Motion Capture
¿Qué es Motion Capture?
Motion capture records how a real person moves and uses that data to animate a digital character, so the character inherits the natural timing and physicality of a live performance.

Cómo se compara
Motion capture records real human movement and transfers it to a digital character, producing naturalistic results quickly but requiring post-processing and retargeting. Keyframe animation is constructed entirely by an animator, offering complete creative control over timing and exaggeration but demanding significantly more time per second of finished animation.
Piénsalo como…
Motion capture is like taking a mould of a sculptor's hands as they work: the digital character inherits the shape and energy of real physical movement, rather than having that movement imagined and constructed from scratch.
Consejo pro
When using AI-powered markerless mocap tools from standard video, shoot with a clear background, consistent lighting, and the subject fully in frame throughout: the cleaner the source footage, the more accurate and usable the captured skeletal data will be.
Tipos y variaciones
- Optical motion capture uses reflective or active markers tracked by infrared cameras and remains the industry standard for high-accuracy studio production.
- Inertial motion capture uses sensor-equipped suits to record movement using accelerometers and gyroscopes, offering greater portability without requiring a controlled camera environment.
- Markerless motion capture uses computer vision, often powered by AI, to extract skeletal data from regular video footage without any specialist equipment.
- Facial capture is a specialised application that records the subtle deformations of the face for driving blend shape or bone-based facial animation systems.
- Full performance capture combines body and facial data simultaneously to capture complete character performances, as used in major film and game productions.
