Hi from 7 degrees C cold & dark York UK :-(

Within the tools rolled out within Abode creative suite i need to animate the blades opening and closing within a camera lense. Below are some links to illustrate what I mean by the aperture blades opening and closing:

Now I believe from a rookies perspective to do this i would have draw in illustrator the blades then scale up in After effects and work through the animation via after effects.

What would be very helpful would be how somebody else would approach this using the abode CC suite only (I dont have anything else ). The motion of the blades and how i could replicate this does make me feel I could have a marathon of learning tutorials to overcome but some pointers would be much appreciated.

And finally here is an example of the aperture blades moving at 23 seconds, an effect I need to build as an animation:







Any insights welcome :-)

Consider yourself lucky. It's minus 9 celsius where I am. At least you're above freezing.

There's an OLD tutorial here on the COW by Rick Gerard that does this using AE & Illustrator for the iruis blades. Haven't found it yet.

I think this is the tutorial Dave is referring to:

or this one:
