This text-to-video model generates videos up to 1080p and can voice a character with full lip-sync by providing dialogue directly in the prompt parameter. In addition to the features of the Wan 2.5 Preview (Text-to-Video) model, it also supports uploading a reference image, which may depict the character to be animated or the surrounding scene.

How to Make a Call
Step-by-Step Instructions
Generating a video using this model involves sequentially calling two endpoints:
The first one is for creating and sending a video generation task to the server (returns a generation ID).
The second one is for requesting the generated video from the server using the generation ID received from the first endpoint.
Below, you can find two corresponding API schemas and examples for both endpoint calls.
API Schemas
Now, all of our API schemas for video models use our new universal short URL — https://api.aimlapi.com/v2/video/generations.
However, you can still call this model using the legacy URL that includes the vendor name.
Video Generation
This endpoint creates and sends a video generation task to the server — and returns a generation ID.

Body
modelstring · enumRequiredPossible values:
promptstringRequired
The text description of the scene, subject, or action to generate in the video.
image_urlstring · uriRequired
A direct link to an online image or a Base64-encoded local image that will serve as the visual base or the first frame for the video.
resolutionstring · enumOptional
An enumeration where the short side of the video frame determines the resolution.
Default: 1080pPossible values:
aspect_ratiostring · enumOptional
The aspect ratio of the generated video.
Default: 16:9Possible values:
durationinteger · enumOptional
The length of the output video in seconds.
Default: 10Possible values:
negative_promptstringOptional
The description of elements to avoid in the generated video.
seedintegerOptional
Varying the seed integer is a way to get different results for the same other request parameters. Using the same value for an identical request will produce similar results. If unspecified, a random number is chosen.
enhance_promptbooleanOptional
Whether to enable prompt expansion.
Default: true
Responses
200Success
application/json
idstringRequired
The ID of the generated video.
Example: 60ac7c34-3224-4b14-8e7d-0aa0db708325
statusstring · enumRequired
The current status of the generation task.
Example: completedPossible values:
post
/v2/video/generations
200Success
Fetch the video
After sending a request for video generation, this task is added to the queue. This endpoint lets you check the status of a video generation task using its id, obtained from the endpoint described above.
If the video generation task status is completed, the response will include the final result — with the generated video URL and additional metadata.
