Real-time composing in virtual production enables filmmakers to blend live-action and computer-generated elements in real time. With compositing built directly into the engine, green-screened scenes can be easily visualized and combined with computer-generated imagery. This eliminates the need for post-processing, as footage can be captured and edited live. Our technology, combined with virtual cameras and motion capture, allows for more efficient and creative filmmaking, as changes can be made on the fly and visual effects can be seamlessly integrated.
