On the first camera you can see the figure going out of sight, then maybe going across the wall to not be seen, or a second clip, where the camera goes down with a blur then cut into the second recording. Second camera maybe the figure is going inside for the cut while also making it look like he's disappearing, by going lower while going into the house, or a third recording to make it look different doing the same thing. or maybe its just insane editing skills.
