The director group of CCTV revealed the story behind the new technology program. < / P > < p > the pictures in this article are from the screenshot of micro record of Spring Festival Gala. < / P > < p > < strong style = "box sizing: inherit; font style: inherit;" > the "cloud" technology of the Spring Festival Gala on the main stage realizes the national reunion < / strong > < / P > < p > the creative performance "Niu Qi" adopts the way of remote "cloud" production. Wang Yibo and Guan Xiaotong, who are on the stage of the Spring Festival Gala, and < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%88%98%E5%BE%B7%E5%8D%8E "> Andy Lau < / a >, a successful combination of" cattle and men ". According to Zou Wei, deputy director of the Spring Festival Gala, the relevant passages of Andy Lau in "bull up" only account for one and a half minutes, "but Andy Lau has been shooting for more than 20 hours in a row, and he has to simulate and interact with various elements around him. In order to clap high five with the mechanical cow, he clapped more than 20 times. < / P > < p > Andy Lau and mechanical niubangzhang < / P > < p > this year's CCTV Spring Festival Gala welcomed special international friends through "cloud" communication. Andre Bocelli, a famous Italian tenor, joined the Spring Festival Gala with his son "cloud". Bocelli and his son wish the friendship between the Chinese and Italian people will last forever. While the two are singing, 154 Ultra HD screens on the "dome" of the Spring Festival gala show the faces of the "cloud" audience, wishing to cross the ocean. < / P > < p > this year's Spring Festival Gala stage has also set up a huge ring-shaped new media background wall, with 154 Ultra HD large screens distributed above the back area of the audience, which looks like a brilliant "dome". Each HD large screen has its own channel, which can not only present 154 different pictures, but also provide conditions for the "cloud" audience to participate in the interaction. The most beautiful night scenes of the song "China in the lights", the return cultural relics in the special program "national treasure home", the various skills of martial arts school children in martial arts "heroes of heaven and earth", and the gesture dance of children's song and dance "listen to me" Because of this "dome", more "cloud" audiences join in. Chen Linchun, chief director of the Spring Festival Gala, said that the "dome" has turned the audience into a performance area. "It has brought breakthroughs to the presentation of dance beauty and the richness of the program of the whole evening party." < / P > < p > the impressive dome at this year's Spring Festival Gala. < / P > < p > < strong style = "box sizing: inherit; font style: inherit;" > director group's "revealing secrets" new technology program; "> Zou Wei, deputy director of the Spring Festival Gala < / strong >: Niu Qi is positioned as a science and technology folk show, which is centered on the zodiac culture. In fact, the annual Spring Festival Gala folk program is essential, on the one hand, reflects the excellent traditional culture of China, on the other hand, it is also jubilant and enthusiastic. This year, we want to use the sense of technology and artificial intelligence to reflect our folk customs. < / P > < p > on the stage, you can see mechanical cattle and quadruped cattle (small mechanical cattle), which have the characteristics of the times in the folk atmosphere. Some of our cattle are packaged from traditional New Year pictures, and some are packaged from cattle heads in Yuanmingyuan. In short, we all extract traditional cultural symbols to package these artificial intelligence elements. In addition, we invited Liu Dehua, Wang Yibo and Guan Xiaotong, who are all cattle_ blank" href=" https://news.163.com/news/search?keyword=%E6%BC%94%E5%91%98 "> actors < / a > participate in the performance. 2020 is not easy for all of us, but we Chinese people are very amazing, so I think in this year's Spring Festival Gala, we can use the keyword "cattle" to boost our morale. In fact, Liu Dehua, Wang Yibo and Guan Xiaotong sing together through cloud technology. < / P > < p > < strong style = "box sizing: inherit; font style: inherit;" > creative program director Hao Jing < / strong >: 2021 is the year of the ox. we specially selected Andy Lau, Wang Yibo and Guan Xiaotong, the three actors of the Chinese zodiac, to create a "combination of ox and man". Those robot calves in the program are called quadruped cattle (quadruped robots), and there are two mechanical cattle more than two meters. We also brought in some elements of cattle, such as the year of the ox stamp 2021 issued by the general post office in the dome. < / P > < p > there are two points I want to emphasize: first, I think the shooting method is very interesting. This is the first time that we use XR to shoot singers remotely. We use a remote monitoring system, which can monitor the whole process of Andy