From green screen to XR screen, what is changing?
When using traditional green screen studios to shoot movies, actors perform in front of the screen without physical objects, pictures, or a sense of immersion. This performance environment requires higher performance skills from the actors. After the shooting is completed, the technicians behind the scenes will perform a comprehensive cutout of the film, remove the background color, and replace the corresponding application background. The whole process is time-consuming and laborious.
With the advent of XR technology, film and television shooting can use more convenient XR solutions. From VR virtual reality, AR augmented reality, MR mixed reality to today’s XR extended reality, virtual scenes have repeatedly made breakthroughs and innovations. XR cleverly combines the fortunes of the first three and uses hardware equipment and other technical means to create a realistic and immersive environment experience for users.
The first application scenario of XR is virtual studio shooting. The combination of LED screen and XR technology can bring users a super immersive experience, which is conducive to actors immersing themselves in a colorful and realistic spatial environment when performing. Performing in a spatial environment created by XR technology is conducive to improving the overall shooting progress. In addition, previous film shooting, especially blockbuster production, was shot with a green screen as the background, and the whole film was completed by cutting out images in the later stage. The post-production of images often takes up a lot of production time and production costs. Through XR solutions, work efficiency can be improved and work costs can be reduced.
LED light sources can provide realistic light and shadow effects and delicate color performance, making the shooting picture more perfect. From the perspective of film production, using LED screens as backgrounds can speed up the efficiency of film special effects production and reduce the total cost. Therefore, the initial filming of virtual movies and TV series adopted the “LED left screen + right screen + ground screen” method. The actors were wrapped in a studio made up of three LED screens. However, due to the large seams of conventional spliced screens, bright and dark lines will appear during the shooting process, affecting the quality of the film and the viewing effect is not good.
The key to virtual shooting lies in the LED display screen. If conventional LED screens are used for splicing in XR solutions, there will be large gaps between the splicing and the appearance of bright and dark lines. If LED flexible screens are integrated into XR solutions, the entire screen transitions smoothly, perfectly solving the problems of splicing and bright and dark lines, and the visual effects presented by the curved screen are more three-dimensional and full. Whether from the perspective of actors or the audience, Meiyad LED flexible screens are an excellent choice. Meiyad will achieve the ultimate in XR solutions and show users better shooting effects.
Through the rendering engine and media server, the dual-engine technology of the picture is realized, the AR foreground and background pictures are rendered, the virtual engine is run, the rendering instructions of the synthesis server are received and rendered in real time, and the spatial correction, color correction and synchronous calibration are completed, which can improve the brightness and color of the pixels, accurately present the picture, and ensure that the rendering engine outputs the picture delicate and realistic. The unique 4K@60Hz 10bit 4:4:4 comprehensive solution conforms to the PQ curve and accurately restores the brilliance of the HDR video source.
The XP solution can preset different display effects before the formal shooting, and can easily switch to different tone styles with one click during work, and can be flexibly applied. It supports the output of different camera positions and multiple different materials at the same time in one shooting, and supports the insertion of background materials from different angles in the same scene, and outputs multi-angle shooting pictures at the same time. In addition, through the ultra-high-definition 8K 1G XR display solution, it supports 3D LUT and other color adjustment tools, which are easier and more flexible to use, making the color richer, more saturated, more accurate, and more detailed, creating a more immersive experience.
XR will be integrated with the real world in the future
With the popularization of 5G network applications, the maturity of 8K display industry, the popularity of the metaverse concept, and the official establishment of the XR department by Tencent, a series of related information indicate that XR technology will be integrated with the real world in the future. As XR terminal devices begin to scale up, there are signs of exploring the market, and XR solutions have been successfully applied in film and television shooting, live events, news broadcasts, game entertainment, medical applications, military, aerospace and other industries. We have reason to believe that XR will be one of the advanced technologies that will be integrated with the real world in the future.
