Although this is a really cool video, many of the facts are incorrect, including the A4's transistor count. A4 might have 32 million transistors, but certainly not 32 billion!
Got a tip for us?

What's the point of spending all that time on an animation if you run it so fast nobody has time to read anything? Is it really a video if I have to continually pause it?

I've changed my mind somewhat. It seems there is text they want you to read, and text that is more of a stylistic info-filler. The text they want you to read is on the screen long enough to read it. The rest is in a smaller font and zips by.
Still odd.

The A4 is not a CPU, it's a package-on-package stacked system on a chip. If you consider the A4 to also consist of the stacked SDRAM, then it includes at least 256 MB of SDRAM depending on the variant. That's 2 gigabits of SDRAM.
Each individual bit of SDRAM is built on top of a transistor, so an overall A4 system mush have at least 2 billion transistors just for the SDRAM portion of the SoC, before you start considering any other components of the device in the bottom layer of the stack such as graphics accelerator or ARM CPU.
It was created by UK firm Headspin Media:
"The 3D rotating objects were all created in Softimage XSI, which was then rendered and brought into After Effects, which is where we animated the rest of the video."
