An advanced AI framework from ByteDance that generates realistic lip-sync videos from a single image and motion signals (audio). It supports multiple visual and audio styles and produces videos in any body proportion, with realism enhanced by motion, lighting, and texture details.

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 both corresponding API schemas.
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.

Body
modelstring · enumRequiredPossible values:
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.
audio_urlstring · uriRequired
The URL of the audio file for lip-sync animation. The model detects spoken parts and syncs the character's mouth to them. Audio must be under 30s long.

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 completed, the response will include the final result — with the generated video URL and additional metadata.
