Show HN: Genjutsu AI – Replace objects in existing videos (genjutsuai.net)

Genjutsu AI, developed by Higgsfield, has unveiled an innovative video-to-video model that allows users to replace objects and restyle scenes in existing videos while retaining original motion, camera movements, and timing. This tool enables creators to keep the same subject in a video but transform the surrounding environment, style, or specific objects. Users can upload a clip and specify the desired changes—whether to swap a modern coffee cup for a vintage vase or to restyle an entire scene from a sunny street to a rainy cyberpunk alley. This technology is particularly significant for the AI/ML community as it opens new avenues for filmmakers, editors, and content creators to produce engaging material without the need for extensive reshoots or complicated editing. The process is streamlined into five easy steps, allowing for a focus on creativity rather than technical hurdles. By offering various resolution options and a credit-based payment system, Genjutsu AI makes high-quality video editing more accessible, ultimately driving forward the evolution of digital storytelling and content creation.
