First film to use motion capture suit12/31/2023 ![]() ![]() Moving onto the cameras, including the head-mounted camera, which, in some ways, it is kind of like the old wire construction headgear to get your teeth straight. Image from 20th Century Studios via Youtube But here are some more details, including what kind of software and hardware options there are: So by now, you've probably already picked up on some of the technology you need to use motion capture animation. Technology Needed for Motion Capture Animation However, it's not as accurate as the other methods mentioned above and is preferred by larger companies for minimizing retakes for fuller scenes. Rather the acting is recorded by a bunch of depth-sensitive cameras over a gridded floor.Įvery possible angle is recorded, analyzed, and turned into animation software that linked software can make the magic of the motions appear on the object/character. This isn't the most practical option because, of course, the LEDs need a power source which means some kind of battery/charge, and well, it just gets complicated and risky.įor our fourth motion capture animation method, the actors are saved from wearing suits. Basically, making light rather than reflecting, the motion is captured by cameras that specifically record the lights' movements. With this motion capture method, the actors are in the same suits, except they have LED suit markers rather than retroreflective markers. In this case, impressive realistic content comes at a hefty price. Even then, only for the most accurate content needed. ![]() Optical-Passive motion capture is mostly used by big guns in animation and film. You can read more about rotoscoping here. ![]() This motion capture animation method actually dates way back to the method rotoscoping with Fleischer, with its techniques being fine-tuned with technology in the past years. As the actor moves, the retroreflective markers on the suit reflect from the nearby camera lenses, and that reflected light is tracked by infrared cameras, producing the motions and emotions for the further digitalization of the character. This method finds actors kitted out with super tight suits which have retroreflective markers on them. The most common sensors used in IMUs are gyroscopes, magnetometers, and accelerometers. It records movement through IMUs (inertial measurement units), which contain sensors to measure rotational rates. This technique doesn’t necessarily need cameras to operate. Accelerometer: yup, you guessed it - this device measures an object or body’s accelerating movement or vibration.Magnetometer: it measures the first part of its name - magnetic forces.Gyroscope: this tool helps to pick up when an object is deviating off of its desired orientation - the tool either uses a wheel that spins super fast or a beam of light circulating.IMUs (inertial measurement units): it’s the following measurement tools all in action together.Inertia: Do you know how you can make your car stop or how you can control the direction it’s going in? That kind of illustrates what inertia is - keeping anything moving straight without changing direction or keeping something from changing to a position is the force called inertia.To really break this down, we’re first going to give some definitions before hurling a bunch of big words at you: This method is probably the most cost-effective option, especially if you’re still getting to know motion capture animation or if you're still getting your business up and running. We got some of our understanding from “ What is Motion Capture, and How Does it Work in 2022?” and What is motion capture and how does it work? Understanding what they are will further help you understand why animators use motion capture for animation. You basically have four different types of capturing motion, each with its pros and cons. What are the Different Techniques of Motion Capture Animation And all of this helps to generate a realistic and believable character. Motion capture animation literally maps out anything you as an animator feel is important to capture - and then continues to map it out as the figure moves.Īfter the “mapping” is done, technology is used to apply the motion to the computer-generated imagery (CGI) character or figure. Almost like a very, very detailed stick-man - like very detailed. You can think of it as mapping out the character down to its tiniest detail. It’s not really about the actual footage as it is about the movement, the motions, and the emotions. In short, mo-cap is pretty much what it’s called - capturing the motions of the person/item/character being filmed and applying the captured motion to the animated character.
