Whether you're trying to upload a 4K video to Instagram or upscale an old 480p clip for a presentation, knowing how to change video resolution is essential. The wrong resolution can mean rejected uploads, choppy playback, or wasted storage space.

Blurry faces in videos are a persistent problem for content creators, archivists, and anyone restoring old footage. Low-resolution cameras, motion blur, poor lighting, and heavy compression all strip away the facial details that matter most.

Modern deep-learning models trained on millions of facial images can detect degraded faces, predict missing details, and reconstruct photorealistic clarity frame by frame. This guide walks through the causes of facial blur, how AI restoration works, and a step-by-step tutorial using UniFab Face Enhancer AI to unblur faces in video.
