How to make a fake 3d effect (The Matrix 3d rotation style) from 2 video sources?
This is possible, though it wouldn't look real at all.. If you use Adobe After Effects you can just put both sources in one composition. Then you would turn on the 3D-mode on each of the layers. There is a button on each layer. If you click it there should be a small picture of a cube where you clicked.

Then you press P on each of the layers to bring up the position sliders. Then you animate the first layer until it "matches" the position of the second camera. (The axis that goes from the top of the image and downwards.) Do this for both the layers and just blend them together. I don't remember if you have to insert a camera into the scene too. So you basically move the layers to simulate movement. Oh, and add motion blur too with the motion blur button next to the 3d-button. Remember to switch on the master blur button too. This will make the camera movement (or in this instance the movement of the layer itself) look more natural. Remember to zoom in a bit into the comp to compensate for the 3D.

Please post your video so we can see how it looks! :)
