As such, we will refer to FX as the traditional approaches to special effects through the physical means, while CGI will refer to the visual effects of FX through digital means. Despite the obvious dominance of CGI, traditional special effects methods are still prominent in today’s age, as you cannot exactly replicate human behaviour in the most accurate way with computer graphics.

From the above statement, one must mention the obvious solution to this dilemma, and that is the application of motion capture or “mocap” for short. This is in between physical special effects and digital computer generated images and is a bridge to develop realism in films. Essentially, motion capture is the process in which exact human movement is captured and processed digitally and applied to computer graphics. Furthermore, facial motion capture is becoming more prominent to get the most accurate readings of facial expressions.
