Hi
I have achieve this effect, importing the frame to photoshop and separating each thing into different layers.Then you re-build the layers (the background have to be completed by Photoshop work)
Then, make a 3D comp. where you can move your camera and you will fell the “matrix fx”.
The best way is to setup a still camera in the same position as your video one (take a still in the moment you want the FX to ocurr), so when you build your layers you have enough resolution to “travel” with your AE camera.
Lots of work, but the result is unbeliavable.
hope it helps
