How does that work?

Hello,

I found a Video on a Website where a Team of 3D Artist created a Video Footage and replaced the Items in the Footage with 3D Object (Houses, Trees etc.) Im wondering how they replaced that how that exactly works it would be pretty cool if somebody can explain me how this works

Google camera matching. Short summary - analyze footage to figure out position/movement of camera, then create digital stuff to be composited into the footage, apply same settings for digital camera as the real one including the movement, then composite the render over the footage and do all the corrections.
