Beijing News (Reporter Teng Chao) From April 18th to 21st, during the 14th Beijing International Film Festival, the new 4k versions of "a plan " and " " were screened globally in the "Tribute·Repair" section. Premiere. The 4K version shown this time is supported by the "Classic Hong Kong Film Restoration Project" jointly launched by the China Film Archive, Douyin, and Volcano Engine.
The new 4k versions of "Plan A" and "The Pledge of Allegiance" had their world premiere in the "Tribute·Restoration" section.
"Plan A" and "The Pledge of Allegiance" were released in 1983 and 1978 respectively, more than 40 years ago. After the original filming negatives of the two films were scanned in 4k specifications in Hong Kong, they underwent digital restoration by the China Film Archive, AIGC visual large-scale technical restoration by the Volcano Engine, and artistic restoration by both parties, and finally achieved clarity and smoothness. Achieve 4K effects in terms of brightness, color, etc., bringing a different visual experience to movie fans. During the pre-screening event of
"Project A", senior film producer Sun Rong, who once served as the vice president of Jackie Chan China, shared with fans on the spot that Jackie Chan's "famous scene of jumping from the clock tower" contributed by Jackie Chan in "Plan A" was filmed for seven days. Jumped twice from a bell tower above 15 meters. The action scenes of this film combine elements of authenticity, acrobatics, and danger, establishing Jackie Chan's classic style of comedy action films in the future.
's carefully designed martial arts movements are smoother and smoother with the support of intelligent frame insertion technology. There was a fight scene in "Plan A". Dewey, who had fallen to the ground, faced Sammo Hung who was holding a big sword high, and kicked the knife away to turn the defeat into victory. This is actually not common sense. How did Dewey stand up and kick the big knife away in an instant? ? The Volcano Engine uses intelligent frame insertion technology to insert the middle value of the AI-predicted action between two martial arts actions, and this solves the mystery. Dewey put his hands on the ground and prepared to stand upside down. Then he exerted force on his waist and used his feet to twist Sammo Hung's hand. Sammo Hung lost his strength and the sword fell.
"The Pledge of Allegiance" is another masterpiece of the "Classic Hong Kong Film Restoration Project" that had its world premiere at the Beijing Film Festival. The film was the box-office champion of Hong Kong movies in 1978. Its director, Xu Guanwen, was the undisputed "King of Comedy" in the Hong Kong film industry before the rise of Stephen Chow.
The digitization and restoration of the film "The Pledge of Allegiance" will be completed in 2024. The original filming negatives were scanned in 4k format in Hong Kong using an arriscan scanner, and the sound restoration was derived from the preserved 35mm mixed sound of the film.
In the past, the film restoration process was trivial. It would take an experienced restorer one month to complete a film. In recent years, the rapid development of AI technologies such as deep learning has greatly improved the quality and efficiency of old film restoration.
As AIGC visual large model technology is widely used in more film and television scenes, Ma Kede, assistant professor of the Department of Computer Science at City University of Hong Kong, believes that this technological trend may become the mainstream of 4K film restoration in the future. Problems such as synchronization will be solved more effectively through aigc. In the future, it is even expected that AI will learn to automatically judge the repair effect. "
