On October 20, at the 2021 China Science and Technology Film and Television Summit Forum (Chongqing), Dawa Future (Chongqing) Imaging Technology Co., Ltd. (hereinafter referred to as "Dawa Future Technology") released the first full-LED virtual film concept film "Unknown" in China. planet".
It is reported that Dawa Future Technology was established in 2018, mainly to carry out virtual reality, game development and film and television production industry scientific research, development, talent training and other whole industry chain business.
Lu Qi, CEO of Dawa Future Technology, said that previously, the most advanced virtual production technology in China is that actors perform in front of the green screen, and digital content production companies create virtual images behind the scenes, and then synthesize the two. This synthesis process requires a lot of human labor. Because the actors performed in front of the green screen relying on brain-filled pictures, the final synthesis effect often failed to meet the director's expectations, so they were forced to rework, resulting in a very long production cycle and very high costs.
With full LED virtual shooting, the actors perform in the virtual screen, and the difficulty of performance is greatly reduced. In addition, the synthesized film can be output in real time, and the effect of the finished film can be seen directly, which is easy to modify in time. In addition, there is no need to spend a lot of manpower for matting, the shooting cycle is greatly shortened, and the shooting cost is greatly reduced.
According to reports, the all-LED virtual shooting is based on the original virtual production and virtual shooting technology of Dawa Future Technology, adding a number of independent research and development technologies such as real-time algorithms, real-time compensation, and the linkage and fusion of virtual cameras and real cameras. While the real camera shoots the actor's performance, the virtual camera adjusts the virtual image in real time by capturing the real camera lens, so that the real-time output video can realize the seamless synthesis of the real and virtual images.
In addition, when a real camera is shooting a live-action performance, it may only be able to arrange part of the LED screen, and part of it will be a black screen. This system realizes picture compensation through real-time algorithm and real-time compensation, so that the real-time output video cannot see the black screen.
