参数说明

字段类型是否必传示例说明
start_framestring条件必传https://.../start.jpg首帧图片 URL;与 ref_img_urlref_resources 至少传一种
end_framestringhttps://.../end.jpg尾帧图片 URL;传入后参考图片总数仍不能超过 2 张
ref_img_urlarray<string>条件必传["https://.../start.jpg", "https://.../end.jpg"]兼容参考图 URL 列表,可替代 start_frameend_frame
ref_resourcesarray<object>条件必传[{"url":"https://.../start.jpg","file_type":"image"}]参考图片列表,可替代 start_frameend_frame
ref_resources.urlstringhttps://.../start.jpg可公开访问的参考图片 URL
ref_resources.file_typestringimage该模式固定传 image
ref_promptstring镜头从首帧自然过渡到尾帧视频生成提示词
creation_typeint4创作类型,固定为 4
aspect_ratiostringauto输出视频宽高比,支持 auto16:94:31:13:49:1621:9
clarityint720输出清晰度,支持 4807201080
video_durationint5输出视频时长(秒),支持 3-30 的整数
number_of_imagesint1生成数量,固定为 1
model_codestringseedance-2.5-first-last-to-video模型编码,固定为 seedance-2.5-first-last-to-video
