How Do You Blur Objects in Filmora

Most of the time, people want to blur backgrounds to help focus the viewer’s eye on the subject of choice, but sometimes you only want to blur out an object.

This could be the face of a person you didn’t have permission to film, or it could be an object or inappropriate text that doesn’t fit with the theme of your video.

Whatever the reason, it’s great to have the option to blur faces and objects so that you don’t have to scrap your precious clips.

To blur out an object or blur faces, you will have to activate the motion tracking feature.

Select the clip in the timeline so that it’s active.

To activate the tracking feature, click on the motion tracking icon above the timeline (the square with a plus sign that sits to the left of the crop icon).

Once clicked, the tracker, a square with a plus symbol inside, will appear on the video preview screen.

Drag the tracker over the face or object and increase or decrease the size of the area to be tracked by moving the bounding line of the tracker.

Then click the Start Tracking button in the panel to the left of the video preview.

Once clicked, the video will play, and the tracking box will remain positioned over the face or object even when it moves position.

If you are content that the tracker is covering the face or object for the duration of the clip, you can add the blur effect.

Click on the drop-down menu below tracking and select Add a Mosaic.

Now you will be presented with the option to select “Type”, “Blur Amount” and “Opacity”. Choose your settings, and preview the result.

This is a useful video editor function to remember for when you want to add motion blur effects, as the tracker will follow the object.

And that’s how you blur just a section of your video – a useful editing trick to know.
