This 50 second CGI animation short demonstrates just how flexible 3D animation can be over traditional film footage methods. This is a linear animation there are no editing cuts. The post production elements in the animation, the HUD and copy are added in After Effects.
Concepts such as this would probably be difficult and certainly very costly to produce on film. 3D animation in contrast provides the freedom to realise your ideas. The Client is often surprised when this is all within their budget to achieve this.
