The Video was shot @ 30 Frames to give a more "Consumer -Cam" look. The Building was modeled in 3D Max. The explosions were created using FumeFx (in MAX) and the Particles were done using RayFire (also in Max).

The Composite was done in After Effects. There was some additional 2D smoke & Fire which was put on Cards in 3D space. Since I used Boujou to Track the camera Data, I was able to import the 3D camera into After Effects. This made the placement of any Cards in the composite extremely accurate. It also eliminated the need of using After Effect's 2D tracker.
The 2D elements were from Video Copilot's Action Stock footage collection.
