Using composite slots
This article covers features that require activation via a module license.
A composite slot represents a composite of multiple input or library slots. It can be used to
- blend a foreground and a background plate
- configure a grid using multiple layout options
Adding and deleting a composite slot can be done via the ellipsis menu in the slot’s subtoolbar.

Configuring a composite slot can be done via the slot settings, which can be found in the slot panel on the bottom-right in the main screen.

Grading sources of composite#
A composite slot can be seen as a container for multiple source slots. To grade the individual parts of the composite, select the source slots and grade them.
If you want to avoid the current output changing its source when selecting an input slot instead of the composite slot, you can lock the output first.
