Render Layers Node
This node is the starting place for getting a picture of your scene into the compositing node tree.
Select the scene within your blend-file. The scene information taken is the raw footage (pre-compositing and pre-sequencing).
To use composited footage from another scene, it has to be rendered into a multi-layer frameset (e.g.
OpenEXR) as an intermediate file store and then imported with Image input node again.

A list of available Render Layers. The render button is a shorthand to re-render the active scene.

Depending on the Render passes that are enabled, other sockets are available. See render passes.
