Motion Capture: A Guide to Motion Capture Technology
What is motion capture?
Motion capture, often abbreviated as MoCap, is the technology and process by which movement of people or objects is digitally captured and reproduced in a virtual environment. This technology has become increasingly important in many industries in recent years.Status: October 2026. In practice, there are mainly three approaches: IMU suits capture body movements via sensors on the body, optical systems track markers with cameras, and markerless methods derive motion from video. The choice depends on accuracy, freedom of movement, budget, and post-processing. Motion Capture can provide movements for avatars, but is not a prerequisite for every animated or AI-generated avatar. Rokoko Smartsuit Pro II · Rokoko Vision
Historical Development of Motion Capture:
The origins of motion capture technology date back to the early 20th century. As early as the 1910s, animation pioneer Max Fleischer experimented with so-called rotoscoping. In this process, real movements were filmed and redrawn frame by frame to make animations appear more natural. This method is considered a precursor to modern motion capture techniques. In the 1970s, the first experiments with motion capture sensors began. With technological advancements in the 1990s, optical motion capture systems with markers were developed, which were particularly used in the film industry. A well-known example is the film „The Lord of the Rings“, in which the character Gollum was brought to life using motion capture (played by Andy Serkis). Today, motion capture made possible by modern technologies such as inertial sensors, markerless systems, and AI-assisted capture enables highly precise animations in real time. Technological progress has significantly expanded the application possibilities – from Film and Gaming including medicine and robotics.For businesses: We also use motion capture in corporate projects, for instance for credible digital trainers in virtual training or for AI avatars in virtual reality. An application for this is AI-based VR training.
- Film and TelevisionIn the film and television industry, MoCap is used to generate realistic movements for CGI characters. Well-known examples include Gollum from „The Lord of the Rings“ or the Na'vi from „Avatar.“.
- Video gamesIn game development, MoCap helps create lifelike movements for game characters, offering players a more immersive experience.
- Virtual Reality: In VR training, recorded movements can be transferred to avatars. For live animated avatars, a real-time workflow with appropriate retargeting is required in addition.
- Health and SportIn the healthcare sector, MoCap is used for analyzing human gait and for rehabilitating patients after injuries. Athletes also use it to refine their technique.
- MilitaryTogether with virtual reality, MoCap enables realistic simulations for training scenarios.
Various motion capture methods:
An overview
- Visual - PassiveOne of the oldest and still widely used forms of motion capture is the marker-based method. In this method, special markers, usually reflective spheres or anchor points, are placed on the performer's body. Cameras in the recording studio track these markers, thus capturing precise movement data. Marker-based motion capture offers precise capture of movements and enables a detailed replication of human anatomy. However, it requires attaching markers to the body, which takes time and effort and can restrict the actors' freedom of movement.
-
- Optically activeHere, small lights emit signals that are recorded by cameras. Some advanced motion capture systems, such as the one from OptiTrack Use this technique.
-
- Key solutions with video analysis / without markersModern AI algorithms and specialized motion capture software can now capture movements directly from video recordings without the need for markers. This requires either multiple simultaneously recorded videos of a movement, or even just a single view. The more cameras that record the scene simultaneously, the more accurately artificial intelligence can extract motion data from the videos. We can expect this technology to gain importance in the future, as AI solutions are rapidly evolving. Examples of products in this area are MoveAI https://www.move.ai/ oder Radical. Even Rokoko, which is actually known for motion capture suits like the Smart Suit Pro, has additionally provided an AI solution for its paying customers.
-
- Inertial Measurement Units – IMUsThis method uses sensors attached to the body that record movements in real-time. Products such as Rokoko's SmartSuit Pro and Perception Neuron Noitom products are popular examples of this technology. This inertial motion capture technology offers a wireless and portable solution, as no additional cameras or markers are needed. Users can simply put on the suits and record motion data in real-time, which can then be used to create animations or control virtual characters. A potential disadvantage of IMUs (Inertial Measurement Units) in motion capture lies in their limited accuracy with prolonged use. IMUs are based on the measurement of acceleration and rotation and can therefore be susceptible to drift, which can lead to a gradual accumulation of errors. This can result in the captured motion data becoming less accurate over time and requiring regular calibration or correction. IMU-based motion capture systems include, for example,.

