CineMaster is a framework focused on high-quality, cinematic video generation. Through 3D awareness and precise controllability, it empowers users to control object placement, camera movements, and the arrangement of rendered frames with the precision of professional film directors. The framework operates in two stages: The first stage involves an interactive workflow that allows users to intuitively construct conditional signals in 3D space. The second stage leverages these signals as guidance for a text-to-video diffusion model, generating the user's desired video content. CineMaster's key advantages lie in its high degree of controllability and 3D awareness, enabling the generation of high-quality, dynamic video content suitable for film production, advertising creation, and related fields.
