Singapore-based AI startup Video Rebirth has officially launched BACH, a new artificial intelligence-powered video generation platform designed to create cinematic multi-shot videos with high levels of realism and consistency. The launch marks a major step for the company as competition intensifies in the rapidly expanding AI video generation industry dominated by firms developing next-generation creative tools for filmmakers, marketers, and content creators.
According to the company, BACH is capable of generating videos up to 30 seconds long while maintaining character consistency, emotional continuity, camera movement accuracy, and cinematic storytelling across multiple scenes. Video Rebirth stated that the platform was built to address one of the biggest limitations in current AI video tools, where generated clips often lose realism and continuity between shots. The company claims BACH is specifically engineered for professional-grade production workflows rather than casual consumer use.
The startup was founded by Dr. Wei Liu, a former distinguished scientist at Tencent and a leading figure behind Tencent’s Hunyuan AI model development efforts. Since its launch, Video Rebirth has attracted significant investor interest and recently secured US$80 million in funding from investors including AMD Ventures and several Asian strategic backers. The funding is expected to support commercialization of the BACH product line and global market expansion.
Before its public debut, BACH 1.0 Preview was independently evaluated on the Artificial Analysis Video Arena benchmark, where it reportedly ranked among the top AI video models globally. Video Rebirth says its proprietary “Physics Native Attention” architecture allows the system to better understand motion, lighting, object interaction, and cinematic direction. The company believes this approach can help produce videos with improved physical realism and creative control compared to many existing AI video tools.
Industry experts view the launch as another sign of intensifying competition in the AI-generated video market, where companies are racing to develop advanced “world models” capable of creating realistic and controllable visual content. Video Rebirth now joins a growing list of firms competing against platforms such as OpenAI’s Sora, ByteDance’s Seedance, and Higgsfield AI. Analysts believe AI-generated video could become one of the most commercially valuable segments of generative AI as demand rises across advertising, entertainment, e-commerce, and digital media production.
