Description Initiates an asynchronous object erasure job. Removes objects defined by the mask input and reconstructs the background.

Mask Input

This endpoint requires a mask definition object. You can provide a direct mask_url, or use one of our masking endpoints (mask_by_prompt, mask_by_key_points) to define the mask area.

Response behavior:

• Returns HTTP 202 with request_id and status_url

• Check job status by polling status_url or by calling the status endpoint with the request_id until a terminal status is returned

Constraints & Limits:

• Max Duration: 5 seconds. Videos longer than 5s will be truncated if auto_trim is true, or rejected if false.

• Max Resolution: 750p. Inputs higher than 750p will be automatically downscaled.

• Frame Rate: Recommended 24 FPS (preserved in output).

Preservation Rules:

• Aspect Ratio (within 16:9 constraint)

• Frame Rate

• Audio (preserved by default)
