UniConverter AI Video Blur provides two modes: AI Face Blur mode automatically detects faces, while Object Tracking Blur mode follows an object you select manually.
Open UniConverter AI Video Blur and choose Object Tracking Blur mode. Draw a box around the license plate, logo, screen, label, badge, or other target. AI follows the selection as it moves, so the blur stays aligned without frame-by-frame keyframing. Choose a Blur Style, preview the coverage, and export.
If the target is a person, choose AI Face Blur mode instead. UniConverter scans the video, generates face thumbnails, and lets you select one, multiple, or all detected people to conceal. See the dedicated guide to blur a face in video.
Motion tracking blur follows and conceals a selected target. It is different from a cinematic motion blur effect, which adds visual streaks to movement.
Hide only the sensitive detail while leaving the rest of the frame clear. Object Tracking Blur works with moving or stationary items that you select manually. For a fixed region or several separate areas, see how to blur part of a video.
Select the plate and keep the blur attached while a car, motorcycle, or camera moves.
Conceal a selected brand mark, platform graphic, or source identifier as it changes position.
Hide moving windows, account names, emails, order details, API keys, or dashboard data.
Blur contracts, shipping labels, forms, presentation text, or other readable details.
Protect employee IDs, building numbers, street signs, door labels, and location clues.
Hide unreleased designs, product labels, prices, tattoos, or other identifying details.
Adding blur to one frame is easy. Keeping it over the same detail while the object or camera moves is the real challenge. UniConverter combines a simple selection with AI tracking, so the blur follows the target through the clip.
Draw a box around the target in Object Tracking Blur mode. AI analyzes its movement and keeps the blur aligned through the video, so you do not have to reposition a mask whenever the target changes position.
Use Blur or Mosaic for familiar privacy masking, or choose Particle, Smear, Pastel, Sketch, Horizontal, Cross, Ink, or Paint for a more stylized result. Then fine-tune how the effect covers the target.
Preview the result to confirm that the selected detail remains covered from beginning to end. Pay extra attention when the target moves quickly, changes size, passes behind something, leaves the frame, or appears after a shot change.
Process the original video in UniConverter instead of uploading the unblurred file to an unfamiliar browser tool. You can also add multiple videos and continue converting, compressing, trimming, editing, or enhancing them in the same app.
Use the same three-step workflow for a moving license plate, logo, phone screen, label, badge, sign, or another target. Start from a frame where the object is clearly visible for a cleaner selection.
Open AI Video Blur and add one or multiple videos. Select the clip containing the object you want to conceal.
Choose Object Tracking Blur mode, draw a box around the target, and let AI follow it. Then choose a Blur Style and adjust Strength, Feather, and Opacity.
Watch the blur across the full clip, check fast movement and obstructions, make any needed adjustments, choose a save location, and export.
A clear starting selection helps AI follow the right detail, while a final preview helps you catch the moments when coverage is most likely to slip.
Use object tracking whenever a private, distracting, or unreleased detail moves within the frame, changes size, or shifts because the camera moves.
Blur license plates, road signs, addresses, or identifying vehicle details before sharing accident, travel, cycling, or street footage.
Use a static blur when the detail never changes position. Use manual keyframes when a difficult shot needs detailed correction. Choose AI object tracking when you want the blur to follow a selected target with less setup.
| Workflow Need | UniConverter Object Tracking Blur | Manual Mask and Keyframes | Static Blur Overlay |
|---|---|---|---|
| Keep blur on a moving target | AI tracks the selected object | Reposition or correct the mask over time | Does not follow movement |
| Initial setup | Draw a box around the target | Create a mask and timeline keyframes | Place one fixed blur area |
| Best use | Moving plates, logos, screens, labels, badges, and other details | Complex shots that require detailed manual intervention | Stationary details in locked-off footage |
| Effect controls | 10 Blur Styles plus Strength, Feather, and Opacity | Depends on the editor and applied effect | Usually limited to the overlay settings |
| Frame-by-frame keyframing | Not required for normal tracked movement | Commonly required for position or shape corrections | Not used, but the blur remains fixed |
| Sensitive source footage | Processed in a local desktop workflow | Local when using a desktop editor | Depends on the chosen desktop or online tool |
| Multiple source videos | Batch video workflow | Usually set up by project or sequence | Depends on the tool |
Best fit: Choose UniConverter when the target moves and you want a faster alternative to building a mask and adjusting keyframes across the timeline. Preview the result before publishing, especially after fast motion, obstruction, re-entry, or a shot change.
Protecting one detail does not have to become a separate upload and download task. Complete the object blur, then continue the rest of your video workflow in UniConverter.
Work with MP4, MOV, AVI, MKV, M4V, WMV, FLV, MTS, TS, 3GP, and other commonly used formats supported by the feature.
Trim or prepare the source, apply object tracking blur, preview the full clip, and continue converting, compressing, editing, or enhancing it with the broader video blur editor workflow.
Direct answers about selecting, tracking, blurring, checking, and exporting moving-object footage.
Open UniConverter AI Video Blur, choose Object Tracking Blur mode, draw a box around the object, select a Blur Style, and let AI track it. Preview the coverage, adjust Strength, Feather, or Opacity if needed, then export.
Select the object on a frame where it is clearly visible and use motion tracking blur. The tracker analyzes the target's movement and keeps the concealed region aligned as the object moves through the clip.
Motion tracking blur combines a selected region with tracking data so the blur follows a person or object over time. It is different from cinematic motion blur, which creates streaking to make movement look smoother or faster.
UniConverter automatically scans for faces in AI Face Blur mode. For license plates, logos, screens, documents, labels, and other non-face targets, you select the object first and AI tracks that selection afterward.
No. For normal tracked movement, AI follows the selected target without requiring you to create and reposition keyframes throughout the clip. You should still preview the result before export.
Yes. Object Tracking Blur can cover moving or stationary visible details. Tracking is especially useful when the camera moves because the selected detail can change position within the frame even if the real-world object does not move.
Inspect fast movement, camera shake, low contrast, obstruction, exits and re-entry, and shot changes. Start from a clearer frame, include the whole target in the selection, reselect it when needed, and preview again before export.
You can choose Particle, Smear, Pastel, Sketch, Horizontal, Blur, Cross, Ink, Mosaic, or Paint, then adjust Strength, Feather, and Opacity. Sticker is planned for the V18 release.
No. UniConverter AI Video Blur runs in the Windows or macOS desktop application, so the unblurred source can remain in a local workflow instead of being uploaded to an unfamiliar online blur site.
Yes. Add multiple videos, switch between the clips to review their targets and settings, then process and export them in the same batch workflow.
Select a plate, logo, screen, label, or other detail once. Let AI follow it through the clip, customize the coverage, preview the result, and export from your desktop.
