Motion capture technology helps a director achieve realistic human motion in filmmaking. In real-time, a director can observe many details recorded by multiple cameras that track devices pinned to optimal points of the body.

“We’re using high-speed, high-resolution cameras at 120 frames per second,” says Brian Nilles, chief strategy officer at OptiTrack — a company that creates software for motion-capture. OptiTrack was among the many exhibitors on Aug. 12 at the 2015 SIGGRAPH conference in Los Angeles that demonstrated the latest in filmmaking technology.

“We’re finding the position of their bodies and their limbs in space,” Nilles adds. “We take that information and turn that into a digital skeleton. That’s the way character animation is done for realistic motion for filmmaking.”
