  Define the scene’s style, mood, and key elements. Example:  
  “A serene forest landscape at dawn, mist hovering over the trees, a deer slowly wandering, softened by early light.”  
- **Leverage Frames-to-Video**  
  Upload 3–5 reference frames to guide motion direction and composition.  
- **Iterate for Detail**  
  For more intricate visuals, break your concept into multiple prompts and stitch segments post-generation.
