As much as callbacks are cool and powerful, I have seen them over used
quite a bit which brings Nuke to a crawl and can cause all sorts of
errors that are hard to debug. So I always try to go with the least
"invasive" one and doing lots of context/error checking first to leave
the custom function as soon as possible if it's not meant to be fired
under certain circumstances.

Hi Frank and Jesse,
I gave it a try with the knobChanged Callbacks and I like the instant
feedback.
Sofar it is much better than having the python function in the file
knob (I think I ll never do that again)
But I guess you are right for a the most minimalistic beforeRender is
the best choice
thanks
Johannes

why not use the beforeRender callback to only process things when
they will be needed?
I agree with Frank on this one. When I suggested the onKnobChange
callback, I was assuming you were doing some simple validation, but I
see now that you are interested in auto-filling the output path,
which should only be important before render.
