I am 100% sure this demo reel was rendered with Vue, what do you assu,e it was rendered with? Making animatings in vue takes a bit practice to get everything flicker-free.

 

Theres some nice videos rendered by users at cornucopia, some would require more anti-aliasing to compete with the e-on video, but keep in mind that most users there do not have large render farms to render in such a quality. I guess for using all scenes in the demo video in this quality your computer could be rendering several weeks.

I have no doubt that they made the video with vue 6, but also have no doubt that you need a lot of experience to make and cutting in this quality.
