Input NodesΒΆ
Input nodes produce information from some source. For instance, an input could be:
- Taken directly from the active camera in a selected scene,
 - from a 
JPG,PNG, etc. file as a static picture, - a movie clip (such as an image sequence or video), or
 - just a color or value.
 
These nodes generate the information that feeds other nodes. As such, they have no input-connectors; only outputs.
