Prompt Formula Card: A Visual Guide to Structured Video Prompt Writing
Use a short video to make happyhorse-1.0's structured prompt writing concrete: the image is a formula card floating above a dark desktop, with the card laid out in six sections—"subject + action + scene + camera + lighting + audio"—the labels lighting up section by section, and finally the whole card collapsing into a single copyable line of prompt. This piece is aimed at developers and content teams who need to quickly get started with text-to-video. Uses include internal writing-standard presentations, the animated-image slot on a prompt template documentation page, and demo clips of the model's capabilities. Because happyhorse-1.0 jointly produces video and native audio in the same generation, the faint keyboard sounds and ambient background noise when the card lights up are also written into the prompt, to show that audio descriptions can likewise go into structured fields. On the parameter side, only the fields already declared by the author's pipeline are used: 6-second duration, 1080p, 16:9, fixed seed for reproducibility. The whole piece is a single-shot close-up, relying on no external reference images and driven solely by the text prompt.

Model HappyHorse 1.0
Prompt
A single continuous close-up shot, looking slightly down at a dark graphite-colored desktop. A matte card floats above the desktop, bearing six neatly typeset labels arranged horizontally. A soft point of light travels down the card, illuminating each label in turn from top to bottom; each illuminated label briefly emits a faint amber glow and reveals a thin underline. Tiny dust particles drift in the beam of light. The camera pushes in slowly with a subtle parallax effect, keeping the card centered and fully legible, with a shallow depth of field at the edges of the desktop. Cool gray ambient light paired with a warm key light, restrained contrast, no lens flare. At the end, all the labels collapse into a single line of text at the center of the card. Calm, instructional pacing, no cuts, no people in frame.
