Beginner's Guide to Virtual Production Platforms
Virtual production is a rapidly evolving technique that merges the physical and digital worlds in real time; it fundamentally transforms how films, television shows, and media content are created and delivered to the end user. By integrating cutting-edge technologies like real-time rendering engines, LED screens, and motion capture systems, virtual production allows filmmakers to visualize and interact with computer-generated environments during filming.
This approach provides greater creative control, shortens production times, and reduces overall costs. It is an increasingly attractive choice for large studios that want to avoid cost overruns and independent creators who usually work on tighter budgets.
What Is Virtual Production?
Large LED walls are at the heart of virtual production, often called "LED volumes"or “virtual production stages,” which display high-resolution, computer-generated backgrounds onto LED walls. LED volumes allow filmmakers to visualize and adjust scenes in real-time, offering unparalleled flexibility in set design and cinematography while allowing actors and directors to interact with the virtual environment during filming, enhancing their performance and creative decision-making.
These backgrounds are rendered in real-time using game engines like Unreal Engine. They respond dynamically to camera movements and lighting changes, allowing filmmakers to capture their final shots in-camera.
This methodology has become a game-changer in modern media production. It first garnered widespread attention with its use in The Mandalorian, a Disney+ series showcasing vast, otherworldly settings created through Unreal Engine and displayed on LED walls. Using virtual production, scenes that looked like they were filmed in exotic or alien locations could be shot without leaving the soundstage. The result was a more controlled, efficient, and cost-effective production process.

What Are Virtual Production Platforms?
Virtual production platforms are integrated software and hardware ecosystems enabling the real-time blending of virtual elements with live-action footage. These platforms include a variety of components working together:
- Real-Time Rendering Engines: Software such as Unreal Engine or Unity can instantly generate high-quality 3D graphics.
- LED Volumes or Green Screens: Large-scale LED walls or traditional green screens that act as dynamic and free-flow backdrops.
- Camera Tracking Systems: Tools that track the movement and position of cameras to align the virtual environment’s perspective accurately.
- Motion Capture Systems: Equipment that records actors’ movements and facial expressions, allowing creators to animate digital characters or avatars.
The main difference between virtual production and traditional production is immediacy. Traditional production often requires a lengthy post-production phase to composite effects and adjust scenes. Virtual production, on the other hand, enables directors, cinematographers, and visual effects teams to collaborate on a real-time version of the final product and make instant creative decisions and changes.
Virtual production platforms streamline the entire production pipeline by allowing visual effects to be rendered live, saving time and money by reducing back-and-forth between departments. Additionally, virtual production platforms allow for better planning and visualization during pre-production, improved performance capture during production, and fewer surprises during post-production.
The benefits are numerous: faster turnaround times, cost savings from fewer location shoots and reshoots, and an overall smoother workflow. It also enhances storytelling by allowing greater experimentation and immediate feedback.
Key Technologies Involved in Virtual Production
Real-Time Rendering Engines
At the heart of virtual production are real-time rendering engines. Unreal Engine and Unity are two of the most popular platforms that enable instant rendering of complex 3D environments. These engines allow for high-resolution textures, dynamic lighting, and advanced physics simulations, all of which contribute to a more immersive experience. Because they render scenes instantaneously, directors and cinematographers can immediately adjust lighting, angles, and environmental details while the scene is filmed.
Motion Capture Systems
Motion capture technology records actors' movements to animate digital characters in real time. These systems use specialized suits fitted with sensors that track body movement and facial expressions. The captured data is then applied to virtual avatars or CGI characters. This allows actors to see how their digital counterparts perform in the scene, helping to synchronize performances and enhance the realism of the final footage.
Augmented Reality (AR) and Virtual Reality (VR) Technologies
AR and VR add immersive elements to the virtual production process. In pre-production, VR can be used to scout virtual sets, rehearse scenes, or design environments. AR can project interactive elements into the physical set during production, allowing actors and directors to interact with virtual props or characters. These technologies help visualize scenes more effectively, improving performance and storytelling.
Benefits of Using Virtual Production Platforms
Creative Flexibility
Virtual production opens the door to nearly limitless creative possibilities. The availability of physical locations or set designs no longer limits directors. Does the moviemaker want to shoot a scene on a distant planet or in a historical setting such as the Dark Ages or ancient Egypt? Virtual production makes it possible to do so. This flexibility allows filmmakers to experiment with different looks, lighting setups, and camera movements on the fly. The ability to see and modify scenes in real time encourages spontaneous creative decisions, which can lead to more compelling storytelling.
Cost and Time Efficiency
One of the most compelling reasons to adopt virtual production is the significant savings in time and budget. Traditional filmmaking often involves expensive travel, work visas when filming in different countries, location and construction permits, long setup times, delays, cost overruns due to unforeseen occurrences, including inclement weather, and extensive post-production work. With virtual production, all of this can be minimized or eliminated. Virtual sets are reusable and can be altered instantly, reducing the need for reshoots or additional shoots. The real-time rendering process also means many visual effects are completed during filming, shortening the post-production timeline.
Enhanced Collaboration
Virtual production promotes a more collaborative working environment. Since everyone involved in the production—directors, producers, set designers, cinematographers, and visual effects artists—can see the final result as it’s being created, they can provide input and make changes in real time. Remote collaboration is also easier, as cloud-based tools and real-time engines allow teams across different locations to work simultaneously on the same scenes. This leads to more cohesive results and a smoother production process overall.
