An interesting technique is to cause a piece of footage to appear to be projected onto other items, as if it was coming from a video or film projector. This can be done with the 3D capabilities of After Effects, but it requires knowledge of a little-known parameter: Light Transmission. In this tutorial on Artbeats.com, we show how to set up a 3D environment that takes advantage of Light Transmission to create this look, plus share some tips on how to improve the final image, including sharpening (or blurring) the projection, and using “negative light” to crop unwanted light from spilling around the edges of the image.
