avatar-standard
From a single image and a voice track, this model generates expressive character animations aligned with the speech’s rhythm, intonation, and meaning. This version outputs 720p video at 24 fps.

How to Make a Call
API Schemas
Create a video generation task and send it to the server
You can create a video with this API by providing a reference image of a character and an audio file. The character will deliver the audio with full lip-sync and natural gestures. This POST request creates and submits a video generation task to the server — and returns a generation ID.
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.
The URL of the audio file. Supported formats: MP3, WAV, M4A, AAC. Maximum file size: 5 MB.
The text description of the scene, subject, or action to generate in the video.

Retrieve the generated video from the server
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 generation_id, obtained from the endpoint described above. If the video generation task status is complete, the response will include the final result — with the generated video URL and additional metadata.

Full Example: Generating and Retrieving the Video From the Server
The code below creates a video generation task, then automatically polls the server every 10 seconds until it finally receives the video URL.

Original (1280x720, with sound):
The following video was generated by adding just one line to our example:
"prompt": "A person speaking playfully, laughing frequently and gesturing wildly."prompt: 'A person speaking playfully, laughing frequently and gesturing wildly.',See how dramatically the prompt parameter can change the character’s behavior and mannerisms:
"prompt": "A person speaking playfully, laughing frequently and gesturing wildly."Last updated
