认证

Authorizationstring必填

所有接口均需要使用 Bearer Token 进行认证

获取 API Key:

访问 API Key 管理页面 获取您的 API Key

使用时在请求头中添加:

Authorization: Bearer YOUR_API_KEY

请求参数

modelstring必填

视频生成模型名称

支持的模型:

  • veo3.1-fast-official - Veo 3.1 官方快速版
  • veo3.1-quality-official - Veo 3.1 官方高质量版
nsfw_checkboolean默认 false

是否在提交视频任务前执行内容审核。

  • true:使用 omni-moderation-latest 审核提示词和输入图片
  • false 或不传:不发起审核请求,不增加审核成本与延迟(默认)
promptstring必填

正向文本提示词

建议详细描述场景、动作、风格等,以获得更好的生成效果。建议使用英文提示词。

示例:"a golden retriever running on the beach, sunset, cinematic"

negative_promptstring

负面提示词,用于排除不想要的内容

示例:"blurry, low quality, watermark, text"

durationinteger默认 8

视频时长(秒)

建议使用:4 / 6 / 8

默认值:8

⚠️ 注意: 必须输入纯数字(如 8),不要加引号,否则会报错

aspect_ratiostring默认 16:9

视频宽高比

可选值:

  • 16:9 - 横屏
  • 9:16 - 竖屏

默认值:16:9

resolutionstring默认 720p

视频分辨率

可选值:

  • 720p - 标准分辨率
  • 1080p - 高清分辨率
  • 4K - 超高清分辨率

默认值:720p

first_frame_imagestring

首帧图片 URL,用于图生视频

  • 图片 URL 必须公开可访问,不能有防盗链
  • 建议使用对象存储 URL,而非临时下载地址
last_frame_imagestring

尾帧图片 URL,用于图生视频

与 first_frame_image 配合使用,实现首尾帧控制

seedinteger

随机种子,用于复现生成结果

取值范围:0 - 4294967295

sample_countinteger默认 1

生成样本数量 1-4,当前建议填 1

默认值:1

generate_audioboolean默认 false

是否生成音频轨道

person_generationstring默认 allow_adult

人物生成策略

可选值:

  • allow_adult - 只允许生成成人人物/成人面孔
  • disallow - 不允许生成人物或人脸

默认值:allow_adult

resize_modestring默认 pad

图片缩放策略(图生视频时生效)

可选值:

  • pad - 填充模式
  • crop - 裁剪模式

默认值:pad

enhance_promptboolean默认 true

是否启用上游提示词增强

默认值:true

  • 该参数只能设置为 true,设置为 false 会导致请求报错
  • 如不需要此参数,请勿传入

文生视频 vs 图生视频

系统通过是否传入图片参数自动判断模式:不传图片为文生视频,传图片为图生视频。

参数 文生视频 图生视频
prompt ✅ 必填 ✅ 必填
first_frame_image ❌ 不传 ✅ 至少传一个
last_frame_image ❌ 不传 ✅ 可选(尾帧)
negative_prompt ✅ 可选 ✅ 可选
duration ✅ 可选 ✅ 可选
aspect_ratio ✅ 可选 ✅ 可选
resolution ✅ 可选 ✅ 可选
seed ✅ 可选 ✅ 可选
generate_audio ✅ 可选 ✅ 可选
person_generation ✅ 可选 ✅ 可选
resize_mode ❌ 不适用 ✅ 可选
enhance_prompt ✅ 可选 ✅ 可选
