By digitizing someone, in this video, do you mean the blue-looking versions of the singers? To me, this just looks like an effect applied to the video, possibly Red Giant Trapcode Form, using the video as a depth map.
To me, digiting means actually creating a 3D person, then applying texture maps of the singer to the face and body of the 3D model. There's a way to do this using Daz Studio, which is free:

Joe's suggestion of using Form is good.
Check out the Form Face [link] tutorial, which mimics the 3D pin effect from the Radiohead "House of Cards" video.
