Im in need of some serious help here. I cant sleep at night and and cant concentrate at work because i cant figure out this effect. I'vs tried Andrew Kramer's 3d tut but cant figure out how to do it for a person standingn the middle of the room.

check the 12 sec, 1:18 sec, 2:23, 2:31 marks.
Thanks guys.
 
I don't see what is the problem, this type of "effect" has been asked for many times before see:

Its very simple, roto out OR shoot actor against green screen, place background plane in 3d space (in AE) and then move your AE camera with some slight movements to give the impression of virtual move.

However you can not orbit the camera too far because the actor is only a 2d plane.

Follows these steps:

* Shoot actor against greenscreen OR Roto him out

* Shoot clean backplate

* make a new 3d compositon, place actor in one place, then

* place the clean bacground on another place, move it "back" in 3d space

* create a AE camera

* Create key frame moves for your AE camera

Thats its !

also if you want the guy to "freeze" then just use one frame of both plates.

Hope that helps.

Well the first one is easy but the other three seem like they were done with the camera (or expensive 3D software, but I don't think so) not with AE. You can have something sort of similar by doing this:

1. pick the frame you want to animate
2. select and crop your talent in photoshop from said frame
3. composite the cropped person over original footage.
4. when you freeze frame, animate the cutout's scale and position
5. adjust the position of the cutout and background scale/position as neccesary
6. if background is a solid or easily cloned, create more background for more play in the position of it vs. you talent

IMO I think they did a multi camera trick like bullet time in the matrix movies, but had the cameras lined up away from the action as opposed to circling it. It actually looks sweet.
 
If you look closely you can see parts of the talent's arm that were hidden from the beginning part of the move to the end. That means one of two things: he was a 3D model, or they used a camera trick like bullet time. But as long as you are happy with your results rock out!
 
This effect is probably done with a technique called Camera Mapping.
Essentially what you need to do, is take a still image, separate the elements you need some depth in into different layers. From here on you'll have to use a 3d package and you'll need to reconstruct the scene in 3d.

Here's a test I did a few weeks ago.

That was hot. I saw it on another thread. What software didi you use for that? AE and somthing else you mentioned?
 
Hi there,

Anhar Miah is right on this one, but it's actually very simple in this case.

the actor and background is seperated (in Photoshop, or AE with masks), the actor is moved forward in 3d space, camera pan is done, end of effect. With the actor moving forward becoming bigger it fills the hole in the background, so if you don't pan to much it won't show.

Otherwise just clone in the background.
