Manual Mosaic: The Fastest Way to Blur a Still Face
So you’ve got a video with someone just chilling, not moving much. This is the easiest case. Here’s what I do:
- Head to the Effects menu in Filmora
- Search for Mosaic
- Drag the Mosaic effect onto your video track
- A blue square pops up—resize and move it over the face you want to hide
- Adjust the strength and style to your taste
Done. Preview the video, and you’ll see the face is now a pixelated blur. If the person’s on screen for a while, just stretch the effect to last as long as you need.

AI Motion Tracking: Censor Faces That Move
But what if the person’s walking, turning, or the camera’s moving? Manual just won’t cut it. That’s where Filmora’s AI tools come in. Here’s my workflow:
- Click the video clip you want to edit
- Go to AI Tools
- Scroll down and pick Motion Tracking
- Draw a rectangle around the face you want to censor
- Click Start Motion Tracking and let the AI do its thing
The AI tracks the face’s position as it moves. When it’s done, you’ll see a Link Element option—click it, then add the Mosaic effect. Resize the mosaic overlay so it fits the face, and you’re set. Play it back and watch the blur follow the face around, even if they’re moving.
Pro tip: Make sure your playhead is at the very start of the section you want to track. If you start halfway through, the effect only works for that part. Want to see more video editing tips? Here’s my guide for beginners on simple video editors.
Auto Face Detection: The Face Off Effect
If you have a bunch of people in the shot, or you just want to speed things up, there’s another tool: Face Off. Here’s how I use it:
- Go to Effects > search for Mosaic
- Find the Face Off effect (it’s free, no Pro version needed)
- Drag it onto your video
Face Off tries to detect every face in the video and applies a blur or funny mask. It’s not as precise as AI motion tracking, but it works for group shots or quick jobs. It tracks faces as they move, so you don’t have to do anything extra.
Quick Comparison Table
| Method | Best For | Tracks Movement | Manual Setup | Auto Detects Faces |
|---|---|---|---|---|
| Mosaic | Still faces | No | Yes | No |
| AI Motion Track | Moving faces | Yes | Yes | No |
| Face Off | Multiple faces, groups | Yes | No | Yes |
Common Mistakes and How to Avoid Them
- Forgetting to start at the beginning: If you add motion tracking in the middle, it won’t cover the whole clip.
- Overlay not sized right: Always double-check the mosaic covers the whole face, especially if the person moves.
- Effect not long enough: Stretch the effect so it covers the entire time the face is visible.
