图生视频
更新时间：2025-12-01
本接口用于创建图生视频任务，包括：
- 单图生视频
- 首尾帧视频
- 参考生视频
- 智能多帧视频
注意事项：
-
V 相关模型图片尺寸大小格式限制
- 图片大小小于50M,格式只支持 JPG/JPEG/PNG, 图片长宽比需要小于1:4或者4:1
- 参考生任务时，图片尺寸不能小于 128*128，比例需要小于 1:16 或者 16:1
-
P 相关模型图片尺寸大小格式限制
- 图片尺寸最大支持 4000*4000
- 提示文本有最大长度限制， 其中 V15，V20，VQ1，VQ1C 为 1500 个字符，P35，P40, P45，P50 为 2048 字符，K16, K20，K21，K21M 为 2500 字符
- 图像 URL 需要确保公网可访问
