图生视频（i2v）。固定 FAST 模式，无 speed 维度；不支持纯文生视频（t2v），必须给首帧。时长固定约 5 秒。

项目	内容
action	`VIDEO`
计费	`midjourney@video` / `midjourney@video-720p`，实扣 = 单价 × `batch_size`
必填	`image_urls`（首帧）或 `task_id`（复用 imagine SUCCESS）

参数

字段	类型	必填	默认	说明
`prompt`	string	否	（继承父任务）	视频提示词；为空时必须有 `task_id`
`image_urls`	string[]	△	—	起始帧（1 张，≤ 12 MiB）；与 `task_id` 二选一
`task_id`	string	△	—	复用已有 imagine SUCCESS；与 `image_urls` 二选一
`index`	int	否	—	从 imagine 4 张图选哪张作首帧（`0`–`3`，配合 `task_id`）
`video_type`	string	否	`vid_1.1_i2v_480`	分辨率档（见下表）；含 `720` → 走 `@video-720p` 计费
`animate_mode`	string	否	`manual`	`manual` / `auto`；`auto` 必须给 `task_id` + `index`
`motion`	string	否	`high`	`low` / `high`；运动幅度，不影响计费
`batch_size`	int	否	`1`	必须 `1` / `2` / `4`，其他值视为 1；计费 × N
`end_url`	string	否	—	结束帧；设了后 `video_type` 自动升级为 `start_end_*`

video_type 合法值

值	分辨率	模式	命中价格
`vid_1.1_i2v_480`	480p	基础 i2v（默认）	`midjourney@video`
`vid_1.1_i2v_720`	720p	基础 i2v	`midjourney@video-720p`
`vid_1.1_i2v_start_end_480`	480p	起止帧（传 `end_url` 时自动升级）	`midjourney@video`
`vid_1.1_i2v_start_end_720`	720p	起止帧（传 `end_url` 时自动升级）	`midjourney@video-720p`

不接受带 extend 的取值；仅支持上表列出的 video_type。

请求示例

简单 i2v（自带首帧，batch 4）：

{
  "prompt": "the cat slowly turns its head to the camera",
  "image_urls": ["https://example.com/cat.png"],
  "motion": "high",
  "batch_size": 4
}

起止帧 transition（传 end_url 自动升级为 start_end）：

{
  "prompt": "transition smoothly from sunrise to sunset",
  "image_urls": ["https://example.com/sunrise.jpg"],
  "end_url": "https://example.com/sunset.jpg",
  "video_type": "vid_1.1_i2v_720"
}

响应

提交返回 task_id，轮询 GET /v1/tasks/{task_id}。SUCCESS 后含 video_url（首个）+ video_urls（length === batch_size，batch=1 时也是 1 个元素）：

{
  "id": "task_xxx",
  "status": "SUCCESS",
  "action": "VIDEO",
  "mode": "FAST",
  "video_url": "https://r2.example.com/video-0.mp4",
  "video_urls": [
    "https://r2.example.com/video-0.mp4",
    "https://r2.example.com/video-1.mp4"
  ]
}

注意

不支持纯文生视频（t2v）：必须给 image_urls 或 task_id，否则返回 400；两者不能同时传。
固定 FAST 模式，无 speed 维度（计费表里 @video-fast / @video-turbo 永不命中）。
batch_size 严格校验为 1 / 2 / 4；batch=4 实扣 4 倍，预算敏感时用 batch=1。
animate_mode=auto 必须同时给 task_id + index。
首帧 / 结束帧单图 ≤ 12 MiB。
