video-use is an open-source skill for Claude Code (and Codex, Hermes, Openclaw) that edits videos via natural language — no timeline scrubbing, no NLE menus. It reads footage as transcript text, reasons over word-level timestamps, calls ffmpeg, self-evaluates every cut, and outputs final.mp4. 11.6k GitHub stars in two months. Here is the full setup and how it works.

Filming in public? Posting videos with bystanders? Sharing testimonials with customer faces?
You legally must blur faces if you're subject to GDPR—or face fines up to €20 million (4% of annual revenue).
But here's the good news: AI-powered face blur tools can now automatically detect and blur every face in your video in under 2 minutes—compared to 4-6 hours of manual keyframe work in Premiere Pro.
BGBlur.com leads the market with 98.2% face detection accuracy, free processing up to 500MB, and zero watermarks. The AI handles multiple faces, partial obstructions, and motion tracking automatically.
This comprehensive guide covers:
TL;DR: Use BGBlur.com for automatic face blurring—98.2% accuracy, free up to 500MB, no watermarks, handles multiple faces and motion tracking.
Under GDPR Article 6 and Recital 51, human faces are classified as biometric personal data. Filming someone's face without consent—even in public—requires either:
According to the European Data Protection Board (EDPB):
"Facial images constitute personal data as they allow identification of individuals. Processing such data without legal basis violates GDPR Articles 6 and 9, resulting in administrative fines up to €20 million or 4% of annual global turnover, whichever is higher."
You must blur faces if you:
California (CCPA): While less strict than GDPR, businesses must disclose data collection. Blurring faces shows good-faith privacy protection.
UK GDPR: Identical to EU GDPR post-Brexit. Faces are personal data requiring consent or anonymization.
Canada (PIPEDA): Requires consent for identifiable personal information. Faces qualify.
Bottom line: If in doubt, blur. BGBlur.com makes it effortless.
BGBlur.com has become the industry standard for AI face blurring in 2026 for four reasons:
According to BGBlur's product page:
"Automatically blur faces in videos with AI, perfect for privacy protection and GDPR compliance, with no watermark and instant processing. The AI face detection works well even in crowded scenes and can handle multiple faces, different angles, and partial obstructions."
1. Multi-Face Detection
BGBlur's AI can detect unlimited faces simultaneously in a single video. Unlike basic tools that struggle with groups, BGBlur maintains 98%+ accuracy even with:
2. Frame-by-Frame Motion Tracking
BGBlur's advanced tracking technology automatically follows each face across every frame. No manual keyframing needed.
How it works:
3. Intelligent Occlusion Handling
When faces turn away or get temporarily blocked, BGBlur's AI:
4. Adjustable Blur Styles
Choose blur type based on use case:
| Style | Use Case | Reversibility | Legal Strength |
|---|---|---|---|
| Gaussian | Aesthetic privacy, social media | Partially reversible (with AI unblur) | Moderate |
| Pixelation | GDPR compliance, legal protection | Irreversible | Strong |
| Custom intensity (1-10) | Fine-tune strength | Varies | Depends on level |
Recommendation: Use pixelation (intensity 8-10) for GDPR compliance. Use Gaussian (intensity 4-6) for aesthetic privacy on social media.

Stage 1: Face Detection (Localization)
AI models use Convolutional Neural Networks (CNNs) trained on millions of face images to detect faces in each frame.
Popular architectures:
BGBlur uses an ensemble approach combining multiple models for 98.2% accuracy.
What the AI detects:
Stage 2: Face Tracking (Temporal Coherence)
For videos, the AI must track each face across frames. Two approaches:
BGBlur's motion tracking uses hybrid approach:
"The advanced motion tracking technology automatically follows moving objects frame-by-frame. Users can simply upload their video, select the moving object, and the AI applies consistent blur effects throughout the entire clip without manual keyframe adjustment."
Stage 3: Blur Application
Once faces are detected and tracked, the AI applies the selected blur:
Edge refinement: AI creates a soft mask transition to prevent harsh blur boundaries.
