Use glass blur to blur out something in a video, like a name, a number, or a face, by covering it with a blurred layer. It softens whatever shows through the shape without touching the layer beneath. Unlike the standard [**Blur**](https://help.descript.com/hc/en-us/articles/10327647505549) effect, which blurs its own layer, glass blur is made to sit over a transparent layer and blur what's underneath. **Glass blur is not secure redaction**\ The Glass blur effect is visual only and should not be used to obscure sensitive or private information. If you need to securely hide content, use a solid shape with 100% opacity instead. ## How to add Glass Blur 1. Add a layer from the **Elements** panel in the right sidebar. 2. With the element selected in [the scene editor](/visuals/scene-editor-overview), click **Effects** in the hover toolbar. 3. Choose **Glass blur** from the effect list, then toggle it on. Adjust the **amount** of blur via the slider in the options menu
