Re: Wrap a video clip around an object in AE by Joseph W. Bourke on Jan 22, 2014 at 2:43:11 pm
It depends upon the shape you're trying to wrap. Fitting to a billboard is a simple matter of corner pinning, and often motion tracking if your camera is moving. Wrapping around an object would be called texture mapping, and if you're on the CC version of After Effects, you've got Cinema 4D Lite and Cineware to help do the job.
Another option, if you're still on CS6, which I am, is to use Video Copilot's Element 3D. It's a simple matter to set a layer in your comp to be the texture (in the Element menu) and then use that texture to wrap the object in the Element interface. Do a search on "Texture mapping in after effects", and you'll see quite a few different methods, depending upon which version you're using, and which plugins and third party packages (I use 3DS Max) you have on hand.
