new layout, an unformatted layout, or there is no video source connected, then the layout area is empty and a black background matte appears.
