TikTok and BytePlus have jointly launched the "Classic Hong Kong Film Restoration Project," which uses AI technology to restore old Hong Kong films, with the first application of the AIGC visual large model. During the restoration process, the BytePlus team addressed issues such as clarity, fluency, color, and flaws through their proprietary AI algorithms, bringing new life to these classic films and restoring Brigitte Lin's timeless beauty from 40 years ago. The restoration project is open for external enterprises to use, aiming to bring more 4K high-definition video works to the audience.
