Note for users in mainland China: Please use https://toapis.cn as the API endpoint (Base URL). Replace https://toapis.com with https://toapis.cn in the examples in this document.

Async task API, returns a task ID after submission
Supported models: viduq3-pro, viduq3-turbo, viduq3
viduq3-pro: High quality model, supports audio-video sync and storyboard generation
viduq3-turbo: Fast model, intelligent scene switching, fastest generation, best cost-effectiveness
viduq3: Best multi-camera consistency, intelligent camera switching, multi-reference generation

Use publicly accessible image URLs. Do not pass base64 image data in image_urls; upload local images with the Upload Image API first.

Authorization

string

required

All endpoints require Bearer Token authentication.

Authorization: Bearer YOUR_API_KEY

Request Parameters

string

required

Vidu Q3 model name.Options:

viduq3-pro - high quality, supports audio-video sync and storyboard generation
viduq3-turbo - fastest generation, intelligent scene switching
viduq3 - best multi-camera consistency, for multi-reference/subjects generation

string

required

Text prompt, maximum 5000 characters.Describes subject, action, scene, camera movement, and style. When using subjects, reference them via @name in the prompt.Example: "A cat playing piano, camera slowly zooms in, cinematic quality"

integer

default:"5"

Video duration in seconds.

viduq3-pro / viduq3-turbo: 1 to 16
viduq3: 3 to 16

string

default:"720p"

Video resolution.Options:

540p
720p
1080p

string

Video aspect ratio.Common values: 16:9, 9:16, 1:1Q3 models support any aspect ratio. When image_urls is provided, the output ratio is usually determined by the reference image.

string[]

Reference image URL array.

viduq3-pro / viduq3-turbo
- Omitted: text-to-video
- 1 image: image-to-video, image as first frame
- 2 images: first-last frame
viduq3
- Required, up to 7 reference images

Example: ["https://example.com/reference.jpg"]

boolean

Whether to enable audio-video output.

All Q3 models default to true

When true, the system generates speech and sound effects based on the prompt.

integer

Random seed for more reproducible results with the same parameters.

object

Extended parameters for fields supported by the upstream API but not exposed as top-level fields.

array

Subject list (Subjects mode, viduq3 only). Each subject contains name and images fields.

Up to 7 subjects
Up to 3 images per subject
Reference subjects via @name in the prompt

Example:

[
  {"name": "cat", "images": ["https://example.com/cat.jpg"]},
  {"name": "dog", "images": ["https://example.com/dog.jpg"]}
]

boolean

Whether to use intelligent entity library, defaults to false.

string

Voice ID for specifying the voice character in the video.

string

Audio type, effective when audio is true.Options:

all - sound effects + speech (default)
speech_only - speech only
sound-effect_only - sound effects only

boolean
