Part 2: How to Enhance Faces in Videos with UniConverter 18 for Mac

Step 1 Launch Video Enhancer on Mac.

Open Wondershare UniConverter 18 on your Mac and select Video Enhancer from the Home screen. This opens the dedicated workspace for improving video quality with AI.

Step 2 Select Face Enhancement and add your video.

In the Video Enhancer interface, locate Face Enhancement under Enhancement & Upscaling. Select this feature to improve blurry or low-quality faces in your video. Then click Add Files to import a supported portrait video from your Mac.

Step 3 Adjust the output resolution and preview the enhancement.

After importing your video, choose the available Output Resolution under Face Enhancement. Options include Original, 2X, 4X, 1080P, and 2K. Select the resolution that best suits your output requirements.

Face Enhancement uses generative AI to help restore facial details and improve the appearance of blurred or partially obscured faces. Click Preview (3 s) to generate a short enhanced preview before processing the full video.

Step 4 Review the original and enhanced video.

Once the preview is ready, compare the Original and Result views to evaluate the improvement in facial clarity. Pay attention to fine details around the eyes, hair, skin, and facial contours. Play the preview to check whether facial details remain consistent across frames.

If the results meet your expectations, click Exit Preview to return to the enhancement workspace.

Note: Enhancement quality depends on the original footage. Videos with severe blur, extensive facial occlusion, or rapid movement may produce varying results.

Step 5 Enhance and export your video.

Choose your preferred output folder under Save to, then click Enhance All & Export to process the video. UniConverter 18 for Mac creates an enhancement task and displays a notification when the export process begins. Click OK to dismiss the notification.
