The person who did this animation, I think is also the author of the software.

In the documentation he recommends a Quad Core system.

I ran the program on my Single Core PC and it took about 2 minutes to render a small image, and I did a zoom and that took another 4 minutes to render.

I have no idea how he manged to create a keyframe path and do all that camera work and make it look so good, must be a lot of pre-determined calculations and planning.
