TrackBlur uses on-device AI to detect faces automatically — plus custom blur regions that follow anything you draw around. Pixelate, mosaic or cover. Your clips never leave your phone.
Pick a video and choose your engine — detect faces automatically, track custom moving targets, or keyframe manual paths. These three timeline engines power all of TrackBlur’s tools, from privacy blurs to moving labels, stickers, and depth overlays.
On-device AI finds and tracks every face automatically. One-tap auto-blur all faces, or selectively pick specific people to blur while keeping yourself sharp.
Lock custom blurs, text labels, or photo stickers onto moving targets. The engine tracks the subject automatically through the frame — no manual keyframes needed.
Add keyframes along the timeline to animate blurs, text, or shapes with frame-level precision. Smoothly transition opacity, scale, and blur intensity.
Every clip below was rendered fully on-device. No upload, no server watermark — just the result.
Automatically blur every detected face in the full video. One-tap auto face blur — no manual selection needed.
How-to guide →Select only the face tracks you want to blur. Keep yourself sharp, blur everyone else in the clip.
How-to guide →Motion tracking blur keeps your custom region attached to its target as it moves through the frame — no keyframes needed.
How-to guide →Draw a custom video blur region, then add keyframes along the timeline — the region smoothly animates between them.
How-to guide →Draw a text box on the video, customize font, color and outline — then keyframe it to animate with the scene.
How-to guide →Attach a text label to a moving person, logo or object. The label follows automatically — no keyframing needed.
How-to guide →Add arrows, markers, shapes, or photos on top of your video. Track stickers to follow moving targets.
How-to guide →Create a depth effect by placing text, stickers or photos behind people or foreground subjects.
How-to guide →Mute a sensitive range, replace speech with a censor beep, or lower volume while keeping the rest of the original audio intact.
How-to guide →Timeline editing, auto face blur, motion tracking, custom regions and pixelate / mosaic effects — all on-device.
