HappyHorse 1.1 prompting tips

Concrete visual and temporal direction helps the model create coherent motion.

  • Describe the subject, action, environment, shot type and camera movement in chronological order.
  • Use [Image 1], [Image 2] and matching details to explain what each uploaded image controls.
  • Choose the final aspect ratio before composing the shot and use 1080p for detail-focused delivery.
  • Separate details that must stay consistent from the movement or transformation you want to create.
