The author illustrates the importance of using white models to control spatial structure in AI video generation, contrasting the film 'Bull Comes' with AI outputs. The article details the workflow of using updream's Previsualization Studio: generating coarse-grained 3D white models from a single reference image, adjusting character positions, and designing camera trajectories. By importing recorded white models into Seedance2.5, users can precisely control spatial relationships and camera movements, resolving misalignment issues common with text-only prompts. The article summarizes ideal use cases for white models, including large-scale establishing shots, complex crowd scenes, and brand commercials, emphasizing that this method is more stable and cost-effective than relying solely on text descriptions.
