Keyframe Prompt Formula Card: A Structured Visual Guide

Turn the keyframe + prompt approach for FLUX 3 Max image-to-video into a readable visual instruction manual. The piece uses two keyframes: the first is a dark card labeled with the four-part structure "Subject / Action / Camera / Light," and the second is a finished-style storyboard card with that same structure filled in; the model generates a continuous progression between the two, making the "formula → finished piece" transformation legible in one pass within 5 seconds. It works well in developer docs, model introduction pages, or internal team prompt guidelines as an example of keyframe orchestration for image-to-video: how to use one starting frame to define structure and one ending frame to define the landing point, and how to make the two frames connect naturally along the timeline. In the schema, duration, resolution, aspect_ratio, reasoning_level, and generate_audio all use conservative values suited to card-type content, making it easy to reproduce.
