For sure you will find better answer than mine, but here is what I know.

- In my point of view. will be easier for me to have the real footage shot first and than you create the animation.
- Which program they use I don't know but I have Premiere that can do it too.
- All real shots should use Chromakey color in the background if you want to add the reel shots over the animation. Or the Animation with Chromakey color in the background if you want to add the animation over the real shots.
- Use Premiere to apply the Chromakey over the color you choose and have it on the top layer.
