# Masks

### **1. Sensitive Content Visibility in Velo Generation**

You can hide sensitive information using the **Masks** feature. This
tool allows you to cover or blur specific areas of your screen such as
passwords, personal emails, or private dashboard data ensuring that your
viewers only see the information you want to share.

### **2. Applying Multiple Masks to a Single Video**

The Velo timeline includes a dedicated **Masks** track where you can
manage multiple entries. Similar to how you can have multiple **Zoom**
blocks at different points in your video, you can add multiple mask
segments to cover different sensitive areas throughout your walkthrough.
