The node bins contain all the nodes needed to build a process tree. The nodes are divided into the following three groups, classified by tabs:

• An I/O bin, which contains the Desk node, the Library node, and the MUX node. Use the Desk node to load clips directly from the Desktop and the Library node to load clips from local or remote libraries. The MUX node allows you to have multiple outputs from one input. You cannot customize this bin.
• A Modular Keyer bin, which contains all Modular Keyer nodes classified into the All Nodes tab. The other tabs in the Modular Keyer bin allow you to create and customize bins. See Customizing the Modular Keyer Bin.

  The nodes in the All Nodes bin are listed in alphabetical order from top to bottom of each row. The All Nodes bin does not contain the nodes found in the I/O bin. You cannot customize the All Nodes bin.

• A User/Project bin, which contains custom nodes classified by a User tab and a Project tab. Use this bin to save custom setups per user or project. See Creating Custom Nodes.
