How do I reference specific nodes in a callback?
I’ve gotten as far as selecting specific nodes but I’m a little confused at how 
I’m actually
referencing actual knobs in these nodes.  I feel like it should be with a 
"nuke.thisNode()” type approach but I can’t seem to get it working.

Is this the right idea?

def CallbackTest():
        allNodes = nuke.allNodes(recurseGroups=True)
        for n in allNodes:
                if "Read" in n.name():
                        path = “./User/movies/videofile.mov"
                        nuke.thisNode().knob(‘file').setValue(path)




Thanks!

Michael
