}Veo3.1-Lite 视频生成
- Veo 3.1 Lite 是 Veo 3.1 的低价档:支持文生视频、首帧 / 首尾帧图生视频;不支持参考图和
4k - 按输出视频秒数计费,单价取决于清晰度和是否生成音频,价格见 EvoLink 模型价格
- 异步处理模式,使用返回的任务ID 进行查询
- 生成的视频链接,有效期为24小时,请尽快保存

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
请求体
视频生成模型名称。本模型不接受 image_start、image_end 和 model_params(返回 400)
veo-3.1-lite-generate-preview "veo-3.1-lite-generate-preview"
描述视频的提示词,最多 2000 tokens。按 cl100k 计数;token 数不等于字符数. Google 官方支持的提示词语言为英语。EvoLink 不按提示词语言拒绝请求;其他语言的生成效果不作保证.
"A golden retriever puppy running through a sunlit meadow, slow motion, cinematic lighting"
输入图像URL列表,用于图生视频功能
注意:
- 单次请求最多支持
2张图像:1张作为首帧,2张作为首尾帧 - 图像大小:不超过
10 MB - 支持的文件格式:
.jpg、.jpeg、.png
2["https://example.com/first-frame.jpg"]
视频生成模式,不传时按图像数量自动匹配:
TEXT:文本生视频(传了图像也不会使用)FIRST&LAST:首尾帧生视频,可传入1~2张图像
本模型不支持 REFERENCE(参考图生视频),传入返回 400
TEXT, FIRST&LAST 视频宽高比。auto 等同于不传 aspect_ratio:不指定比例,由模型决定
auto, 16:9, 9:16 是否生成音频,默认为true。生成音频会提高每秒单价
视频时长(秒),默认为4,时长越长费用越高
4, 6, 8 生成视频数量,默认为1,每个视频单独计费
1 <= x <= 4视频分辨率,默认为720p。1080p 每秒单价更高;本模型不支持 4k
720p, 1080p 随机种子,用于复现生成结果
1 <= x <= 4294967295负面提示词,描述不希望在视频中出现的内容
人物生成控制。不传时使用上游默认值 allow_adult。allow_adult:仅允许生成成人;dont_allow:禁止生成包含人物或人脸的视频
allow_adult, dont_allow 图生视频的图像调整模式。不传时使用上游默认值 pad。pad:补边以适配输出比例;crop:居中裁切以适配输出比例。仅在提供输入图像时允许传入,无图时传入返回 400
pad, crop 任务完成后的HTTPS回调地址
回调时机:
- 任务完成(completed)或失败(failed)时触发
- 在计费确认完成后发送
安全限制:
- 仅支持HTTPS协议
- 禁止回调到内网IP地址(127.0.0.1、10.x.x.x、172.16-31.x.x、192.168.x.x等)
- URL长度不超过
2048UTF-8 字节
回调机制:
- 超时时间:
10秒 - 失败后最多重试
3次(会分别在失败的1秒/2秒/4秒后进行重试) - 回调响应体格式与任务查询接口返回的格式一致
- 回调地址若返回2xx状态码视为成功,其他状态码会触发重试
