# Seedance 2.5 图生视频

> - Seedance 2.5 图生视频模型，使用一张首帧图片和文本提示词生成视频
- 支持 `480p`、`720p`、`1080p` 分辨率和 `4`–`30` 秒整数时长
- `image_url` 必须是公开可访问的图片 URL
- 异步处理模式，使用返回的任务ID [进行查询](/pages/zh/api-manual/task-management/get-task-detail)
- 结果中的 `results[i].url` 是统一视频 URL；任务原始结果和视频元数据会保留在 `results[i].result`、`video_url`、`videoUrls`、`resultUrls`、`outputs` 等字段中，详见 [任务查询特殊格式说明](/pages/zh/api-manual/task-management/get-task-detail#特殊格式)
