# Qwen / Wan Video (DashScope) — 文生视频

This skill provides simple CLI scripts to:
1) submit an async Wan t2v job
2) poll task status until SUCCEEDED/FAILED
3) download the resulting mp4

## Requirements

- Set API key:

```bash
export DASHSCOPE_API_KEY="sk-..."
```

## Quick start (one command)

Generate a video and download to Windows Desktop (WSL2):

```bash
bash {baseDir}/scripts/generate.sh \
  --prompt "4秒赛博朋克雨夜城市镜头，霓虹反射，电影感镜头运动，高清" \
  --duration 4 \
  --size 1280*720 \
  --out "/mnt/c/Users/<USERNAME>/Desktop/wan_video.mp4"
```

## Submit only (returns task_id)

```bash
bash {baseDir}/scripts/submit.sh --prompt "..." --duration 4 --size 1280*720
```

## Poll status only

```bash
bash {baseDir}/scripts/poll.sh --task-id "<task_id>"
```

## 高级功能

### 多镜头叙事 (Multi-shot)

仅 wan2.6 系列模型支持此功能。通过设置 `prompt_extend: true` 和 `shot_type: "multi"` 启用。

```bash
curl --location 'https://dashscope.aliyuncs.com/api/v1/services/aigc/video-generation/video-synthesis' \
  -H 'X-DashScope-Async: enable' \
  -H "Authorization: Bearer $DASHSCOPE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "wan2.6-t2v",
    "input": {
      "prompt": "史诗级战斗场景..."
    },
    "parameters": {
      "size": "1280*720",
      "prompt_extend": true,
      "duration": 10,
      "shot_type": "multi"
    }
  }'
```

### 自动配音 (Auto Audio)

仅 wan2.6 和 wan2.5 系列模型支持。若不提供 `input.audio_url`，模型将根据视频内容自动生成匹配的背景音乐或音效。

```bash
curl --location 'https://dashscope.aliyuncs.com/api/v1/services/aigc/video-generation/video-synthesis' \
  -H 'X-DashScope-Async: enable' \
  -H "Authorization: Bearer $DASHSCOPE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "wan2.5-t2v-preview",
    "input": {
      "prompt": "史诗级战斗场景..."
    },
    "parameters": {
      "size": "832*480",
      "prompt_extend": true,
      "duration": 10
    }
  }'
```
