HappyHorse 1.1 Prompt Formula Card: A Visual Guide to Structured Writing
A 9:16 vertical short video that explains the prompt formula for happyhorse-1.1/text-to-video: camera language + subject and action + environment and lighting + style and texture + rhythm and duration. The five modules unfold layer by layer as cards, and the final segment converges into one composite example that can be reused directly. This work is pure text-to-video and does not rely on any reference images or first-frame material. All visuals and information hierarchy are driven by a single prompt, so it also demonstrates how the model performs on prompt adherence and inter-frame temporal consistency: the order in which cards enter, hold, and exit must be continuous, and the movement of text blocks must align with the narration rhythm. Use cases: previewing results before model integration, writing examples in developer documentation, and visual explanations when teams standardize prompt conventions internally. The 9:16 aspect ratio makes it easy to embed in mobile documentation or social channels.

Prompt
Vertical 9:16 explainer video, 10 seconds. Clean dark navy background with a subtle paper-grain texture. Five translucent glass cards slide in one by one from the lower third of the frame, each easing into a stacked card column with a soft spring motion: the first card shows a camera icon and a short camera-movement line, the second card is a human silhouette in motion, the third card is a light-direction arrow above a horizon, the fourth card is three sets of color swatches, and the fifth card is a clock face. As each card settles, a thin white label line beneath it sets it off. After the fifth card locks in, all five cards compress into a glowing horizontal formula bar that flickers briefly, then the formula bar expands into a long line of prompt text that types out character by character from left to right. A slow, deliberate camera push-in throughout, shallow depth of field, cool key light from the upper left with warm rim-light accents, crisp sharp typography, an uncluttered frame, no lens flare, and smooth, temporally consistent motion.
