How to prompt Runway Gen-4.5
Runway flagship generation model with professional/HDR output options.
Prompt strategy: Use direct production language: subject, environment, action, camera, lighting, timing and final state. Keep motion coherent and controllable. Avoid vague style-only prompting; describe what visibly changes over the shot and preserve reference identity when applicable.
