Wan-AI's **Wan 2.7** — flagship video model with multi-reference conditioning and audio-driven lip-sync — hosted on the **RunComfy Model API**.

```bash
npx skills add agentspace-so/runcomfy-skills --skill wan-2-7 -g
```

## When to pick this model (vs siblings)

| You want | Use |
|---|---|
| Lip-sync video to an audio track you supply | **Wan 2.7** (`audio_url`) |
| Multi-reference fine motion control | **Wan 2.7** |
| Smooth transitions, accurate motion physics | **Wan 2.7** |
| Currently-#1 blind-vote video model | HappyHorse 1.0 |
| Multi-modal cinematic with image+video+audio refs + in-pass voice generation | Seedance 2.0 Pro |
| Cinematic motion editing on existing footage | Kling Video O1 |
| Ultra-fast iteration | LTX 2 |

If the user said "Wan" / "Wan 2.7" / "wan-ai" / "alibaba 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

### `wan-ai/wan-2-7/text-to-video`

| Field | Type | Required | Default | Notes |
|---|---|---|---|---|
| `prompt` | string | yes | — | Up to ~5000 chars / ~1500 tokens. |
| `audio_url` | string | no | — | WAV/MP3, 3–30s, ≤15MB. **Drives lip-sync.** Omit → background music auto-generated. |
| `aspect_ratio` | enum | no | `16:9` | `16:9`, `9:16`, `1:1`, `4:3`, `3:4`. |
| `resolution` | enum | no | `1080p` | `720p` or `1080p`. |
| `duration` | enum | no | `5` | 2–15 (whole seconds). |
| `negative_prompt` | string | no | — | Up to 500 chars. Concrete issues to avoid. |
| `enable_prompt_expansion` | bool | no | true | Auto-rewrites short prompts. Disable for literal control. |
| `seed` | int | no | — | 0..2^31-1. Reuse for variants. |

## How to invoke

**Default (5s 1080p 16:9, prompt-expanded):**

```bash
runcomfy run wan-ai/wan-2-7/text-to-video \
  --input '{"prompt": "<user prompt>"}' \
  --output-dir <absolute/path>
```

**Audio-driven lip-sync (your own track):**

```bash
runcomfy run wan-ai/wan-2-7/text-to-video \
  --input '{
    "prompt": "Medium close-up of the spokesperson, warm key light, locked tripod, slight breathing motion.",
    "audio_url": "https://.../voiceover.mp3",
    "duration": 12,
    "aspect_ratio": "9:16"
  }' \
  --output-dir <absolute/path>
```

**Literal control (no auto-expansion):**

```bash
runcomfy run wan-ai/wan-2-7/text-to-video \
  --input '{
    "prompt": "<exactly what you want, verbatim>",
    "enable_prompt_expansion": false,
    "negative_prompt": "no subtitles, no flicker, no distorted hands"
  }' \
  --output-dir <absolute/path>
```

## Prompting — what actually works

**Camera + motion in plain English.** "Slow dolly in", "locked tripod, low angle", "handheld follow", "crane move from above". Front-load the shot.

**One primary action per clip.** Don't pile up multiple competing actions.
