Why use Reusable LipSync API?
The Reusable LipSync API is an optimized version of our LipSync API, designed for developers who frequently generate lip-synced videos using the same visual reference.What’s Different?
Inputs and outputs
Create a reusable model
Output:
model_id for the reusable LipSync model.
Generate with a reusable model
Output: lip-synced video URL.
How it works
1
Create a reusable LipSync model
Create a reusable model from a compatible previous LipSync job.
2
Prepare the driving audio or text
Host your audio at a publicly accessible URL, or provide text to synthesize speech using the cloned voice.
3
Send a generation request
Provide the required inputs and any optional settings needed for the job.
4
Wait or query status
Use our webhook callback or poll the API with your job ID until processing is complete.
5
Download video output
Retrieve the finished talking photo or lip‑synced video from the provided URL.
Usage Limitation:
- The default concurrency limit is 10 jobs. The limit is shared by all members of a team. See Concurrency limits for details.
- Estimated queue time: 1–120 minutes, depending on system load.
- Processing time: ~10 minutes.
If a video or photo contains multiple faces, only the largest detected face will be lip‑synced.
Model Expiration Policy
Models created via the Model Creation API have an automatic expiration mechanism based on activity.Rules
- Default Expiration Period Each reusable lipsync model remains active for 3 months from its creation date or last usage.
- Automatic Extension Every time the reusable lipsync model is used (e.g., called in a reusable lipsync api request), its expiration date is extended by another 3 months from that point in time.
- Expiration If a reusable lipsync model is not used for 3 consecutive months, it will automatically expire and may be deleted permanently.
- Reactivation Expired reusable lipsync models cannot be reactivated. To continue using the same configuration, you must resubmit the lipsync job and recreate reusable lipsync model through the API.
