Social Short (Vertical) Video Prompt Prompt for Mochi

This is the Mochi version of the social short (vertical) video prompt prompt: a vertical, hook-first clip formatted for Shorts, Reels, and TikTok. It is formatted the way Mochi takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.

Reference image — keyframe

Attach a reference image: choose a file, drag & drop it here, or click here and paste. It never leaves your browser.

Attach reference image

Push copies this prompt with a reference line naming your image, and downloads the image file — attach it in the model to complete the pair. This page stages the pair for you; it cannot upload into the model itself (sites cannot reach into each other), so the final attach happens there. The image is downscaled to at most 1024px and stored only in this browser, paired with this prompt. If browser storage is full, it is kept for this visit only.

Using this prompt with Mochi

Mochi 1 (Genmo) is an open-weights (Apache-2.0) video model that takes long, highly descriptive, motion-focused prose: describe the movement itself in detail — speeds, directions, how bodies and fabrics move — because motion fidelity is its strength. It is text-to-video only: no image conditioning, so a keyframe cannot anchor it, and no audio. Output is 480p at about 84 frames per generation — treat it as a motion sketch and prototyping model, or an open pipeline component, rather than a finishing tool.

What this route costs — and how to pay less

Cost structure: open weights (Apache-2.0) — Mochi runs on your own hardware, so the marginal cost per generation is zero; Genmo also hosts a playground. The same prompt is pre-configured in this library for every major model, so you can run it on whichever route fits your budget — comparing the structures before you generate is a free way to save money.

Replace the bracketed placeholders — [SUBJECT], [THE VISUAL HOOK], [PAYOFF] — with your own details before pasting.
