Movie Clip Node
This node is a special node that uses some of the values taken from footage cameras and trackings and link them to the output. It is possible to load image sequences, but only Image and Alpha values will be available, because the other outputs will not have any values associated with them. When a tracked clip is chosen, Blender will fulfill the outputs using internal values taken from the tracking. So the controls for start and end frames will be defined in the Movie Clip editor.
Inputs
This node has no input sockets.
