## When to pick this model (vs siblings)

| You want | Use | |---|---| | Multi-shot story with character / wardrobe consistency | **HappyHorse 1.0** | | Native audio in the same generation pass | **HappyHorse 1.0** | | Currently-#1 blind-vote video model | **HappyHorse 1.0** | | Detailed lip-synced dialogue + reference video | Seedance 2.0 Pro | | Fine motion control + multi-reference conditioning | Wan 2.7 | | Ultra-fast iteration (sub-second per frame) | LTX 2 | | Cinematic motion editing on existing footage | Kling Video O1 |

If the user said "HappyHorse" / "happy horse video" explicitly, route here regardless.

## Prerequisites

1. **RunComfy CLI** — `npm i -g @runcomfy/cli` 2. **RunComfy account** — `runcomfy login` opens a browser device-code flow. 3. **CI / containers** — set `RUNCOMFY_TOKEN=<token>` instead of `runcomfy login`.

## Endpoints + input schema

### `happyhorse/happyhorse-1-0/text-to-video`

| Field | Type | Required | Default | Notes | |---|---|---|---|---| | `prompt` | string | yes | — | Up to 2,500 chars. 6 languages (CN/EN/JP/KR/DE/FR). | | `aspect_ratio` | enum | no | `16:9` | `16:9`, `9:16`, `1:1`, `4:3`, `3:4` only. | | `resolution` | enum | no | `1080P` | `720P` or `1080P`. | | `duration` | int | no | 5 | 3–15 seconds. | | `seed` | int | no | 0 | 0..2^31-1. Reuse for variant comparisons. | | `watermark` | bool | no | true | Provider watermark. |

## How to invoke

**Default (16:9 1080p 5s):**

```bash runcomfy run happyhorse/happyhorse-1-0/text-to-video \ --input '{"prompt": "<user prompt>"}' \ --output-dir <absolute/path> ```

**Vertical short (9:16, 8s, no watermark):**

```bash runcomfy run happyhorse/happyhorse-1-0/text-to-video \ --input '{ "prompt": "<user prompt>", "aspect_ratio": "9:16", "duration": 8, "watermark": false }' \ --output-dir <absolute/path> ```

**Cheaper test pass (720p):**

```bash runcomfy run happyhorse/happyhorse-1-0/text-to-video \ --input '{"prompt": "<user prompt>", "resolution": "720P", "duration": 3}' \ --output-dir <absolute/path> ```

The CLI submits, polls every 2s until terminal, then downloads any `*.runcomfy.net` / `*.runcomfy.com` URL from the result into `--output-dir`. Stdout is the result JSON. Stderr is progress.

## Prompting — what actually works

**Describe motion over time, not a still.** "A woman turns from the window, walks two paces to the desk, picks up the cup, lifts it to her face, takes a sip" beats "a woman drinking coffee".

**Camera + shot in plain English.** Front-load the shot: `"Wide shot. ..."` / `"Tracking shot. ..."` / `"Locked tripod, low angle. ..."` works as a real directive. Specify lens feel: `"35mm anamorphic"`, `"shallow DOF"`, `"crushed shadows"`.

**One visual beat per clip when iterating.** Don't pile up "she walks AND the dog runs AND a car passes". Pick the beat, get it sharp, then layer with multi-shot prompts.

**Multi-shot consistency** — when describing two beats, restate the anchor at each: `"Shot 1: tall woman in red wool coat, blue scarf, in a rainy alley. Shot 2: same woman in red coat / blue scarf, now ducking under an awning."` HappyHorse holds the look but needs the anchor.

**Audio direction** — say what you want to hear: `"distant temple bells, footsteps on wet pavement, no dialogue"` or `"warm friendly tone, English"`.

**Anti-patterns:** - Static-frame descriptions (no temporal verbs) → motion will be vague. - Conflicting style directions → cancels. - > 2500 char prompts → degrades. - Aspect ratios outside the 5 supported → 422.

## Where it shines

| Use case | Why HappyHorse 1.0 | |---|---| | **Multi-shot brand stories with one consistent character** | Native cross-shot identity preservation | | **Talking-head explainers needing in-clip voiceover + ambient** | Synchronized audio in the same pass | | **Multilingual short-form ads** | 6 prompt languages, no script-quality drop | | **Cinematic 1080p delivery** | Native 1080p output, broadcast-ready | | **Blind-vote leader for general video quality** | #1 on Artificial Analysis Video Arena |