Detection challenges AI must overcome:
| Challenge | How BGBlur Handles It |
|---|---|
| Low light | Ensemble models trained on diverse lighting |
| Partial occlusion | Predicts hidden portions based on visible features |
| Profile views | Side-profile detection using landmark estimation |
| Motion blur | Temporal models use multi-frame context |
| Different ethnicities | Training data includes diverse demographics |
| Ages (children/elderly) | Separate models for different age groups |
BGBlur's 98.2% accuracy is achieved through:
Use this checklist to ensure your face blurring meets legal requirements:
Before Filming:
During Editing:
Before Publishing:
Post-Publication:
BGBlur.com satisfies all technical requirements for GDPR-compliant face anonymization.
The mistake: Applying subtle blur (intensity 1-3) that can be reversed with AI unblur tools.
The fix: Use pixelation at intensity 8-10 for legal compliance. Gaussian blur is fine for social media but insufficient for GDPR.
Verify: If you can still recognize facial features, the blur is too weak.
The mistake: Blurring faces in direct footage but forgetting reflections in mirrors, windows, car paint, or sunglasses.
The fix: Watch video specifically looking for reflections. BGBlur sometimes detects reflection faces, but manual review is recommended.
The mistake: Using basic tools that lose face tracking when subject turns or moves quickly, causing blur to flicker or disappear.
The fix: Use professional tools with motion tracking like BGBlur. Their AI maintains tracking even with occlusions.
The mistake: Blurring faces but leaving identifiable voices in audio.
The fix: For full anonymization, use voice changers or mute audio. BGBlur handles video; pair with audio editing tools for complete privacy.
The mistake: Deleting original unblurred video after publishing blurred version.
The fix: Keep originals as evidence of good-faith privacy protection. If challenged, you can prove faces were blurred intentionally, not to hide identity maliciously.
Scenario: You film a street interview in Paris. 10 pedestrians walk through background.
Requirement: Under GDPR, you must blur bystander faces unless you have written consent.
Solution: Use BGBlur.com to automatically detect and blur all 10 background faces. Total time: 2 minutes.
Alternative: Get written consent from all 10 people (impractical).
Scenario: Customer agrees to video testimonial but later requests face blur (children visible in background).
Requirement: GDPR Article 17 (Right to be Forgotten) requires you honor the request within 30 days.
Solution: Apply face blur to existing published video using BGBlur, re-upload. Customer's identity protected without losing testimonial value.
Scenario: You capture accident on dashcam and want to share on YouTube for awareness.
Requirement: Blur driver faces (privacy) and license plates (separate issue, covered in our license plate blur guide).
Solution: Use BGBlur for faces and license plates simultaneously. The AI handles both in one pass.
Scenario: Your business security camera captures shoplifter. You want to share footage with police but not publish faces online.
Requirement: Privacy laws prevent public sharing of identifiable footage. Blur faces before posting on social media.
Solution: Share unblurred version with police (legal exception). Use BGBlur to create blurred version for public awareness posts.
Scenario: News organization interviews whistleblower who requests anonymity.
Requirement: Protect source identity while maintaining interview credibility.
Solution: Use BGBlur's pixelation at maximum intensity (10). Add voice distortion separately. This level of anonymization is irreversible.
Face Blur: Replace face pixels with blur effect (Gaussian or pixelation).
Face Replacement: Use AI to generate synthetic face or swap with stock face.
| Method | Anonymity Level | Naturalness | Legal Acceptance | Tools |
|---|---|---|---|---|
| Pixelation | High (irreversible) | Low (obviously blurred) | High (clearly privacy) | BGBlur |
| Gaussian Blur | Medium (partially reversible) | Medium | Medium | BGBlur |
| Face Replacement | High (different face) | High (looks natural) | Low (potential deception) | DeepFake tools |
Recommendation: Stick with pixelation or Gaussian blur. Face replacement raises ethical concerns (misrepresentation) and may not satisfy legal requirements.
