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:

export DASHSCOPE_API_KEY="sk-..."

Quick start (one command)

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

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 1280720 \
  --out "/mnt/c/Users//Desktop/wan_video.mp4"

Submit only (returns task_id)

bash {baseDir}/scripts/submit.sh --prompt "..." --duration 4 --size 1280720

Poll status only

bash {baseDir}/scripts/poll.sh --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。

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": "1280720",
      "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。

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": "832480",
      "prompt_extend": true,
      "duration": 10
    }
  }'

传入音频文件 (Custom Audio)

仅 wan2.6 和 wan2.5 系列模型支持。通过 input.audio_url 参数传入自定义音频的 URL。

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...",
      "audio_url": "https://example.com/audio.mp3"
    },
    "parameters": {
      "size": "832480",
      "prompt_extend": true,
      "duration": 10
    }
  }'

生成无声视频 (Silent Video)

仅 wan2.2 和 wanx2.1 系列模型支持生成无声视频。默认生成无声视频，无需设置。

wan2.6 及 wan2.5 系列模型默认生成有声视频。

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": "wan2.2-t2v-plus",
    "input": {
      "prompt": "低对比度，复古70年代风格地铁站..."
    },
    "parameters": {
      "size": "832480",
      "prompt_extend": true
    }
  }'

使用反向提示词 (Negative Prompt)

通过 negative_prompt 排除不需要的元素。

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": "wan2.2-t2v-plus",
    "input": {
      "prompt": "一只小猫在月光下奔跑",
      "negative_prompt": "花朵"
    },
    "parameters": {
      "size": "832*480"
    }
  }'
