During inference, every user prompt is transformed into a six-slot schema for generating high-fidelity prompts for Anna Fantasy's video diffusion backbone.
The six slots include Shot, Lighting, Subject + Action, Background, Camera Move, Style, and Mood, with a total length of 25–35 tokens and the flexibility to omit unnecessary slots.
To address issues like blurry faces, choppy motion, over-exposed skin, and unexpected elements, specific instructions are provided such as adjusting camera angles, altering lighting, and redefining scene elements.
The prompt writing process emphasizes visual intent, directing users to consider camera placement, lighting conditions, and framing ownership to guide Anna's handling of the scene during diffusion-time alchemy.
