Adobe Live - Graphic Design - Animated Movie

The promo video at the end could be mostly cut in Premiere Pro.

A few of the transitions would have to be done in a Motion Graphics app like After Effects, but these kinds of transitions,

can easily be done with prepared artwork. The portraits prepared with Photoshop, and the background art photographed, added to a Premiere Pro sequence with a title overlay. You could also do them in AE but they could have been easily done entirely in Premiere Pro.

This shot, where the Eyes blink, would be easiest to do in After Effects.

Animated graphics like this one at the end would also be easiest to create in AE:

Some of the shots were just speeded up screen captures. My point is that all of that promo video could have been created in After Effects, trying to cut it together all in a single AE comp would be an insane way to approach the project. Trying to cut and time the hundreds of layers in a single AE comp would have created a comp that was nearly impossible to creatively edit and adjust.

When approaching a project like that promotional video the best approach is to write out a script and make at least a simple storyboard, then figure out the easiest way to create each shot in the project. AE is best suited to creating shots, an editing app like PPro is best suited to editing a sequence. My guess is that the promo video was created with a combination of tools. The editor may not have been the same person as the graphics designer, who may not have been the same person that gathered the images and did the Photoshop work.
