Real-time compositing

Definition

Real-time compositing is the process of combining multiple visual elements from different sources into a single cohesive image or sequence, with the ability to do so instantly during live action or performance. This technique allows filmmakers to create seamless integration of live footage with computer-generated graphics, visual effects, and other digital elements, making it a vital part of modern filmmaking and performance art. The ability to visualize these elements in real-time enhances creative decision-making and provides immediate feedback during production.
