Topview 3D Builder Brings Previs to AI Video

Topview targets AI video’s biggest production weakness: spatial intent remains probabilistic. Separating deterministic staging from generative appearance is a genuinely useful workflow, though the previs scene cannot guarantee that downstream models preserve every creative decision.

• –Agent-native controls let users build and revise scenes through natural language in Codex, Claude Code, Cursor, and similar tools.
• –Local projects, Apache-2.0 code, and no required account make experimentation accessible and privacy-friendly.
• –Camera and layout previews can reduce wasted video generations, especially for ads, storyboards, and multi-shot continuity.
• –The current asset library is limited, with simple props, four built-in characters, and static poses rather than a full animation suite.
• –The workflow is strongest as a planning layer; final texture, lighting, motion, and character fidelity still depend on the downstream video model.
