Selective Face Blurring vs Blur-All: A Risk-Based Decision Guide

Use Blur all when nobody needs to remain recognizable. Use Select faces when the video benefits from keeping particular people visible or treating people differently.

The decision is best made per shot. A host introduction and a crowd cutaway in the same project can use different approaches.

Blur-all removes a selection task

For a market walkthrough or a wide audience shot, there may be no reason to preserve any face. Blur-all applies the chosen effect to detected faces without asking you to make individual face choices.

This saves time and avoids forgetting to select an incidental person. It does not guarantee every face was detected.

You still need to inspect small faces, profiles, reflections, and new arrivals at the frame edges.

Selective blur preserves useful expression

A presenter teaching an exercise or a guest giving an approved interview may need to remain visible. Selective treatment keeps that expression while hiding bystanders.

In Unseen, Hide applies the treatment and Keep leaves the face visible. Use Select all then reveal the presenter, or Clear then hide a particular person.

Check for multiple entries belonging to one person. The face list does not establish that every appearance was grouped correctly.

Compare two common scenes

One host against a busy background: Selective treatment is useful because the host's face carries the communication. Review crossings and reflections of the host carefully.

A two-second audience reaction shot: Blur-all may be simpler if no individual reaction is essential. If the effect overwhelms the image, choose a different shot rather than spending time on dozens of visibility decisions.

The right choice depends on the edit's purpose, not only the number of faces.

Selective treatment adds association risk

If two people cross and tracking becomes confused, the mask may move onto the wrong person. In blur-all, that identity distinction matters less when both faces receive the same effect, although coverage can still fail.

For difficult selective footage, test a short section. More frequent local detection may help some appearances but does not prove correct association.

If the scene cannot be handled reliably, shorten it, reframe it, or correct the boxes yourself in Review & fix faces.

Change methods without changing the purpose

Blur, Pixelate, Black bar, and Emoji are effect choices. Blur-all versus Select faces is a selection choice. Do not confuse the two.

Per-face method overrides let you give people different treatments within selective processing. Check those overrides if changing the default produces an unexpected mix.

Start with the one-person tutorial or keep everyone except the host hidden once you know which selection pattern the shot needs.
