So from what you guys have said, if you're on 6.2, this is the expression to
use, Julian:
parent.input0.format
But Ron says that setting the format knob through the interface isn't
working, so I would try through python:
g = nuke.toNode('mygroup')
g.begin()
c = nuke.toNode('myCheckerboard')
c.setExpression('parent.input0.format')
g.end()
Replace mygroup and mycheckerboard with the actual names and that should
work
