SmartDirector: Keyframe-Conditioned Cinematic Video Generation with Narrative Pacing Control

ArXi:2605.27891v1 Announce Type: cross The narrative quality of a video fundamentally determines its perceptual value. Although existing video generation methods can produce visually appealing content, they predominantly rely on sparse conditioning signals such as text prompts or first/last frames, which limits precise control over narrative structure and temporal pacing. In this paper, we propose SmartDirector, a framework that enhances the narrative capacity of video generation models through multiple keyframes.
