Video restoration is the process of recovering watchable quality from damaged or degraded footage by removing noise, rebuilding sharpness, correcting faded color, stabilizing motion, and keeping detail consistent between frames.

This guide breaks down how modern AI restoration actually works, what it can and cannot fix, which tools lead the field, and how to pick between doing it yourself and paying a studio. It leans on hands-on testing with VHS transfers, compressed social clips, and 8mm film scans across a Windows RTX 4060 rig and an Apple M2 Pro laptop.
