Vidu 2.0 Image to Video transforms static images into dynamic videos, incorporating creative storytelling and animations.
This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the Task Result API to retrieve the video generation results.

Request Headers

Content-Type
string
required
Supports: application/json
Authorization
string
required
Bearer authentication format, for example: Bearer {{API Key}}.

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

task_id
string
required
Use the task_id to request the Task Result API to retrieve the generated outputs.
