Vidu 2.0 Start End 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}}.

Request Body

images
string[]
required
Two images: first is start frame, second is end frame.Notes:
  1. Public URL or Base64
  2. Aspect ratios must be close: ratio between start/end frame must be in 0.8~1.25
  3. Format: png, jpeg, jpg, webp
  4. Max size: 50MB
  5. 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}
prompt
string
Prompt description, max 1500 characters.
duration
integer
Video duration in seconds. Default is 4 seconds, with options available for 4 or 8 seconds.
seed
integer
Random seed for video generation.
  • Defaults to a random seed number
  • Manually set values will override the default random seed
resolution
string
Resolution based on duration:
  • 4s: default 360p, options: 360p, 720p, 1080p
  • 8s: default 720p, options: 720p
movement_amplitude
string
The movement amplitude of objects in the frame. Default: auto
Accepted values: auto, small, medium, large
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

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