Vidu Q1 Reference to Videos generates videos using a reference image and text description. It supports various subjects, such as characters and objects. By uploading multiple perspectives of a subject, you can create videos that maintain visual consistency.

This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the [Task Result API](/docs/api-reference/model-apis-task-result) to retrieve the video generation results.

##

[​](#request-headers)

Request Headers

[​](#param-content-type)

Content-Type

string

required

Supports: `application/json`

[​](#param-authorization)

Authorization

string

required

Bearer authentication format, for example: Bearer {{API Key}}.

##

[​](#request-body)

Request Body

[​](#param-images)

images

string[]

required

The model will use the provided images as references to generate a video with consistent subjects.For fields that accept images:

- Accepts 1 to 7 images

- Images Assets can be provided via URLs or Base64 encode

- You must use one of the following codecs: PNG, JPEG, JPG, WebP

- The dimensions of the images must be at least 128x128 pixels

- The aspect ratio of the images must be less than 1:4 or 4:1

- All images are limited to 50MB

- The length of the base64 decode must be under 10MB, and it must include an appropriate content type string. For instance:

```
data:image/png;base64,{base64_encode}
```

[​](#param-prompt)

prompt

string

required

Text prompt for video generation, with a maximum length of 1500 characters.

[​](#param-duration)

duration

integer

Video duration in seconds. The default is 5 seconds, with `5` being the only available option.

[​](#param-seed)

seed

integer

Random seed for video generation.

- Defaults to a random seed number

- Manually set values will override the default random seed

[​](#param-aspect-ratio)

aspect_ratio

string

The aspect ratio of the output video. Default: `16:9`

Accepted values: `16:9`, `9:16`, `1:1`

[​](#param-resolution)

resolution

string

Output video resolution. Default is 1080p, with `1080p` as the only option available.

[​](#param-movement-amplitude)

movement_amplitude

string

The movement amplitude of objects in the frame. Default: `auto`

Accepted values: `auto`, `small`, `medium`, `large`

[​](#param-bgm)

bgm

boolean

Whether to add background music to the generated video. Default: `false`

Acceptable values: `true`, `false`When true, the system will automatically add a suitable BGM. BGM has no time limit and the system automatically adapts.

##

[​](#response)

Response

[​](#param-task-id)

task_id

string

required

Use the task_id to request the [Task Result API](/docs/api-reference/model-apis-task-result) to retrieve the generated outputs.
