How to Redact PII from Videos Automatically

Images are straightforward to redact. Videos are harder. Every second of footage contains dozens of frames, each showing faces, license plates, screens, and other personally identifiable information. Manual frame-by-frame redaction is impractical beyond a short clip. Automated video redaction makes it feasible at scale.

PiiBlur processes video files up to 10 minutes long, detecting and redacting PII across every frame. Here is how it works and where it fits.

What PII appears in video files

Video captures everything a camera sees, continuously. The longer the recording, the more PII accumulates. Common categories:

• Faces and heads — the most frequent. Security cameras, dashcams, event recordings, and workplace footage all capture faces constantly.
• License plates — parking lots, dashcam recordings, street-level footage, and loading docks.
• Screens — office walkthroughs, training recordings, and facility tours often catch monitors displaying sensitive data.
• Name badges and ID cards — any environment where staff or visitors wear identification.
• Documents — whiteboards, posted notices, and papers on desks.

PiiBlur detects all 13 categories of visual PII, tracking each one across frames as subjects move through the scene.

How automatic video redaction works

PiiBlur's detection models analyze each frame, identify regions containing PII, and apply blur or pixelation throughout. The result is a new video file with all selected PII categories redacted and the rest of the footage intact.

You choose which PII categories to redact. A fleet dashcam operator might redact faces and license plates but leave street signs visible. A surveillance team might redact everything except the physical environment. Categories are configurable per job.

Processing limits

Video files can be up to 10 minutes long per job. For longer recordings, split them into segments before uploading. Most security and dashcam systems already export in segmented clips, so this aligns with standard workflows.

Two ways to redact PII from videos

Dashboard upload

The dashboard is the fastest path for ad hoc work. Upload your video, select PII categories, choose blur or pixelation, and submit. PiiBlur processes the video and notifies you when the download is ready.

This approach works well for:

• One-off redaction of a specific recording
• Teams without developer resources
• Evaluating PiiBlur's detection quality against your footage

REST API integration

For recurring workflows, the API eliminates manual uploads. Send a video file to the API, specify redaction settings, and receive the processed file back programmatically.

The API supports webhook notifications. Register a webhook URL and PiiBlur will POST to it when your video is ready — no polling required. This suits background processing pipelines where you submit a job and move on.

A typical API integration looks like this:

1. Your system captures or receives a video file.
2. It sends the file to PiiBlur's API with the desired PII categories and redaction style.
3. PiiBlur processes the video asynchronously.
4. Your webhook endpoint receives a notification with the download URL.
5. Your system retrieves the redacted file and stores or publishes it.

No manual intervention at any step.

Industries that rely on video redaction

Any organization that records footage containing people or vehicles has reason to redact it before sharing, archiving, or publishing.

Fleet and transportation. Dashcam footage from delivery vehicles, ride-share fleets, and freight trucks captures faces and plates throughout every trip. Companies redact before sharing with insurers, training teams, or legal reviewers. See how PiiBlur handles fleet dashcam footage.

Security and surveillance. Building security cameras, retail loss-prevention systems, and campus monitoring produce footage that often needs redaction before sharing with tenants, law enforcement, or legal counsel. Redacting bystander faces and unrelated PII protects individuals who are not the subject of a review. Learn more about surveillance redaction.

Real estate and property. Virtual tours, drone footage, and listing photos capture neighbors, passersby, and vehicles. Redacting before publication protects people who never consented to appear.

Media and journalism. News organizations, documentary producers, and content creators redact faces, plates, and other PII to protect sources, bystanders, and minors.

Video redaction pricing

PiiBlur's free tier includes 5 minutes of video per month — enough to test against your actual footage. Paid plans start at $49/month, with higher tiers offering more processing time and API access. Check pricing for details.

Video processing consumes more resources than image processing, so video minutes are metered separately from image counts. Each plan specifies its video allowance.
