Chaining merge nodes together

Merge nodes only process two images at a time, foreground and background. To add

additional images, often called elements or plates, to a composite, you must chain merge

nodes together using the output of one merge as the foreground or background of another

merge. That’s how you’ll add a scratched glass element that we’ll again get from the

mediapool.

1 In the upper-left corner of the interface, click the media pool button.

2 From the master bin, drag the glass clip to an empty area of the node editor.

3 Press 1 to see the image in viewer 1, then press F2 to rename this node, GLASS.

This is the image we will composite over the top of the ACTRESS and the HUD.

4 In the node editor, select the merge 1 node.

Instead of dragging from the toolbar, selecting a node allows you to click a tool in the

toolbar and connect it into the selected node.

5 In the toolbar, click the merge tool.

The output of merge 1 is now connected to the yellow background input of merge 2.

You can use the unconnected green foreground input on the merge 2 node to connect

the scratched glass image.

6 Drag the output of the GLASS node to the green foreground input of the merge 2 node.

With the glass node connected, you can use the merge node to blend the images to

create more realism.
