# Grok Imagine Video

> 使用 `POST /v1/videos` 调用 `grok-imagine-video` 提交 JSON 视频生成任务。

# Grok Imagine Video

`grok-imagine-video` 是 Grok Imagine 系列的视频生成模型。该模型使用 JSON 请求体，支持文生视频和参考图视频生成。

* 接口路径是 `POST /v1/videos`。
* 请求格式是 `application/json`。
* 文生视频只需要 `model`、`prompt`、`seconds`、`aspect_ratio`、`resolution`。
* 图生视频单图使用 `image`，多图使用 `images`。
* `resolution` 支持 `480P` 和 `720P`。
* `prompt` 最多支持 `4096` 个字符。

## 方法与路径

```http theme={null}

## 与 Grok 1.5 / 3 的区别

| 项目    | `grok-imagine-video` | `grok-video-1.5` / `grok-video-3` |
| ----- | -------------------- | --------------------------------- |
| 请求格式  | JSON                 | `multipart/form-data`             |
| 图片字段  | `image` / `images`   | `input_reference`                 |
| 清晰度字段 | `resolution`         | `size`                            |
| 清晰度值  | `480P`、`720P`        | `480P`、`540P`、`720P`、`1080P`      |
| 时长规则  | 自定义秒数，最小 `1s`        | `10s` 对应 Pro 档，`15s` 对应 Max 档     |
