Auto-Blur Bystander Faces in Videos Locally with Open-Source Deface
Shooting street vlogs or store tours with lots of passersby? Run open-source Deface locally to track and blur every bystander face across frames while keeping original audio.
CORE TOOLS
Deface (Open Source), FFmpeg
BEST FOR
Vloggers, store reviewers, school/corporate media teams, video editors
REQUIREMENTS
Python and FFmpeg (runs smoothly on standard laptop CPUs)
✦ WHY THIS WORKFLOW
Keyframing blur masks by hand for dozens of moving passersby takes hours. Lightweight local face detection processes an entire clip in minutes.
Write a batch script (both Windows PowerShell and macOS Bash) using open-source `deface` and `FFmpeg` to anonymize all `.mp4` files in a folder:
1) Loop through all `.mp4` files;
2) Enable `--keep-audio`, set detection threshold `--thresh 0.15` and mask scale `1.3`;
3) Save all processed videos into `./blurred_output/`.
