You could test the format to see if it is part of the root. If not, add
it before setting it
#Create a checkerboard and select the node you want to extract the
format from...
def set_format():
c = nuke.toNode("CheckerBoard1")
if nuke.selectedNode().format().name() == None:
f = nuke.selectedNode().format()
format = "%s %s %s %s"%
(f.width(),f.height(),f.pixelAspect(),"Hello")
nuke.addFormat(format)
c['format'].setValue("Hello")
else:
format =nuke.selectedNode().format()
c['format'].setValue(format.name())
set_format()

Salut Hugo,
Thanks for the tip. Yes, this works for me too. However this will
fail if the current format of 'blur' is not named (for example by
inheriting a format created by a Read node loading some random
image).
