you might be suprised here ..

Video composite with three layers: green screen, film background, and CGI. Two men are shot against green screen and composited into a background scene of a castle hall. A QuickTime clip of moving smoke is also layered into the final composite.

Flying logo consisting of pure vector graphics, animated in 3D space. For this test, 2D shapes created in a multilayered Illustrator file are moved around in a 3D environment using a camera in After Effects to achieve a fly-around effect.

Illustrative text animation incorporating layered files created in Adobe Illustrator and Photoshop. This test animates randomly sequenced 0s and 1s traveling across the screen at different rates, as well as flashing green lights. The text elements were imported into After Effects as a three-layered Illustrator file. Because these are vector graphics, they could be scaled to any resolution. After the text layers were skewed using 3D effects, lighting effects were added to give the numbers a green cast.

Virtual set using still photographs to build an entire 3D environment within After Effects. The project involves constructing a room with walls and a ceiling, then placing various graphics of pipes and gauges into the 3D space. A camera is moved through the space, giving a 3D point of view. White reports, "Here's the most render-intensive graphic in our test....Again, the PC left the Mac in the dust."
