Since 2022, the XR virtual production studio, which has been hotly hyped, has been predicted by all parties because of its feasibility, simplicity and low cost.
Feasibility
XR can use camera tracking and real-time image rendering technology to make the virtual scene displayed on the large screen track the camera’s perspective in real time, and synthesize it with the real picture before the camera lens, thereby creating an infinite sense of space. For example, in the film and television industry, actors can build a shooting scene with an XR real-time rendering engine, output and synthesize through the server, map the spatial relationship between characters and scenes in real time, and use rendering technology to restore the dynamic digital scene in the camera on the LED screen. The performance can be performed in the virtual space constructed by the LED screen. Applying this 3D stereoscopic scene template and real lighting simulation technology to film production can create a real-like depth of field change for the audience, and it is difficult for the naked eye to distinguish defects.
Simplicity
Since the epidemic, travel has been subject to many restrictions, especially if the film advertising team has to travel to different regions to shoot, it is very troublesome and the cost is not small. XR virtual shooting can complete the shooting of different time and space scenes in a fixed time and space, regardless of location or season, which greatly reduces travel costs and greatly improves convenience.
Low Cost
Compared with the traditional green screen technology, the shooting technical team can interactively play the 3D environment created by it on the LED display screen. During the process, not only can the playback content be edited in real time, but also pixel-accurate tracking can be performed. Resolve the rendered 3D image for perspective correction. Secondly, the LED display stage technology and playback technology have greatly reduced the post-production time for the visual effects department, and the cost of video production has also been greatly reduced. Furthermore, the giant LED screen stage combined with XR technology presents more precise highlights, reflections and bounces on film reflective clothing. In this way, XR extended reality virtual shooting can allow the director to directly experience the real-time picture on the spot, shorten the workflow, greatly reduce the post-production workload, improve production efficiency, and create more magical scenes according to the director’s needs. The use of LED screens and virtual production technology in shooting has changed the traditional way of film production, bringing more possibilities and convenience to film shooting. The combination of virtual production technology can also greatly save production time and cost for video production.
XR virtual shooting requirements for LED display
Different from ordinary displays, LED displays used for virtual shooting must have the characteristics of high stability, good performance and good quality. So, what are the characteristics of the LED display used for xR virtual shooting?
High Contrast
Virtual shooting is an infinite requirement to be close to the real scene, and the higher contrast makes the picture appear more real.
High Brightness
Compared with the traditional green screen, the LED display background is prone to reflection, and the high brightness and high contrast make the reflection difficult to detect.
Super Vision
Different from the conventional large screen, the XR virtual scene needs to cooperate with the multi-angle camera to complete the multi-scene effect of the film or other film and television production, so this requires the LED display to have a wider field of view in practical applications.
Display Effect
In general, the light source devices used for XR photography are more demanding. Especially in film shooting, due to the high requirements of film level, in actual use, it is also necessary to ensure the corresponding display effect and create an immersive atmosphere.
High-end LED display helps XR virtual shooting
In order to meet the high requirements of XR virtual shooting for LED displays, the SRYLED team actively responded and invested a lot of technical resources to develop a new product RE PRO with excellent reliability and performance.
RE PRO adopts a professional stage rental cabinet design, using high-precision die-casting aluminum cabinets, which are assembled smoothly and without gaps, and the picture looks more realistic; the module adopts a magnetic suction design for front and rear maintenance, which is very convenient to disassemble and assemble, and can meet the high-efficiency requirements of the shooting site.
At the same time, in order to enable the product to better realize the XR display effect, high-color gamut lamp beads are customized to make the virtual display more realistic; for the requirements of high refresh rate, the hardware IC and the number of scans are specially designed for high refresh to achieve 3840hz to 7680hz ultra high refresh rate.
In addition, RE PRO adopts XR shooting special system, which can support HDR, 22bit+, fine grayscale, color management, low latency, 14-channel color calibration, color curve and other functions.
