This Lexus spot required ArsenalFX to clean up a good deal of ground seen on the race track, as the road whips past the speeding car. This work spanned crane shots, curving roads, and camera zooms. Conventional 2D tracking techniques would not have been able to provide this outcome without extensive hand tracking and an odd-looking perspective. In order to accomplish this road cleanup, ArsenalFX used 3D tracking software (Boujou) to create a 3D camera that would match the live action camera which was used to shoot the original footage. These sequences were then brought into a 3D program (Maya) where the ground was modeled as geometry. Simply using a flat plane was not enough -- ArsenalFX needed to match the curvature of the ground. This was all exported as an FBX and imported into Flame. Once inside Flame, the ArsenalFX team painted numerous clean still frames of the race track. These were then projected onto the ground geometry and tracked in, via the 3D camera. Ultimately, a seamless and camera corrected fix resulted in a faster process, and in superior quality of the finished picture.
