Frame-by-frame detection
Detection runs on every frame, so faces and (optionally) license plates stay blurred continuously, even as they move through the shot.
CatalogLatency Depends on video duration and resolution. Typically ~0.5–2× real-time duration. Async true Rate Limit Per API key Max Input Up to 4096px resolution per frame.

Overview
Send a video URL and the service detects faces (and, if you ask, license plates) on every frame and blurs them throughout the clip — even as people and vehicles move. Faces are blurred by default; set detect_lp to true to blur license plates as well. This is an async job: submit it, poll until it's completed, then download the blurred video. The original audio is preserved.
Key capabilities
Choose what to blur
Faces are blurred by default. Set detect_lp to true to also blur license plates, or turn faces off to blur plates only.
Audio preserved
The original audio track is kept in the blurred output video.
Async processing
Submit the job, get a job_id back, poll GET /v2/jobs/{job_id} until it's completed, then download the blurred video.
When to use it
Privacy-compliant video publishing
Anonymize all faces in footage before publishing to comply with GDPR and other privacy regulations.
Witness and source protection
Blur faces of witnesses, informants, or sources in journalistic or legal video content.
Training data anonymization
Blur faces and plates in video datasets before sharing or publishing.
Surveillance footage redaction
Redact identities in security camera footage for sharing with third parties.

Guides & tips
How it works
- Detection runs on every frame of your video, finding faces (and license plates when detect_lp=true) wherever they appear.
- Each detected region is blurred, frame after frame, so it stays covered even as it moves.
- The frames are reassembled with the original audio preserved, and the finished video is returned as a URL in result_data when the job completes.
What gets blurred
- Faces are detected and blurred by default (detect_faces=true).
- Set detect_lp=true to also blur vehicle license plates in the same pass.
- To blur plates only, set detect_faces=false and detect_lp=true.
Getting your result
- After submitting, save the job.id from the response.
- Poll GET /v2/jobs/{job_id} every 5–10 seconds until status is completed.
- When it's completed, read result_data.data.url for the blurred video URL.
- If status is failed, the response includes the reason.
- Processing typically takes about 0.5–2× the video's duration, depending on resolution.
