Combining an OFX key with a window using a Key Mixer to add a Garbage matte
Compositing Entirely Within an OFX Plug-In
Certain OFX plug-ins that are capable of combining two image streams to create a composite
can be used as of DaVinci Resolve version 11.1 by exposing a “second layer input” on the node
to which that plug-in has been applied. This makes it possible to composite the image you’re
grading with the RGB output from an EXT MATTE node.

in applied to it
To create a composite using an OFX plug-in:
1 Open the OpenFX Panel, use the Library to find the OFX compositing plug-in that you
want to use, and drag it onto the appropriate node to apply it. The above example
shows the Boris Effects plug-in “BCC Composite,” which mathematically combines two
image streams using one of a long list of blending modes.
2 Right-click the node with the OpenFX plug-in applied to it, and choose Second Layer
Input from the contextual menu. A second RGB input should appear on the left of the
node, underneath the first.
