Motion-capture acting in the context of Kratos (God of War)

Motion capture (sometimes referred as mocap or mo-cap, for short) is the process of recording high-resolution movement of objects or people into a computer system. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots.

In films, television shows and video games, motion capture 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.

Voice acting is the art of performing a character or providing information to an audience with one's voice. Performers are often called voice actors/actresses in addition to other names. Examples of voice work include animated, off-stage, off-screen, or non-visible characters in various works such as films, dubbed foreign films, television shows, video games, animation, documentaries, commercials, audiobooks, radio dramas and comedies, amusement rides, theater productions, puppet shows, and audio games.

The role of a voice actor may involve singing, most often when playing a fictional character, although a separate performer is sometimes enlisted as the character's singing voice. A voice actor may also simultaneously undertake motion-capture acting. Non-fictional voice acting is heard through pre-recorded and automated announcements that are a part of everyday modern life in areas such as stores, elevators, waiting rooms, and public transport. Voice acting is recognized as a specialized dramatic profession in the United Kingdom, primarily due to BBC Radio's long and storied history of producing radio dramas.
