The film will be released nationwide on August 3.
The movie tells the story of Rong Jinzhen, who is gifted in mathematics but lonely and fragile, and devotes all her life to the cause of code-breaking. In the newly released "Interpretation of Dreams" visual effects special by
, screenwriter and director Chen Sicheng, and visual effects directors Wei Ming and Li Shuai interpret famous dream scenes such as the amusement park, digital vortex, Enniak, and Reed Lighthouse, and discuss them with each other. Behind the scenes of special effects production. For Rong Jinzhen, every dream means the blooming of thinking and a reflection of her subconscious mind.
Regarding the amusement park dream, the creative team made many drafts on the setting, and finally decided to simplify the complex. In the view of director Chen Sicheng: "Dreams do not need to be rich, they may only need to be concentrated in a particularly concrete state. ".
The facilities in the amusement park are given specific meanings, and many oriental aesthetic details are attached, such as the shadow puppets on the central pillar of the carousel.
Chen Sicheng revealed in the visual effects special that the pirate ship was the projection in Rong Jinzhen's dream of the pen given by Xiao Lili when she was leaving, the carousel came from the teapot and teacup used by the Rong family to drink water, and the huge chess came from He Xiyi Si's experience of playing chess, these are the best parts of Rong Jinzhen's subconscious. The purple density represented by the Ferris wheel crushes and destroys everything, which means that while Rong Jinzhen found inspiration for deciphering, she also said goodbye to the past.
Although the dream scene was subtracted, the amount of visual effects production for this dream was very large. Visual effects director Li Shuai said that there are many details on the Ferris wheel, and tens of thousands of CG lights are arranged on it for rendering, plus the collapse For dynamic cloth calculation, the rendering time for just one frame was as long as 62 hours. The entire scene required 1,500 rendering nodes and took 362 hours to render.
In addition, the shot of Rong Jinzhen falling into the whirlpool and then transitioning to the Rong family’s old house was also a difficult point in the visual effects production, as it required processing of special effects characters, cloth calculations, hair calculations, flowing bubbles, water textures, etc. Complex visual effects details, a single shot of 24 seconds, and a production cycle of nearly two months.
These visual effects shots in dreams not only need to bring a strong visual impact, but more importantly, reveal the inner world of the characters. As the visual effects director Wei Ming said: "Everything is perceptual and needs to be grasped accurately. The struggle is how to integrate emotions into this picture. "
It is reported that all the visual effects work for the movie "Decryption" was completed by morevfx, the top domestic visual effects team, with founder Wei Ming and visual effects director Li Shuai serving as the film's visual effects director. The visual effects work of the film is not just post-production of visual effects, but also requires the visual effects team to follow the entire filming process. As can be seen in the
visual effects special, the visual effects team almost ran through the entire creative cycle from dream deduction at the script stage, to dynamic preview during shooting, to post-production visual effects production, demonstrating the rigorous and professional Chinese film industrialization process. During the preparation of
, the visual effects team divided Rong Jinzhen's ten dreams into different stages. According to Rong Jinzhen's mental state at different stages, the dreams also corresponded to realistic, surreal and abstract visual effects styles. During the shooting, the visual effects team made dynamic previews of complex visual effects shots, and worked with the photography team to dismantle the shooting plan, allowing the actors, photography, art, visual effects and other principals to establish clear shooting goals and division of labor to improve shooting efficiency.Since dream scenes, dream and reality transitions are all a combination of real shooting and special effects, they need to be shot in layers. On-site pre-synthesis is also an essential link, so that problems can be discovered and adjusted in time.
In addition, the visual effects team will also do a lot of material and data collection work on site to prepare for post-production. For example, in the dream of the Reed Lighthouse, the reeds and the base of the lighthouse were shot in real scenes, while the tower body and top of the lighthouse were built in a shed. The visual effects team needed to take aerial shots of the surrounding environment of the real reed scene, and record the height and height of the camera. The data of the elevation angle is then combined with the real scenes and studio shots.
As visual effects director Li Shuai said: "As a form of artistic expression, movies bring people to a different world through stories, images, sounds and visual effects, just like in a dream, giving people A kind of empathy and resonance."
