LED WALL VIRTUAL PRODUCTION
LED Wall Virtual Production which is a new film-making technology emerged recently, is attracting more attentions. It is an innovative and revolutionary concept that combines XR, the most advanced film production techniques, LED display wall, and so on. LED walls for virtual production are on their way to changing Hollywood and whole filmdoom.
Today, we will take you to have insight of the virtual production LED wall from both technological level and business levels. We will tell you the principles and structure of it, and what are the points you should pay attention to so as to increase your potential profits. We all know, for traditional film production, the most popular ways of creating special effects involve green screens and projection. However, they often need complex and time-consuming post-production. For example, the perspective effect, which is one of the most important parts of adding the sense of reality to the films can not be met by green screens and projection due to their limitations of fixed background and will cost significant labor and expenditure to make the film cater to the demand.
And there may be some unwanted and unexpected situations happening due to the disunion between shooting and post-production. For instance, the lighting of the shooting site may not meet the requirements of post-production. One of the common situations happens when the lighting engineers mistake the lighting, for example, there is no correct reflect the light of props such as swords and helmets, thus resulting in huge tasks for the post-production staff and a sense of unreality.
Under such circumstances, people research and develop a combination of technologies lets filmmakers can replace the traditional green screens with LED walls to facilitate the shooting, reduce the unnecessary post production, add more realism such as the real-time perspective shift and appropriate reflect light, etc. In a word, these functions can solve the pain points of traditional film shooting, and improve the whole visual effect while decrease the expanses on special effect producing and unnecessary redundancy.

LED virtual production technology combines the technologies of a large wraparound LED wall, game engine (UE4 game engine), and camera with a tracking device on top. Next, we will explain these components separately.
First, the game engine, often the UE4 game engine, is a kind of software that can create special effects which will be displayed on the LED display screen. Second, LED video wall is the soul of this new technology. The virtual production LED display will take the burden of the background and display the special effects. Third, the camera with a tracking device. This kind of camera can capture the relative location of the screen, thus sending the tracking data to the game engine, and the real-time content out of the game engine will be displayed on the LED screen immediately.
In this situation, the physical actors in the real world can interact with the contents shown on the LED display wall, and the right perspective can be achieved immediately while do not need to adjust and create a complex effect during the post-production. The background will look like a three-dimensional space that can be zoomed, tilted and traveled through but not the traditional simple flat backdrop. Now, you may have already understood the basic three elements of unreal engine LED wall are LED display wall, game engine and camera with tracking device. Each of them consists the irreplaceable intelligent and high-tech new filming method.
