Parallax Effect

Can this be done in Motion:

Yes.

You can do all these things in Motion - the online help will guide you on how to translate each task into the way Motion does things.

'Pre-comping' in After Effects is 'Grouping' in Motion. In the example he gives he created a layer out of each body part and then combined them into a group. You'll need to set the anchor point of each body part so that it is the pivot around which it rotates.

All the other terms you'll find by searching Motion Help.

By the way, if this was easy and straightforward to do, it would be so common as to be not worth doing, so you'll have to invest some time to work it out. I suggest that you don't do the precomp and moving parts of one of your layers until you've worked out the rest of the technique with each layer remaining the same even as you animate the camera and animate the position and angle of each layer.

Very cool.

I definitely want to give this a try.
