I'm not entirely sure about that...
If you are on Facebook, try joining the Mandelbulb Maniacs group on Facebook and post the question there, as there are a number of very good and very experienced animators there...
If you are not on Facebook, try asking CPMacDonald (
cpmacdonald.deviantart.com/) as he might know the answer or know somebody who does...
Sorry I could not be more help
