LED for Virtual Stages and Film Studios
Are we to witness the end of the green-screen era? A silent revolution is taking place on film and TV sets, virtual production is enabling productions to create immersive and dynamic sets and backgrounds, based on simple LED panels instead of elaborate and costly set designs.
LED panels prove to be the ideal solution and canvas to portray set and backgrounds created in virtual reality. Thereby creating maximum flexibility for the production teams to make last-minute set changes or slight alterations and comforting actors in a setting that is both real and immersive, enhancing their performance in comparison to performing against a green screen.
Virtual Productions & xR Stages
Event organizers are looking to invest in hybrid event platforms to position their businesses, bringing people together in new and engaging ways.
Data from the market is backing this up, smaller meetings and meetings with virtual delegates have to fill the gap, The change to being able to organize normal events will be very gradual. ROE Visual, a preferred supplier for most companies engaging in this fast-evolving technology, rises to the challenge.
A similar technology is used to create immersive video environments for broadcast. Replacing the traditional green screen element of a virtual studio allows the presenters and audience to see and interact with the content around them. This ground-breaking technology is already having a huge influence on how broadcasts are delivered across the globe.
LED in Film & Broadcast
This new and groundbreaking virtual production methodology is based on shooting films and series on a stage surrounded by massive LED walls displaying dynamic digital sets, with the ability to react to and manipulate this digital content in real time during live production. Using an LED wall, floor, and optional ceiling, the set-up is scalable to any desired space. Using a virtual background cannot only reduce the costs of on-location shoots and post-production time, but it also can boost the performance of the actors involved.
Virtual productions: How does it work
By building a massive LED video wall, you can create dynamic digital sets that replace the traditional greenscreens. Adding a LED ceiling or LED floor you can even further enhance the dynamic digital environment. Making it as immersive as you want. LED ceilings also provide a responsive and stable light source for your set, offering an alternative towards regular TV and film lights. Creating the right canvas for this type of application is not just building any LED screen. It’s where the LED panel, processing and camera work together, complement and strengthen each other that real stunning results are achieved. The pixels on the LED wall are driven in real-time by the game engine, this requires sufficient driver IC to do a proper job.
This revolution started when Epic Games partnered with Lux Machina, Magnopus, Profile Studios, Quixel, ARRI, and DP Matt Workman to try out the capabilities of the latest virtual production toolset in Unreal Engine 4.23 for this specific application. When the right people, tools and materials come together, you can create thrilling and innovative filmmaking.
Create the impossible
Combine hidden Chromakey, hidden Tracking, and Multiple Source video feeds into a single production frame. You choose which elements are visible to the human eye and which are visible only to the camera.

When using a live LED wall in place of a static green screen, you as a director gain additional benefits such as increased accuracy and control over framing and lighting. Instead of requesting your cinematographer to make an educated guess about virtual elements in the frame, you’ll actually be able to frame them directly in the viewfinder, and the cinematographer can light scenes according to their training and expertise. Your actors will know what they’re looking at and be able to modulate their performances to match the action instead of suffering from green-screen fatigue and disorientation.

Replacing the traditional green screen element of a virtual studio allows the presenters and audience to see and interact with the content around them. This ground-breaking technology is already having a huge influence on how broadcasts are delivered across the globe.
“If the production involves a real-time LED wall, as a DP you’ll find plenty of new options for control over the image. Turnaround becomes far less time-consuming because rather than having to physically move the crew, actors, set pieces, and so on, you can just rotate the background scenery on the screen and be able to reset for turnaround in moments instead of hours. This also means you can hold and control the time of day to any specific mood and color temperature you desire.”
