## What it does

The skill sends video-generation jobs from text prompts or images, creates transitions between two frames, and builds scenes from references. It also supports VACE and videoedit workflows. Jobs run asynchronously: a script submits each request, checks its status, and downloads the result.

The package includes `scripts/video.py` and reference files covering request fields, prompt patterns, workflows, and media operations with ffmpeg or moviepy. You need Python 3.9+, `curl`, and an API key. Token Plan keys work with models from that plan’s catalog; for i2v, r2v, and kf2v, reference media must be supplied through accessible URLs rather than local files.

The kf2v mode has a fixed 5-second duration and produces silent video; other durations fail. Check the current model catalog before choosing parameters, since size and aspect-ratio fields differ between model families.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-video-generation -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/qianwen-video-generation/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/qianwen-video-generation/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-video-generation -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/qianwen-video-generation/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-video-generation -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/qianwen-video-generation/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install QianWen-AI/qianwen-ai qianwen-video-generation
```

2. **Manually: put the files in place**
- File: `.github/skills/qianwen-video-generation/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-video-generation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/QianWen-AI/qianwen-ai --path skills/video/qianwen-video-generation
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/qianwen-video-generation/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add QianWen-AI/qianwen-ai --skill qianwen-video-generation -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/QianWen-AI/qianwen-ai/tree/HEAD/skills/video/qianwen-video-generation/SKILL.md

## When to use it
- generate a clip from a text prompt
- animate a still image
- create a transition between two frames
- stage a new scene using character references
- edit or extend an existing video

## Example prompts
- Generate a video from this prompt: a rainy city at night, with the camera moving slowly forward.
- Animate `portrait.png` and keep the character in frame.
- Create a silent 5-second transition from `start.png` to `end.png`.

# Qwen Video Generation

Generate videos using Wan and HappyHorse models. All tasks are **asynchronous** — submit, then poll until
completion.
This skill is part of **QianWen-AI/qianwen-ai**.

> **⚠️ Critical Parameter Differences:**
> - **kf2v (First+Last Frame)**: Duration is **fixed at 5 seconds** — other values will fail. Output is **silent only**.
> - **Resolution parameters vary by model family, not mode alone**: Check the current model catalog before choosing `size`, `resolution`, or `ratio`. For example, `happyhorse-1.1-t2v` uses `resolution` + `ratio`, while `wan2.6-t2v` uses `size`.

## Skill directory

Use this skill's internal files to execute and learn. Load reference files on demand when the default path fails or you need details.

| Location | Purpose |

| `references/execution-guide.md` | Fallback: curl for all 5 modes, code generation |
| `references/request-fields.md` | Field tables and audio handling by mode |

## Security

**NEVER output any API key or credential in plaintext.** Always use variable references (`$DASHSCOPE_API_KEY` in shell, `os.environ["DASHSCOPE_API_KEY"]` in Python). Any check or detection of credentials must be **non-plaintext**: report only status (e.g. "set" / "not set", "valid" / "invalid"), never the value. Never display contents of `.env` or config files that may contain secrets.
