Multiple outputs on nodes means a single node can connect to many different nodes in your
composition, so you don't have to duplicate clips as you would in layer based software.
Arrows on the line between connected nodes are a great visual indicator to show you which
direction the image data is flowing.
Adding Nodes to the Node Editor
Adding effects is as simple as placing nodes on the line between the 'mediain' and
'mediaout' nodes.
There are a few ways you can do this. You can hold down the shift button and drop a node
between two nodes, or click on the node you want to attach an effect to and select the
tool you want to add. The new node will automatically connect to the tool selected. You can
also add a node anywhere on the node window and manually connect nodes by dragging the
output of one to the input on another.
The most commonly used tool is the 2D or 3D merge node. This node is like
a central hub that combines tools on the node editor into a single output.
The merge node has controls for how the inputs are managed, including settings for size,
position, and blend. These settings are all accessible in the inspector panel when the merge
node is selected.
The toolbar above the node panel contains the most commonly used tools as icons that you
can either click on to add the node, or drag the tool to the node panel. If you want to see all the
complete tools available, click on the 'effects library' in the top left corner and expand the 'tools'
option. Here you'll find all the tools sorted by category, as well as a set of pre-built 'templates'
you can use, for example lens flares, shaders and backgrounds.
TIP
Once you're familiar with the tool names, you can hold down 'shift' and press
'spacebar' on your keyboard and a 'select tools' menu will appear. As you type the tool
name, the menu will suggest the relevant tool. This is a very fast way to select the tool
you want.
