Generate videos using Alibaba Cloud DashScope Wan (通义万相) text-to-video (t2v) API (e.g., wan2.6-t2v). Use when the user asks to create a short video from a text prompt via 百炼/通义万相/wan 文生视频, and wants the agent to submit an async task, poll status, and download the mp4 locally (e.g., to Windows Desktop from WSL2).
This skill provides simple CLI scripts to:
export DASHSCOPE_API_KEY="sk-..."
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 1280*720 \
--out "/mnt/c/Users/<USERNAME>/Desktop/wan_video.mp4"
bash {baseDir}/scripts/submit.sh --prompt "..." --duration 4 --size 1280*720
bash {baseDir}/scripts/poll.sh --task-id "<task_id>"
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": "1280*720",
"prompt_extend": true,
"duration": 10,
"shot_type": "multi"
}
}'
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": "832*480",
"prompt_extend": true,
"duration": 10
}
}'
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": "832*480",
"prompt_extend": true,
"duration": 10
}
}'
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": "832*480",
"prompt_extend": true
}
}'
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"
}
}'
