5-step video de-identification — detect faces automatically, then fine-tune masks before export

1

Open your video

Choose an MP4, MOV, AVI, or WebM file. Opening a video does not upload it to a server; the file stays on your device and is processed locally in the browser.

2

Analyze faces automatically

AI detects and tracks faces throughout the video. Timeline thumbnails are prepared during analysis so you can review the result without decoding the video again.

3

Select faces to mask

Choose which detected faces should be de-identified. You can keep specific faces visible, or de-identify only the ones you select.

4

Edit masks on the timeline

Review the result frame by frame. Move or resize mask boxes, remove false positives, add manual masks, and preview the actual de-identification effect before export. Sign-in is required to edit masks.

5

Export and download

VideoMasker encodes the final video with your selected faces and manual edits applied. Where supported, frame-accurate timing and original audio are preserved.

Mask Editing

VideoMasker combines AI-generated mask tracks with manual keyframed tracks, then applies all corrections during final encoding.
