Blur Face Video - TrackBlur

Blur Video: faces, objects - the ultimate offline video editor to anonymize video app content with face video blur, object tracking, and custom areas.

TrackBlur uses on-device AI for smart video masking and censor video face needs, so privacy protection moves with your subject even when the camera does. Its integrated motion tracker ensures your edits stay perfectly in place. Put mask on the area you want and hide it.

How it works

Pick a video. Choose what to blur. Done.

This automatic video censor scans your video and builds a detection timeline. You stay in full control of your video mask editor before a single frame is rendered.

Instant Auto-Blur: Skip the Editor

Select "All Faces" to hide identity video clips instantly. Skip the editor and export in seconds for the fastest auto face blur and privacy protection available.

Pro Timeline Editor

Take command with a full-featured video editor interface designed for precision.

- Multi-track editing - manage separate tracks for faces, objects, manual regions, and text overlays simultaneously.

- Frame-by-frame control - scrub through your video with high precision to ensure every sensitive detail is covered.

- Video trimming - cut and trim your clips directly within the app before applying effects.

- Timeline scaling - zoom in for detailed keyframing or zoom out for a full project overview.

Four tracking modes

Face blur - An ai video blur mode that detects every face. Use Selective mode to choose specific people, or All Faces to anonymize everyone automatically.

Objects blur - Pro object tracking blur to instantly track cars, pets, and more. It tracks various object classes across every frame so you don't have to edit manually.

Manual blur - A precision motion tracking tool to blur logos, watermarks, usernames, or any custom region. Draw, resize, and position custom blur regions that follow the subjects as they move — automatically, no keyframes needed. Perfect for video redaction and removing branded content.

Animated regions - A powerful keyframe video editor feature. Add an animated video blur and place keyframes on the timeline to animate the blur path exactly where you need it.

Text Objects

Add text overlays that can be keyframed and animated on the timeline. Use text for censor bar overlays or labels that move perfectly with your subjects.

Four blur effects

Blur - Gaussian video face blur with adjustable intensity.

Pixelate - A classic mosaic video or pixelate moving objects effect.

Cover - Solid color overlay for a clean black bar or custom censor bar look, fully customizable.

Highlight - Spotlight effect to draw attention instead of hiding.

Audio censoring

Mute audio, add a beep tone, or lower the volume on any range of the timeline. Hide voices, names, or sensitive sounds with a built-in censor beep — perfect for street interviews, podcasts, and reaction videos. Combine audio bleep with face blur to fully anonymize a clip in one pass.
