Pre-visualization technique specifically for planning and choreographing stunt sequences—uses 3D animation, motion capture, or live-action reference footage to design complex action before shooting.
What is Stuntvis?
Stuntvis (Stunt Visualization) is a specialized pre-visualization technique for planning stunt sequences. It allows for the design of complex action before shooting to optimize timing, camera work, and safety.
