Part 1. How to add a beep sound to a video with Filmora

Filmora's powerful video editing menu includes easy tweaking on audio. You can censor any part of speech you want to exclude from your video with just these simple steps.

Step1 Create a new project and import the video to Filmora.

Part 2. How to add mosaic to video with Filmora

Whether you want to hide a passerby's face or your own, or even other types of objects, Wondershare Filmora is ready to take on the task. While its nifty face-off function automatically follows the movement of a marked face, the mosaic effect is the fast and perfect solution for a static object in the video.

Step1 After importing a video to Filmora, tap on the Effects tab and find the Mosaic filter from the gallery.

If the targetted object moves, you can set the automatic tracking before adding the mosaic filter by clicking on the Motion Tracking>Start Tracking located above the timeline. Before you place the filter, preview and adjust the tracking frame to ensure tight proof censor.
