Stretching Pixels in Z
So an image has been camera projected onto a cube in Nuke. The cube is scaled on the Z axis creating the pixels to stretch past camera. I have gotten something close using reverse camera optics in After effects, but it blurs the image to much. I don’t want to use any blurs. I want the center pixels to stretch past camera. It would feel like a zoom.
Any thoughts?Thanks

You should be able to do basically the same thing in AE by using a camera projection technique detailed in Mark Christiansen’s fantastic book:
AE CS3: Professional Studio Techniques

Just make sure you create your cube from white solids, accept shadows, don’t accept lights and build it in a pre-comp. Then drop that pre-comp in your projection comp, turn on collapse transformations and scale it on the Z-axis to extend the projection.
You’ll want to increase the Shadow Map Resolution (in Composition Settings > Advanced) to something high so the shadows don’t blur (also don’t use shadow diffusion).