Lau's video in real time in the computer room of the main station. We can see every slot and talk to him at any time. It's very like we are in the pilot room, and he is on the scene in hall 1 of the main station. < / P > < p > studios in different spaces are connected by new technologies. < / P > < p > Second, the XR team that did Andy Lau's show is the tan Yang team of CCTV, and AR technology is the Feng Yi team of CCTV. "Bull up" Beijing scene is AR technology, Andy Lau scene is XR technology. AR technology has two functions. The first function is to expand the space of large screen with virtual. For example, our opening large screen is a quadrangle courtyard, and AR is a courtyard of quadrangle courtyard, which combines AR and large screen. The second function is to connect Andy Lau's space and on-site space. Andy Lau's transition from virtual to reality uses ar. In addition to AR and XR, Niu Qi also has a third technology called real-time rendering system. Real time rendering technology is the technology that takes Andy Lau's matting to the scene, or transplants it to the scene remotely. Finally, Andy Lau "parachutes" to the scene of the Spring Festival Gala to perform on the same stage with Guan Xiaotong and Wang Yibo. < / P > < p > in Andy Lau's performance, the most difficult thing is to interact with virtual cattle. < p > < p > < strong style = "box sizing: inherit; font style: inherit;" > 2_ blank" href=" https://news.163.com/news/search?keyword=%E6%9D%8E%E5%AE%87%E6%98%A5 "> Li Yuchun < / a > cross dressing < / strong > < / P > < p > < strong style =" box sizing: inherit; font style: inherit; "> Zou Wei: < / strong > the whole program uses a film oriented production method, and we use the camera Milo motion contr, which is often used in film advertisingol。 In addition, we want the model to be able to complete the walk show in the desert, forest, lake and wheat fields to create an immersive look. We use such effects as green screen matting and post effect synthesis to integrate the model into the whole scene. < / P > < p > Milo motion control, a camera commonly used in movie advertising.

Hao Jing: < / strong > this program uses two technologies. The first one is to use the special effects technology of the film to shoot (using the technique of split lens shooting), and the second one is Milo motion Control device, the biggest feature of this device is that it can realize cloning and cross dressing. For example, when Li Yuchun appeared, one Li Yuchun became eight Li Yuchun in different clothes. < / P > < p > Li Yuchun realized "eight Li Yuchun" cross dressing in the program. < / P > < p > the highlight of the program is that Li Yuchun uses the mirror as a medium of crossing. What we pursue is an immersive experience, leading the audience into the desert, lake, forest, wheat field, and finally to the temple of heaven. Now many museums are actually creating this kind of immersive viewing experience, so that you can change the scene and experience it personally. The most difficult part of landscape nishang is the cloning technology and the creation of virtual scenes. These scenes are all created by the film special effects team with three-dimensional modeling. They are shot separately, and then the performers are implanted into these scenes. It takes about a month to make them. < / P > < p > other supermodels, Beifu students and other actors also need to practice how to integrate into the immersive scene over and over again. < / P > < p > < strong style = "box sizing: inherit; font style: inherit;" > Beijing News: < / strong > did these two programs encounter any difficulties when adding new technologies? < / P > < p > < strong style = "box sizing: inherit; font style: inherit;" > Zou Wei: < / strong > Milo motion control, a new technology, took about four hours to shoot Li Yuchun's paragraph in more than 20 seconds. Actors are also very hard, whether it's supermodel, Li Yuchun or Beifu students, in order to this more than 20 seconds of screen, constantly cooperate with the director group. < / P > < p > the scene of Andy Lau in bull up is remote recording, and we have done a strict split in the early stage. Andy Lau is in Hong Kong, China. We mainly use the technology of augmented reality and rely on the means of green screen matting to make Andy Lau in the whole scene. Unlike the previous green screen matting, Andy Lau interacts with the elements around him. We digitized the mechanical cow in hall 1 of the main station, made a three-dimensional model, and then implanted it into Andy Lau's space. When Andy Lau performs, he has to simulate the interaction between elements, which is a very difficult place. In the whole quarter and a half minutes of the song, Andy Lau only accounted for less than one and a half minutes, but for this one and a half minutes, Andy Lau shot for more than 20 hours in a row. < / P > < p > Beijing News reporter Liu Wei < / P > < p > editor Tian jianni proofread Lu Xi < / P > < p >
