On September 23, 2023, China Film report, a CCTV-6 movie channel, made a major report on the construction of a hardware national production virtual studio by Changsha Film Group, hitting the shooting site of the long film test short film Oath. BOSMA Boguan is the forerunner of domestic 8K camera, its 8K full-frame camera B1 helps long film hardware to be shot in the national production virtual studio, stable quality and ultra-high definition immersive texture add a touch of domestic science and technology beauty to long film test short films such as "Oath" and "entering the Sea".

All the domestic-made studios are renovated and upgraded, opening the unlimited possibility of XR+8K

Changying, founded on October 1, 1945, whose full name is "Changchun Film Studio", is the first film studio in New China. After the baptism of the gunfire of the War of Liberation, it has a history of 74 years and is known as "the cradle of the new Chinese film industry". Among them, the third studio of Changying is the earliest and most well-preserved special effects studio in China, and it was once one of the places where classic films such as "daughter of the Party" and "Heroes and daughters" were shot.

With the rapid development of film and television science and technology, Changying is closely following the development of the times and vigorously implementing the national cultural digitization strategy, the third studio of Changying has introduced advanced technology on the basis of its original appearance, and set up a film-grade XR (extended reality) virtual studio through domestic hardware equipment such as LED curved screen and 8K camera. In the long film test short film "Oath" shooting, the domestic 8K camera forerunner-Boguan 8K's full-frame B1 equipped with domestic brand long walk ghost axe zoom group lens, the scene using domestic brands Nanguang EVOKE 900C, EVOKE 1200B and DYNO 650C and other lighting equipment to supplement the light source, to create a full line of domestic shooting settings.

Boguan 8K B1 competes with foreign brands, and immersive visual effects break the boundary between virtual and real.

In the field of content production, XR is specifically referred to as a workflow that includes a LED display, a camera tracking system and a powerful graphics engine. It is a virtual production method that places performers in a virtual world in real time without a green screen and post-production process. Benefiting from the full-frame advantage of B1 and its rich and comprehensive functional interface, during the short film shooting, the photographer fixed the positioning tracker on the front-end camera B1 handle and connected to the XR production domain through the network cable interface. At the same time, the 12G-SDI interface equipped with the B1 body was connected to the XR production domain to confirm the positioning according to the real-time output picture.

The image output of the real-time engine is synchronously combined with the tracking of the camera, and the immersive visual effect brought by the ultra-high definition image quality perfectly breaks the boundary between the virtual and real, and highly creates a real scene atmosphere. In the shooting site, the completion of a work is far more than one position, in the face of multi-position shooting, B1 Genlock and TC IN / OUT time code synchronization function will also play an important role.

It is worth mentioning that during the shooting of the long film test short film "Oath", Boguan 8K full-frame camera B1 was shot synchronously with foreign brand cameras, competing on the same stage, and each shot was shot once with two cameras, and finally mixed and cut in the later stage. Gong Zhaohui, the producer of the long-film test short film Oath, mentioned in the China Film report on the CCTV-6 film channel on September 23, "from the shooting effect, at present, there should be no big difference (with foreign equipment). We also want to do this test because we want to shoot imported equipment once, domestic equipment once, and finally we shoot this twice, and then mix and cut it. Let's take a look at it." The whole shooting effect of ours. "

The teacher team of Zhang Jupeng said, "this work includes domestic drone camera systems and foreign brand cameras, of which at least 1 hand 3 is shot by domestic equipment with long trail lenses. Compared with foreign brand camera lenses, the shooting effect is as good as that of foreign brand cameras. After the later stage, the scene tone consistency is very high, and the finished product effect is particularly satisfactory."

As a category with high technical content in film and television equipment, cameras have always attracted much attention, and the localization process of front-end collection touches people's hearts. At the same time, in the first half of 2023 alone, there were more than 31 films in the Chinese film market, of which domestic films accounted for nearly 80%. From the localization of film science and technology to the flourishing domestic film market, domestic development is merging into various fields. It is an indisputable fact that with the continuous development of China's science and technology, the level of local film production in China is constantly improving, Chinese film technology is becoming more and more mature, and cutting-edge video technologies such as XR and 4K / 8K ultra-high definition are also vigorously promoting the process of China's film industry. The BOSMA crown helps Changying Group hardware production virtual studio shooting. It is with practical actions that Chinese films move forward from a big film country to a film power. As a forerunner of domestic 8K camera, BOSMA Boguan integrates more than 20 years of optical technology and 10 years of intelligent electronic technology into the research of front-end ultra-high-definition camera technology, and has successfully built the M43, full-frame 8K camera product matrix, which is only the starting point, scientific and technological innovation has no limit and no end.
