Nowadays, "premium face" is highly regarded in the entertainment circle, and the fashion circle is also pursuing the "premium sense", and "premium" has gradually become the most prominent label of quality. In the field of film, from scripts, directors, actors, to editing and post-production special effects, every link is meticulously crafted in details, and strives to create fine films. Similarly, in order to better transform the digital signal composed of 0 and 1 into the light and shadow image in the eyes of the audience, the CINITY cinema system, a film projection system of China Film Group, has also repeatedly considered the details of light and shadow, using high dynamic range technology to present it. Richer levels of light and dark and picture details, by significantly improving the realism and fineness of viewing, make the high-level sense of the movie more prominent on the big screen.
On December 6, the space science fiction adventure blockbuster "Interstellar Exploration" produced and starred by Brad Pitt will be released in the mainland. At that time, audiences can go to the CINITY theater to experience the more high dynamic range. Delicate pictures and richer details, truly experience this high-level Hollywood blockbuster.
The lunar version of "Fast and Passion" interprets the high-level sense of the movie with a layered ultimate picture
In the film, Roy, a talented aerospace engineer played by Pete, is sent to space to investigate the cause of the out-of-control anti-matter response and the Earth’s survival crisis. It is known that the father of the astronaut who has been missing for 16 years may be the mastermind of all this. He traveled through the four planets of the Earth, the Moon, Mars, and Neptune, and embarked on an interstellar journey across the solar system, not only to save mankind, but also to save a father-son relationship that spanned time and space and his helpless self. The film has been released overseas, and was shortlisted in the main competition unit of the Venice International Film Festival, and achieved an excellent score of 84% freshness of rotten tomatoes and an average score of 80 for MetaCritic. The Wall Street Journal even predicted that Brad Pitt is expected to rely on the film. Superb performance nominated for Oscar.
For cosmic and space-themed movies like "Interstellar Exploration", the visual effects are crucial. Whether it is the vast galaxy, the deep universe or the blue Neptune, the shocking visual impact will become the deepest memory point of the audience. The lunar drag scenes and chasing gun battles in the film are particularly thrilling and adrenaline soaring, which can be called the lunar version of "speed and passion". However, the moon seen up close often loses the romance in the words of literati and writers and becomes lifeless. In such a gloomy lunar wasteland, it is not easy to create the tension and realism of a blockbuster action. Director James Gray specially invited NASA aerospace engineers as consultants to confirm the rationality of shooting on the moon, which provides theoretical support in terms of plot; CINITY cinema system provides technical support on the projection side, and the high dynamic range makes the moon uneven The surface looks richer in light and dark, showing a more delicate and full picture effect. The
film also boldly evaded the anti-physical phenomenon of "vacuum explosion sound" in previous space films, and almost all explosions are silent. With limited auditory assistance, the audience sitting in the CINITY theater mainly relies on the sense of sight. When watching many silent scenes, they can still enter the show in one second, and they can't help but sigh that CINITY is "true fragrance".
High dynamic range of the past and present
The dynamic range of a digital image refers to the ratio of the maximum and minimum brightness in a digital image, expressed by the logarithmic value log10 (Lmax/Lmin). The dynamic range of brightness that the human eye can observe is very wide, reaching 9.0 when pupil scaling is allowed, and it can reach between 3.0 and 4.2 regardless of pupil scaling. The dynamic range of mainstream image processing and display equipment is very limited, far lower than the observation ability of the human eye, which is called low dynamic range (LDR) image or standard dynamic range image (SDR).
The current film production standard defined by CINITY is 36fL in 2D. In 3D mode, the minimum single-eye peak brightness is 20fL, the maximum 28fL and the dynamic range of more than 6000:1, which is 3 times the traditional theater standard, which can not only alleviate the brightness of the traditional theater. The fatigue caused by the deficiency can show more details of the bright and dark parts of the picture, making the film look more delicate and richer.
In addition, CINITY Cinema adopts the self-developed CINITYLog EOTF curve, and uses 16bit quantization accuracy during the film production process, which overcomes the defects of traditional EOTF curve support for high brightness and high dynamic range, and has higher brightness for the futureStandard adaptability can also present the picture with the highest precision under the existing brightness conditions.
CINITY HDR uses real texture to create the high-level sense of movies. The dynamic range of digital images is an important indicator of image quality. In the HDR screen of CINITY, the brightness of the scene is recorded closer to reality, which can show the difference between "diffuse white" and "specular white", such as white paper in the sun, water surface, metal, etc., can be displayed in HDR It presents a texture that is closer to the real, thus creating a high-level sense of movie screen.
In fact, the application of CINITY high dynamic range technology brings the realism of the film to a new level, the black and white transition is more delicate, and the light and dark are more distinct. Huaxia Film aims to provide viewers with a better viewing experience. The high dynamic range technology of the CINITY projection system will further optimize the film texture, provide more film details, and comprehensively improve the film picture quality.
Currently, there are more than 30 CINITY cinemas in China. In the future, the CINITY cinema system will also be stationed in Western countries such as Europe and the United States and countries and regions along the “Belt and Road” to bring new viewing enjoyment to audiences in more regions.