Advantages and Challenges
Advantages of Motion Capture:
- Low Latency: Motion capture enables the immediate conversion of real movements into digital motion data.
- Accuracy: MoCap delivers accurate and realistic data depending on the equipment.
- Motion capture drastically reduces the cost and time required to create character animations.
Disadvantages of motion capture:
- Most motion capture technologies require specialized software and hardware: Capturing and processing MoCap data typically needs special equipment and software.
- Costs: High-quality MoCap systems can be expensive. Cheaper systems are usually significantly less precise than the expensive systems used in major film productions.
Step by step: How motion capture works
PreparationThe actors or objects are equipped with the necessary markers or sensors.
RecordingThe movements are recorded with special cameras or sensors.
Data processingThe recorded motion data is then transferred into a digital format that can be used in software such as Maya, 3ds Max, or Blender. It is usually necessary to eliminate errors and inaccuracies that occurred during the capture process. This process can be quite time-consuming, depending on the quality of the source data. This process is called „cleaning.“ Once the data is cleaned, it can be loaded onto a 3D character model in the chosen 3D animation software.
Investment in Motion Capture: What does it really cost?
The cost of motion capture can vary depending on the required quality and complexity of the system. Entry-level systems like Rokoko and Perception Neuron can be available for around 3000 Euros, while professional systems can cost six figures.
The quality of low-priced systems is constantly improving, making impressive results possible even with a 3000 Euro system.

The History of Motion Capture Technology
The idea of motion capture dates back to the 1920s when the technology was first used in the film industry. However, motion capture was very limited at the time and could only capture simple movements. In the 1970s, the first marker-based motion capture systems were developed, which allowed for more accurate capture of movements. Nowadays, there are various types of motion capture systems, including optical, magnetic, and inertial systems.
Facial Motion Capture aka Performance Capture:
In addition to capturing body movements, a character's facial expressions and gestures are also of great importance. Facial motion capture focuses specifically on recording and transmitting facial movements. This involves either marker-based or markerless methods to capture the smallest facial expressions and emotions. A remarkable example of the capabilities of face capturing is the portrayal of Gollum in „The Lord of the Rings“ film trilogy. The character's subtle facial features and emotions were depicted realistically and credibly, which was largely made possible by face capturing technology. Actor Andy Serkis, who portrayed Gollum, not only provided the voice and physical movements for the character but also the facial movements. However, there are also increasingly affordable face capture solutions available, mostly using just an iPhone to record facial movements. For example, iClone, Rokoko and Unreal Engine's MetaHuman Animator. This way, face capture has become a real option for small studios to create more lifelike 3D characters.
Tips for Successful Motion Capture Sessions
A successful motion capture session requires careful planning and preparation, as well as clear communication with the actors or animals. It is important for actors to wear comfortable clothing and avoid accessories that could interfere with motion capture. The motion capture session should also take place in a well-lit room for optimal results. Conduct calibration and test runs before beginning actual recording. Check the functionality of the equipment and ensure that movements are captured and transmitted correctly.
Popular Motion Capture Software and Tools
There are many motion capture software and tools on the market. Some of the most popular ones are Autodesk MotionBuilder, Rokoko, IClone, Vicon, OptiTrack and Xsens. These software and tools offer a variety of functions to create precise animations and visual effects.
Case studies of successful motion capture content
Many successful motion capture contents have been created across various industries. The film industry uses motion capture to create realistic animations of animals and monsters. Video game development also uses it to create realistic character animations and athlete movements. In advertising, motion capture has been used to bring products to life.
We from Design for real use motion capture for various projects, such as VR Diversity Workshop Just a moment., or also the WebAR Halder Hammer Showcase, in which we used technology to give the 3D characters lifelike animations.
The future of motion capture technology
Motion capture is a rapidly evolving technology that is expanding into more and more industries. In the future, the technology will become increasingly powerful, capable of creating even more realistic animations and visual effects. We anticipate that artificial intelligence will revolutionize this technology, and in the future, specialized hardware for mocap recordings will hardly be needed anymore. Move.Ai already shows today how powerful and simple Artificial Intelligence Mocap solutions can be. We will probably be able to record high-level motion capture simply with a mobile phone in the future. The conversion into motion data will be handled in the cloud with the help of Artificial Intelligence.
Conclusion
