LA Noire's MotionScan technology captured on video

MotionScan, the technology that powers LA Noire's impressive facial animation system, is detailed in a new behind-the-scenes video released by Rockstar. "It's a constant close-up," actor Keith Szarabjaka explains in the video. "But it's a close-up from 360 degrees."

Sure, you'll see him and the rest of the acting crew don the usual motion capture suits, but the addition of MotionScan lets Team Bondi recreate facial performance with an accuracy previously unseen. A wide array of cameras surrounds the actor, from all sorts of angles, creating a 3D composite that can be used within the game engine.

"A big theme of this game is dishonesty and to detect when people are lying," leading star Aaron Stanton emphasizes. "You couldn't have done that in the past."
