In 2020, the rise of XR extension technology has brought about a new revolution in the film and television industry. Until now, LED virtual production based on LED background wall has become a hot topic in the industry. The combination of XR (Extend Reality) technology and LED display has built a bridge between virtual and reality, and has made great achievements in the field of virtual film and television production.
What is LED studio virtual production? LED Studio Virtual Production is a comprehensive solution, tool and approach. We define LED virtual production as "real-time digital production". In actual use, LED virtual production can be divided into two types of applications: "VP studio" and "XR extended studio".
VP studio is a new type of film and television shooting method. More used for filming and TV series. It enables film and television producers to replace green screens with LED screens and display real-time backgrounds and visual effects directly on the set. The advantages of VP studio shooting can be reflected in many aspects: 1. The shooting space is free, and the shooting of various scenes can be completed in the indoor studio. Whether it is a forest, grassland, snow-capped mountains, it can be created in real time using the rendering engine, which greatly reduces the cost of framing and shooting.
2. The whole production process is simplified. "What you see is what you get", during the shooting process, the producer can view the desired shot on the screen in time. Scene content and narrative space can be modified and adjusted in real time. Greatly improve the efficiency of changing scenery and changing scenery.
3.Immersion of the performance space. Actors can perform in the immersive space and experience it directly. The actor's performance is more real and natural. At the same time, the light source of the LED display provides real light and shadow effects and delicate color performance lighting for the scene, and the shooting effect is more realistic and perfect, which greatly improves the overall quality of the film.
4.Shorten the return on investment cycle. Compared with the traditional time-consuming and labor-intensive film shooting process, virtual shooting production is highly efficient and the cycle is greatly reduced. The release of the film can be realized faster, the remuneration of the actors and the expenses of the staff can be saved, and the shooting cost can be greatly reduced. This virtual production of movies based on LED background walls is considered a huge development in film production, providing a new impetus for the future of the film and television industry.
XR extended shooting refers to the use of visual interaction technology. Through the production server, the real and the virtual are combined, and the LED display screen is used to create a virtual environment for human-computer interaction. Brings the "immersion" of seamless transition between the virtual world and the real world to the audience. The XR Extended Studio can be used for live webcasts, live TV broadcasts, virtual concerts, virtual evening parties and commercial shooting. XR extended studio shooting can expand virtual content beyond the LED stage, superimpose virtual and reality in real time, and enhance the audience's sense of visual impact and artistic creativity. Let content creators create infinite possibilities in a limited space and pursue endless visual experience.
In the virtual production of LED studio, the entire shooting process of "VP Studio" and "XR Extended Studio" is roughly the same, which is divided into four parts: pre-preparation, pre-production, on-site production, and post-production.
The biggest difference between VP film and television production and traditional film production methods lies in the changes in the process, and the most important feature is "post-preparation". VP film and television production moves the 3D asset production and other links in traditional visual effect films before the actual filming of the film. The virtual content produced in the pre-production can be directly used for the in-camera visual effects shooting, while the post-production links such as rendering and synthesis are moved to the shooting site, and the composite picture is completed in real time, which greatly reduces the workload of post-production and improves the production efficiency. In the early stages of video shooting, VFX artists use real-time rendering engines and virtual production systems to create 3D digital assets. Next, use the seamless splicing LED display with high display performance as the background wall to build an LED stage in the studio. The pre-production 3D rendering scene is loaded onto the LED background wall through the XR virtual server to create an immersive virtual scene with high picture quality. Then use accurate camera tracking system and object position tracking and positioning technology to track and shoot the object. After the final shooting is completed, the captured material is sent back to the XR virtual server through a specific protocol (Free-D) for viewing and editing.
