Seedance 视频生成
使用字节跳动 Seedance-1.5-pro 模型 (doubao-seedance-1-5-pro-251215) 根据文本或图片生成视频。
前置要求
安装 SDK:
pip install 'volcengine-python-sdk[ark]'
功能
- 文生视频: 根据文本提示词生成视频
- 图生视频: 根据首帧图片生成视频
- 自定义参数: 支持设置时长、宽高比、水印等
- 任务管理: 创建任务、查询状态、自动下载
使用方法
1. 快速生成视频 (文生视频)
cd ~/.openclaw/workspace/skills/seedance-video
python3 scripts/generate_video.py "一只可爱的猫咪在草地上玩耍" --wait -o cat.mp4
2. 自定义参数
python3 scripts/generate_video.py "日落时分的海边" \
--duration 10 \
--ratio 16:9 \
--wait \
-o sunset.mp4
3. 图生视频
python3 scripts/generate_video.py "猫咪动起来" \
--image-url https://example.com/cat.jpg \
--duration 5 \
--wait
4. 仅创建任务（不等待）
python3 scripts/generate_video.py "星空下的城市" -o starry.mp4
# 返回任务ID
然后稍后查询状态并下载：
python3 scripts/generate_video.py --status <task_id> --wait -o starry.mp4

-d, --duration | 5 | 视频时长(秒) |
-r, --ratio | 16:9 | 宽高比 (16:9, 9:16, 1:1, 4:3 等) |
--watermark | false | 添加水印 |
--return-last-frame | false | 返回最后一帧图片 |

配置方式（推荐）
- 复制配置模板：
cp .canghe-skills/.env.example .canghe-skills/.env
- 编辑
.canghe-skills/.env文件，填写你的 API Key：
ARK_API_KEY=your-actual-api-key-here
或使用环境变量
export ARK_API_KEY="your-api-key"
# 或
export SEEDANCE_API_KEY="your-api-key"
加载优先级
- 系统环境变量 (
process.env) - 当前目录
.canghe-skills/.env - 用户主目录
~/.canghe-skills/.env
提示词优化建议
- 具体描述: 描述场景、主体、动作、环境等细节
- 风格明确: 指定摄影风格（如"电影感"、"纪录片风格"）
- 光线描述: 说明光线条件（如"黄金时刻"、"柔和自然光"）
- 镜头语言: 描述镜头运动（如"缓慢推进"、"稳定器拍摄"）
示例提示词
一只金毛犬在秋天的公园里奔跑，金色落叶飘落，下午的阳光透过树叶，电影感镜头，稳定器拍摄，4K画质
一个机器人在未来城市的霓虹灯街道上行走，赛博朋克风格，雨夜，倒影，广角镜头，电影色调
Python API 使用
from volcenginesdkarkruntime import Ark
from scripts.generate_video import create_video_task, wait_for_video
# 初始化客户端
client = Ark(
base_url="https://ark.cn-beijing.volces.com/api/v3",
api_key="your-api-key"
)
# 创建视频任务
result = create_video_task(
client=client,
model="doubao-seedance-1-5-pro-251215",
prompt="一只鸟在天空中飞翔",
duration=5
)
task_id = result["task_id"]
# 等待并获取结果
final_status = wait_for_video(client, task_id)
video_url = final_status["video_url"]
注意事项
- 异步生成: 视频生成是异步过程，通常需要 30-60 秒
- 任务保存时间: 任务数据仅保留 24 小时
- 限流: 注意账号的 RPM 和并发数限制
- 视频比例: 建议视频宽高比与首帧图片比例接近
任务状态
queued: 排队中running: 生成中succeeded: 成功failed: 失败
