Motion Capture & Performance Capture
Motion capture (mocap) is a technology used to record the movement of objects or people, typically by placing sensors or markers on a subject and capturing their motions digitally. Performance capture is a more advanced form of mocap that not only tracks body movement but also records facial expressions and finger gestures, allowing for a more complete and nuanced digital recreation of an actor’s full performance, often used in films and video games.

💡 Key Takeaways
- Distinguish between motion capture and performance capture and what each technique records (body movement vs facial expressions).
- Learn how markers or sensors are placed and how captured data is translated into digital character animation.
- Understand how facial capture extends mocap to record expressions, eye movement, and lip-sync for realistic performances.
- Explore real-world applications in movies and entertainment and why mocap and performance capture enhance storytelling and production efficiency.
❓ Frequently Asked Questions
What is motion capture (mocap) in film and entertainment?
Motion capture records the movement of actors or objects using markers or sensors, then translates that motion into digital data to drive CGI characters and effects.
How does performance capture differ from standard mocap?
Performance capture extends mocap by recording body movement plus facial expressions—and often voice—to create more realistic digital performances.
What equipment is typically used for mocap and performance capture?
Markers or sensors on suits, optical/infrared cameras or tracking systems, and software to map the motion; facial capture may use specialized rigs, markers, or high-resolution cameras.
What are common uses of mocap and performance capture in movies and entertainment?
Animating CGI characters, creating digital doubles, capturing stunt performances, and enabling virtual production workflows.
