Required
Description
model
String
Required
Model name
Accepted values: viduq3-turbo viduq3-pro , viduq2-pro-fast, viduq2-pro , viduq2-turbo , viduq1 , viduq1-classic , vidu2.0
-viduq3-turbo: Compared to viduq3-pro, the generation speed is faster
-viduq3-pro: Supports audio-video synchronization, supports storyboard video generation
-viduq2-pro-fast: Fast speed, low price, stable quality
-viduq2-pro: New model with excellent performance
-viduq2-turbo: New model with good effect, fast generation
-Viduq1: Clear image, smooth transition, stable camera operation
-Viduq1 classical: Clear image, richer transitions and camera movements
-Vidu2.0: Fast generation speed
images
Array[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 post body of the HTTP request should not exceed 20MB, and it must include an appropriate content type string. For instance, 
data:image/png;base64,{base64_encode}
prompt
String
Optional
Prompt description, max 5000 characters.
Note：If the is_rec parameter for recommended prompts is used, the model will ignore the manually entered prompt for this parameter.
is_rec
Bool
Optional
Whether to use the recommended prompt.
- true: Yes, the system will automatically generate and apply a recommended prompt to create the video. The number of recommended prompts = 1.
- false: No, the video will be generated based on the user-provided prompt.
Note: When the recommended prompt feature is enabled, each task will consume an additional 10 credits.
duration
Int
Optional
Video duration. Default values vary by model:
- viduq3-pro , viduq3-turbo ：default 5s，available: 1 - 16
- viduq2-pro-fast , viduq2-pro , viduq2-turbo ：default 5s，available: 1 - 8
- viduq1 and viduq1-classic: default 5s, available: 5
- vidu2.0 : default 4s, available: 4, 8
seed
Int
Optional
Random seed
- Defaults to a random seed number
- Manually set values will override the default random seed
resolution
String
Optional
Resolution (based on model & duration):
- viduq3-pro , viduq3-turbo (1 - 16s)：default 720p, options: 540p, 720p, 1080p
- viduq2-pro-fast (1 - 8s): default 720p, options: 720p, 1080p
- viduq2-pro , viduq2-turbo (1 - 8s): default 720p, options: 540p, 720p, 1080p
- viduq1 and viduq1-classic(5s): default 1080p, options: 1080p
- vidu2.0 (4s): default 360p, options: 360p, 720p, 1080p
- vidu2.0 (8s): default 720p, options: 720p
movement_amplitude
String
Optional
The movement amplitude of objects in the frame
Defaults to auto, accepted value: auto small medium large
This parameter does not take effect when using the q2 & q3 model
bgm
Bool
Optional
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.
BGM does not take effect when the duration of the q2 model is 9 or 10 seconds
BGM does not available in q3 models
audio
Bool
Optional
Whether to use direct audio-video generation capability. Default: true. Enumerated values:
- false: No direct audio-video generation, outputs silent video
- true: Requires audio-video synchronization, outputs video with sound (including dialogue and sound effects)
Note 1: Only the q3 models supports this parameter
payload
String
Optional
transparent transmission parameters
No processing, only data transmission，with a maximum length of 1048576 characters
off_peak
Bool
Optional
off peak mode, Defaults to false, enum:
- true：off peak generate mode；
- false：normal generate mode；
- The off_peak mode consumes lower points, please refer to the details Pricing. Tasks submitted in off peak mode will be generated within 48 hours. Tasks that are not completed will be automatically cancelled and their points will be refunded. We also support cancel off_peak tasks.
- Except for q3, other direct audio-video generation functions
callback_url
String
Optional
Callback
When creating a task, you need to actively set the callback_url with a POST request. When the video generation task changes its status, Vidu will send a callback request to this URL, containing the latest status of the task. The structure of the callback request content will be the same as the return body of the GET Generation API.
The "status" in the callback response includes the following states:
- processing: Task is being processed.
- success: Task is completed (if sending fails, it will retry the callback three times).
- failed: Task failed (if sending fails, it will retry the callback three times).
Vidu uses a callback signature algorithm for verification, check out the details here: Callback Signature
