Motion Capture is a state of the art technique used to record actors who are also known as mocaps. The direct purpose is for the actors to provide their movements for video game characters. Motion Capture was first used in Mortal Kombat 4. It then became common afterward.
Actors wear dark suits and specialized hats. Electronic beads cover their faces and other areas of their bodies. Lamps emit orange lights to enable recording. Actors will follow a script or set of instructions. During the same time, the recorded movements will appear on a nearby screen. Actors will either work together or by themselves. At the very least, one actor will portray everyone. A person can enter an area where Motion Capture is taking place without wearing the specialized suit and hat. However, their movements will not be recorded.
- The character Mokap (acronym of motion capture, with a K as per Mortal Kombat fashion) is a homage to Carlos Pesina, who provided his movements for various characters in the Mortal Kombat games.
- Prior to Mortal Kombat 4, characters were based on the filming of actors in costumes. They would act in front of a blue/green screen. The filming was then inserted into a computer for editing. This process was called digitization.
- Objects can also be captured. In fact, weapons were captured for some of the older Mortal Kombat games.
- Motion Capture is also often used for other projects such as movie design.
