Apply AI Face Mosaic

Step 1. Open AI Face Mosaic Tool

Start Wondershare Filmora on your Mac and access the main dashboard. Enter the Toolbox section and select the AI Face Mosaic feature from the available AI tools. After that, upload the video or image file you want to process into the editing workspace.

Step 2. Let AI Detect Faces

After importing the media, Filmora will automatically begin detecting faces within the clip. Wait for the scanning process to finish, then choose a mosaic style from the settings panel to apply the blur effect to detected faces.

Step 3. Enable the Reverse Effect

Turn on the Reverse option from the right-side panel if you want the mosaic effect applied to the background instead of the faces. This setting helps create unique visual or privacy-focused results.

Adjust AI Face Mosaic

Step 1. Manage Face Selection

Select the detected faces that should remain blurred or remove selection from faces you want to keep visible during playback.

Step 2. Refine Mosaic Appearance

Use the available sliders to modify Strength, Feather, and Opacity settings. These adjustments help control the softness and visibility of the mosaic effect for a cleaner final output.
