关于 Scail 2
接收一个参考角色 `image_url` 和一个展示人类、多人或动物的驱动 `video_url`。在 `animation` 模式下,角色执行驱动动作;在 `replacement` 模式下,角色替换主体并保留场景。分辨率为 512p 或 704p,方向根据图像选择。`driving_type` 可使用直接端到端驱动或明确的姿态骨架。
参数
发送规范名称或原生名称之一,不要同时发送两者。 规范名称
名称类型
默认值允许值
描述
prompt必填
类型string
指定所需输出视频的提示词。
image_url必填
image
类型url · image
提供要制作动画或替换主体的角色参考图像 URL;驱动视频决定动画或替换效果。
video_url必填
video
类型url · video
通过 URL 提供动作驱动视频,其中包含一个人、多人或动物。
mode可选
类型enum
默认值animation
animationreplacement
选择如何使用参考角色:`replacement` 保留原始场景,但将角色替换为驱动主体;`animation` 将驱动动作应用到角色。
driving_type可选
类型enum
默认值end_to_end
end_to_endpose
动画动作直接来自由 SAM3 使用 `end_to_end` 进行掩码处理的驱动视频;这是默认且推荐的选项,可获得最高稳健性。或者,`pose` 使用 NLF/DWPose 从该视频渲染显式骨架,在处理具有挑战性的输入时提供更高控制力。
subject_type可选
类型enum
默认值human
humananimal
驱动视频中的主体选择;使用 `animal` 时会将 SAM3 的检测提示词配置为非 `human` 主体。
resolution可选
类型enum
默认值512p
512p704p
输出分辨率,方向根据参考图像的宽高比自动确定。横向时,512p 映射为 896x512,704p 映射为 1280x704;纵向时分别使用 512x896 和 704x1280。
num_inference_steps可选
类型integer
默认值40
2 – 50
扩散采样步数。增加该值可提升质量,但需要更长时间。
guidance_scale可选
类型number
默认值5
1 – 10
无分类器指导强度,在遵循提示词和保持创意之间进行平衡。
shift可选
类型number
默认值3
1 – 10
流匹配的噪声调度偏移;使用 512p 时建议设置为 3.0。
seed可选
类型integer | null
响应中包含的生成种子;无论是显式提供,还是因输入为空而随机选择,都会返回。
enable_safety_checker可选
类型boolean
默认值true
调用方获得授权后,可将其设置为 false 以放宽审核。
必填
规范名称,也可接受
文件参数接受公开的 https:// URL、最大 10 MB 的 data: URI,或上传文件的 file_url。 文件

你的文件,由你选择每个 outputs[].url 都是存储中的副本:可永久保存(按 GB-月付费),也可免费保存 7 天,由账户设置或 ?storage= 决定。
每个模型的结构相同图像、视频和音频均包含 type、url、content_type、width、height 和 duration。output 是模型自身的结果对象。
输出字段
- video
- object {url, content_type, file_name, file_size}生成得到的视频文件。
- seed
- integer用于视频生成的种子。
- preprocessing_video
- object {url, content_type, file_name, file_size} | null包含提供给扩散模型的 Stage-A 姿态条件输入的调试视频,仅在 `output_preprocessing=true` 时可用。其内容取决于 `driving_type`:`end_to_end` 使用由 SAM3 掩码处理的驱动素材,而 `driving_type=pose` 使用由 NLF/DWPose 渲染的骨架。
- preprocessing_mask_video
- object {url, content_type, file_name, file_size} | null用于调试的 Stage-A 驱动掩码视频,仅在 `output_preprocessing=true` 时可用。
