  Animate any still image on RunComfy — this skill is a smart router
  that matches the user's intent to the right i2v model in the
  RunComfy catalog. Picks HappyHorse 1.0 I2V (Arena #1, native audio,
  identity preservation) for general animations, Wan 2.7 with
  `audio_url` for custom-voiceover lip-sync, or Seedance 2.0 Pro for
  multi-modal animation from image + reference video + reference
  audio. Bundles each model's documented prompting patterns so the
  caller gets sharper output without burning iterations on the wrong
  model. Calls `runcomfy run <vendor>/<model>/image-to-video` (or
  endpoint variant) through the local RunComfy CLI. Triggers on
  "image to video", "image-to-video", "i2v", "animate image", "make
  this move", or any explicit ask to turn a still into video.

**Image-to-video, intent-routed.** This skill doesn't lock you to one model — it picks the right i2v model in the RunComfy catalog based on what the user actually wants: portrait animation, custom-voiceover lip-sync, or multi-modal composition.

```bash
npx skills add agentspace-so/runcomfy-skills --skill image-to-video -g
```

## Pick the right model for the user's intent

| User intent | Model | Why |
|---|---|---|
| Animate a portrait — keep identity stable | **HappyHorse 1.0 I2V** | #1 on Artificial Analysis Arena (Elo 1392); strong facial fidelity |
| Product reveal / 360 / macro motion | **HappyHorse 1.0 I2V** | Geometry preservation + smooth camera moves |
| Native synchronized ambient audio in one pass | **HappyHorse 1.0 I2V** | In-pass audio synthesis |
| Animate **and** lip-sync to a **custom voiceover track** | **Wan 2.7 + `audio_url`** | Accepts your own MP3/WAV (3–30s, ≤15MB) and drives lip-sync to it |
| Multi-language dub variants (same image, different audio per call) | **Wan 2.7 + `audio_url`** | Same shot, swap `audio_url` per language |
| Multi-modal — image + reference video + reference audio together | **Seedance 2.0 Pro** | Up to 9 image refs, 3 video refs (2–15s each), 3 audio refs |
| Brand-consistent narrative with character ref + scene ref + voice ref | **Seedance 2.0 Pro** | Image holds identity, video holds scene, audio holds voice |
| Default if unspecified | **HappyHorse 1.0 I2V** | Best all-round quality + native audio |

The agent reads this table, classifies the user's intent, and picks the matching subsection below.

## Prerequisites

1. **RunComfy CLI** — `npm i -g @runcomfy/cli`

4. **A source image URL** — JPEG/PNG/WebP, min 300px, ≤10MB; aspect 1:2.5 to 2.5:1 (HappyHorse) — other models have similar specs.
