Motion tracking is an affordable option even in these tough financial times. In the past Chroma or green screen technology was something reserved only for big-budget Hollywood production houses who could afford to use it, but with recent advances in technology, Chroma has now become cheaper and more accessible than ever before. Now almost any production company that has a green wall and the right lighting can make use of this to film a moving person and later replace the green background with a real or computer generated environment without having to bring in costly optical motion devices. Although chroma has opened up a wealth of opportunities for production companies it has, however, had its limitations as until recently it was imperative that the camera remain still throughout the process. When the green screen was replaced with another background it was nearly impossible to manually adjust the environment in relation to the person in the foreground for a realistic result if the camera was moving. Understanding the limitations of this medium, we have found a way to work around this to create moving shots that look realistic. We place tracking points in the Chroma studio and once the footage is captured, it is taken through an application where a motion algorithm is calculated. In post-production when the green is replaced with the 3D environment, the computer reads these algorithms and makes calculations in reference to the tracking points to create an environment that …
