Andrea:

1- thanks for the boxblur plugin. If you cover your dog's ears, could
you try asking GG to create a small blur region so you have a
censorship rectangle to apply to the video? :-)
GG only giggled when I mentioned this so the dog is fine and he will look into it to see if it can be done.

2- I keep having problems with the Z-axis slider in the
chamber/projector. Is it possible it's just me? It only works by
entering the number in the textbox or the arrows next to it. If you
touch it, the slider jumps to a random number (magnification) and no
longer moves from there. The slider does not work and the arrows next
to it do not work.
Thanks for the video - after watching it I think I can duplicate the issue.  It might have something to do with the zoombar settings on the bottom of the timeline.  I will have to show and ask gg when he becomes available again.
