Nodes
The Node view uses a visual set of connections (nodes) to show how each element in the scene is connected and brought to the final image. It allows you to add extra elements and effects, and to move beyond the possibilities offered by the Timeline and Xsheet views. Each node corresponds to a layer in the Timeline view. Very few nodes are only visible in the Node view.
The basic rules of the Node view are quite simple. Once you understand them, a lot can be accomplished.
Each node used to build a node system is available in the Node Library view as well as through the Insert menu in the Node view. In addition, each time you create a layer from the Timeline or Xsheet views, the corresponding node is created in the Node view.
