Motion capture (Mo-cap for short) is the process of recording the movement of objects or people.

it refers to recording actions of human actors, and using that information to animate digital character models in 2D or 3D computer animation.

When it includes face and fingers or captures subtle expressions, it is often referred
to as performance capture.
In many fields, motion capture is sometimes called motion tracking, but in filmmaking and games, motion tracking usually refers more to match moving.
