Today’s film review： What are the black technologies of the Winter Olympics？ We decrypt it for you.

Special feature of 1905 film network On February 20, 2022, the Beijing Winter Olympics officially came to an end. During the event, a variety of winter Olympics technologies were unveiled, which surprised athletes and audiences and made filmmakers feast their eyes. Nowadays, China movies are undergoing technological innovation, and the digital industrialization of movies has become an important issue in the industry. So, will the fire of "Winter Olympics in Science and Technology" ignite the film industry and promote the development of China movies? In this programme, Wang Chunshui, director of the Virtual Production Laboratory of the Future Image High-tech Innovation Center of Beijing Film Academy, came to the studio to decipher the black technology of the Winter Olympics with us and analyze which technologies are expected to help the development of China’s film industry.

Many viewers said that the "movie-watching" experience of this Winter Olympics was excellent, and sometimes they could even feel the snowflakes and ice flowers coming at them. Such a good impression benefited from the all-round support of Winter Olympics Technology. Wang Chunshui said: "The whole winter Olympics of science and technology is divided into several major parts, one of which is called preparation, which is related to sports and how to prepare for the war; Part of it is related to the host city, which is called hosting the competition and how to host the competition; The other is what the audience and friends can feel personally, watching the game, which is a topic closely related to film and television. " Wang Meng, a gold medal commentator, once said that "my eyes are the ruler", which is not only the embodiment of her being an excellent short track speed skater, but also closely related to the ultra-high-definition broadcast technology of this Winter Olympics. This ruler is based on a good broadcast picture of the event.

Take the "watching games" part for analysis, which contains a lot of winter Olympics technology. This Winter Olympics is the first time in Olympic history that all games are broadcast in 4K, and the ultra-high-definition visual experience can not be separated from the technical support such as 5G and VR. Another technical highlight is "broadcasting on the cloud", which is a great technological innovation and solves the problem that many jobs can not be carried out on the spot due to the epidemic situation to some extent.

Free-view black technology upgrades the new experience of Winter Olympics, so that the audience can fully feel the "speed and passion" of Winter Olympics. This Winter Olympics can not only watch the game in a plane, but also experience the scene of the Winter Olympics through 360-degree VR glasses. Here, you can watch the details of Gu Ailing’s whole jumping process in the freestyle ski platform through VR technology, and you can personally feel the excitement and thrills of sledding across the track. VR technology has been loved by everyone in the last PyeongChang Winter Olympics, because it can make the audience feel immersive, and this winter Olympics introduced a very big innovative technology — — Free viewing angle, 360-degree VR viewing angle is fixed and variable; The free angle of view can be changed in both position and angle of view. It can be imagined that the audience can watch the game around the stadium. During the course of the event, you can switch the viewpoint by sliding the screen, so as to get more different look and feel experiences.

This free-view technology can easily remind the audience of the "bullet time" inside. Wang Chunshui said: "The Matrix was shot by a single person, and hundreds of cameras may be used. But now we only use dozens of cameras to capture certain angles, and calculate those angles that are not captured in the middle. This technology can also be applied to the calculation of face changing." These achievements in the field of real-life digitalization can also promote the progress of film and television visual technology if they are put into the film and television industry.

The concept of "going to the cloud" introduced by this Winter Olympics has also triggered a very heated discussion in the film circle. Wang Chunshui said: "It is a very important’ behind-the-scenes hero’." The visual feast enjoyed by the audience is inseparable from this "cloud" technology. Take the studio of "Today’s Film Review" as an analogy. Under the normal live broadcast, a pilot room is needed next to the studio to control the background and make programs. With the "cloud" technology, all the materials can be put online. Even if the broadcast team is far away from the studio, they can make programs remotely anywhere in the world without sending staff to the scene, which can greatly save labor costs and time costs. Cloud production has also been discussed for a long time in the film industry. Maybe one day, the crew can complete the film production without going to the scene, just like the Olympic Games.

Another technology is the arena simulation system (VSS system). The stadium simulation system of this Winter Olympics simulates the competition venues one by one, presenting the most authentic side of the Winter Olympics to the audience. The technical team simulates all the elements that can be involved in the arena, providing a very good visual feast for the global audience. The twelve competition venues of this Winter Olympics are all digital twins, and there are six non-competition venues, which show every wonderful corner of the Winter Olympics in an all-round way. First of all, the audience came to the flower skating arena, entered the Capital Gymnasium, and chose their favorite viewpoints in the one-to-one simulation arena. They could watch the perspectives of judges and commentators in the audience, VIP area and even. From the referee’s perspective, you can see the key movements of athletes. For the broadcast team, they can choose a convenient shooting angle in advance and present it to the audience. Walking to the outdoor stadium, the venue in the National Ski Jumping Center is built on the mountain, and this huge venue also collects data in advance. Through the virtual camera, you can choose to capture any angle and detail of the stadium.

The winter Olympics of science and technology began in the winter Olympics, not just in the winter Olympics. Several technologies shared today have a common feature, and they all belong to film and television. Only when they are applied in more fields and better serve the society can they exert their greatest commercial and social value. I believe that Winter Olympics technology will not only last for more than ten days, but also play a positive role in promoting the film and television industry in the future, and filmmakers will continue to tell the story of China in camera language!
