Reflections onto “wet floors” is all the rage these days in design (e.g. see Apple). True reflections are rendered in 3D software like Maxon’s 4D or the open-source Blender–After Effects isn’t a 3D program (although using the CS4 suite is changing that slightly) so you can’t get the same results in the compositing program. That said, there are a lot of work arounds that copy, flip and blur footage elements to get faux reflections. Art Beats has a great tutorial written by Chris & Trish Meyer of Crish Design (http://www.cybmotion.com) to add the faux reflection effect to your digital signage videos.
