How to Blur One Person in a Group Video

To blur one person in a group, use Select faces in Unseen. After detection, click Clear, then mark every face entry belonging to that person Hide. Leave the other entries Keep, choose Continue processing, and check the finished video.

The easy mistake is to select only one thumbnail even though the same person appears in several entries. Look through the whole face list before rendering.

Start with a person you can recognize in the source

Watch the original once and note how the person appears: clothing, position, close-up versus wide shot, glasses on or off, and any camera changes. Those details help you recognize their face thumbnails.

For a panel discussion, you might be hiding the guest seated second from the left. In a sports clip, the subject may move across the whole frame. The first is much easier to verify than the second, even if both have only four people.

Choose Blur on the import screen and click Select faces, not Blur all.

Read Hide and Keep literally

Hide applies the effect. Keep leaves the face visible. The button labels describe the output, not whether a person is included in the video.

Using Clear gives you an explicit starting point with nobody selected for treatment. Then click the target person's entries and confirm the badges. If everyone else should be hidden instead, use the inverse-selection guide.

You can use the three-dot menu to give that person Pixelate or Black bar instead of the default Blur. Check for an existing per-face override if changing the default later seems to have no effect.

Check where people cross or disappear

The face list is a selection aid, not a verified identity record. Someone can be split into several tracks, and tracking can become confused where two people overlap.

Pay attention when the target walks behind another person, leaves the frame, or returns after a cut. Check whether the mask comes back on the correct face. Also make sure another person's face has not become hidden in their place.

Local Maximum detection can be worth trying if appearances are brief. It does not guarantee correct association through an obstruction.

If the person is missing from the face list

Do not select someone who merely looks similar and hope the effect will transfer. Try a clearer source or a more thorough local detection preset. If the person still cannot be selected reliably, open Review & fix faces, draw a box on them and track it through the video (step by step), or crop or trim that section in your video editor.

When the target occupies only a small part of a large group shot, changing the framing may produce a better video as well as an easier privacy edit.

Use Export video to save the result, then watch that file from start to finish. The target should stay hidden without the rest of the group unexpectedly disappearing behind masks.
