How AI Video Blur Protects Privacy Without Keyframing

VideoBGBlur combines automatic subject segmentation and SAM3 text-prompted video tracking to detect faces, vehicle license plates, laptop/phone screens, backgrounds, or custom targets across motion frames. Once the tracking mask is generated, you can switch between Gaussian and Box blur or fine-tune blur intensity, mask expansion, and edge feathering at zero additional AI credit cost.

Input: MP4 / MOV / WebM (≤200 MB, ≤60s, ≤1080p, ≤30 fps) · Output: Composed H.264 MP4 with Audio · Auto-Refund on 0 Targets

02 / WHY CHOOSE THIS TOOL · CORE CAPABILITIES

Verified VideoBGBlur Capabilities

5 Target Modes

Faces, License Plates, Screens, Background & Custom Prompts

Use one-click presets for common privacy targets (`faces`, `license_plates`, `screens`, `background`) or type custom Keep/Add/Exclude prompts to blur badges, house numbers, or documents.

0-Credit Re-Renders

Adjust Blur Strength, Expansion & Feathering for Free

Your blur tracking mask is cached for 7 days. Change between Gaussian and Box blur or tweak pixel expansion and feathering as many times as you like without spending extra AI credits.

Auto-Refund Protection

100% Automatic Credit Refund When Zero Targets Are Found

If the AI scans your clip and detects no matching faces, license plates, or prompted targets, the job returns a target-not-found status and automatically refunds your reserved credits.

Predictable Pricing

Upfront Credit Quote & ~3-Second Preview Mode

Single-target blur and background blur cost 1 credit per billed second (2 credits/sec when combining multiple prompt rules). Test any clip first with a 3-credit preview.

03 / HOW TO USE · THREE-STEP WORKFLOW

How to Blur Faces, License Plates or Screens in 3 Steps

No manual timeline keyframing required. Upload your clip, pick a target mode, and export a privacy-compliant MP4.

STEP 01

Upload MP4, MOV, or WebM Video

Select a video up to 200 MB, 60 seconds, 1080p resolution, and 30 fps. Container metadata and frame rate are verified before any credits are reserved.

STEP 02

Select Blur Target & Run ~3s Preview or Full Clip

Choose Faces, License Plates, Screens, Background Blur, or Custom Prompt. Run a ~3-second preview for 3 credits or process the full video at 1 credit/second.

STEP 03

Fine-Tune Intensity & Export H.264 MP4

Reuse the generated blur mask for free to adjust Gaussian/Box filter strength, mask expansion (px), and edge feathering (px), then download your composed MP4 with original audio.
