Motion capture video games

Motion capture is often used in video games such as sports games and many more. Motion capturing techniques are very effective, but the computer processing needs much human intervention, and if there is any error in the data, you can find it more effective to re-shoot the whole scene rather than correct the data. However, motion capture technology is so much more effective and realistic than traditional techniques, and ultimately less time consuming, that its future looks assured in movies and in video games.

In motion capture sessions, movements of one or more actors are sampled many times per second, early techniques used images from multiple cameras and calculate 3D positions, motion capture often records only the movements of the actor, not his or her visual appearance.

Camera movements can also be motion captured so that a virtual camera in the scene will pan, tilt, or dolly around the stage driven by a camera operator while the actor is performing, and the motion capture system can capture the camera and props as well as the actor's performance.

 This allows the computer-generated characters, images and sets to have the same perspective as the video images from the camera. A computer processes the data and displays the movements of the actor, providing the desired camera positions in terms of objects in the set. Retroactively obtaining camera movement data from the captured footage is known as match moving or camera tracking. The first picture below, the suit is called a spandex suit.

This is an example of motion capture.
