Vidu Q3 Drama (Short Play)

[Core Function] Vidu Q3 Drama (Short Play) is a script-to-video model that turns a written script plus character, scene, and prop reference images into a complete multi-shot short drama, automatically planning the shots, transitions, and camera work in a single pass. [Strengths] It excels at multi-shot narrative coherence, automatic storyboarding and cinematography, and keeping the identity of referenced characters, scenes, and props consistent across every shot. [Best For] Highly recommended for: scripted short dramas and web-series episodes, narrative short-form ads and brand stories, rapid storyboard and pre-visualization, and character-driven reels built from a cast of reference assets. [Limitations] Do NOT use this model to simply animate a single image as-is (use a standard image-to-video model such as Vidu Q3 Pro instead); it requires a script and 1-14 reference assets, supports only 8-12 second clips at 1080p in 16:9 or 9:16, and is not intended for pixel-perfect single-product shots or complex multi-object physics. [Routing] Choose Vidu Q3 Drama when the user provides a script or narrative beats plus character/scene/prop references and wants an automatically directed multi-shot short play. If the user only wants to animate a single image or needs one continuous clip without scripted scene changes, route to a standard image-to-video model such as Vidu Q3 Pro.
