It took years to develop motion capture as we know it today. By using the information obtained, the system computer will then generate a stick figure that moves exactly how the actor does. It is called the “Graphical Marionette.” For this technique, two cameras are set up to track and record the location of LED attached to the actor’s joints. To read more about rotoscoping and how it is still used today, check out my extensive article on it here.īut the first motion-tracking system was developed in the early 80’s. It is a device that projects a film on a glass panel where the artist places a paper and painstakingly draws the projected image frame by frame. This type of technique is used in video games, TV, movies, and even in the medical field.īefore it was called motion capture, it started out as an invention of Max Fleischer called the rotoscope in 1915. Motion Capture is a CGI technique that records the movements of an actor or an object which will then be transferred to a 3D character on a computer screen. Faceware has ProHD cam, fiberglass helmet with an onboard mini lightbox while the latter offers markerless capture, has video recording, and custom software. ![]() Known products are Faceware and Dynamixyz. There are also cameras that capture the same without using any markers. Head-mounted cameras have become an important part of facial capture. Both suits have magnetic immunity and are best used in fight scenes and those that involve fast movements. The only difference is that MVN Link is a Lycra suit with wired trackers while MVN Awinda is a strap-based suit with wireless trackers. ![]() MVN Link and MVN Awinda both operate with 17 sensors. It is also compatible with popular plugins such as Unity, Maya, Houdini, Blender, and MotionBuilder. It has 19 IMUs, or 9DOF as they refer to, and comes with Rokoko Studio Pro software. Probably the most popular mocap suit is the Rokoko because it is considered to be one of the best mocap suits out there. It has 32 IMUs they call “neurons” and is compatible with software such as Autodesk Maya, MotionBuilder, and Moveshelf. One of the affordable mocap suits in the market, Perception Neuron 2.0 is a full bodysuit with full hand and finger tracking. Here are some of the well-known IMU-based mocap suits: Perception Neuron 2.0 Most of the mocap suits available in the market are IMU-based. IMU has sensors with accelerometers, gyroscopes, and magnetometers for tracking. There are suits that have traditional markers or sensors to capture the full body movements while others rely on an inertial measurement unit (IMU). Mocap suits are made to be skin-tight yet breathable and comfortable and are usually plain colored.

Once the movements are recorded and transmitted into the computer, VFX artists will then “clean up” the shots for any anomalies, bumps, or jitters due to occlusion, reflections, or glitches.Īside from the mocap suit, a head-mounted gear is also essential for a full motion capture experience. A “skeleton” is generated in the computer which moves in real-time and the actions recorded will be used on a 3D character. ![]() The more cameras used for motion tracking, the more precise the outcome will be. These markers are tracked by specialized cameras where the movements are being sent to a computer using motion capture software. The more updated versions are now using sensors rather than just markers to track the movements of the actor. It is fitted to the actor which helps in properly placing the markers like dots or LEDs. To start, a mocap suit is a device that an actor wears in order to help record each move they make. We’ll also check out the characters in movies and TV shows that the mocap suit has brought to life. Let’s learn more about the magic of the mocap suit, a little bit of its history, its mechanism, and how it works. The 3D character will then move exactly how the movements were captured from the suit. How do mocap suits work? Motion capture suit or mocap suit records the real-life movements of an actor or an object and sends it to a computer program where it will be applied to a 3D character. Such technology helps in making a connection to the audience and conveys the story in a more effective way. It brings to life the characters we can only imagine in a fantasy world as it moves and strides like the real thing. Motion capture suits are probably one of the best inventions created for movies and video games.
