8 Best AI Video Enhancers to Upscale Video Quality (2026 Review)

In an era where visual content is king, blurry or low-resolution videos can ruin precious memories or professional projects. Thanks to the rapid advancement of artificial intelligence, AI video enhancers have become the ultimate solution to breathe new life into old footage. Whether you need to fix motion blur, remove noise, or upscale 1080p to 4K, these tools use sophisticated neural networks to recreate missing pixels and deliver stunning clarity.

In this guide, we review the top 8 AI video enhancers available for Windows, Mac, and online, helping you choose the right one to transform your videos into cinematic masterpieces.

How We Test and Review

All desktop software is tested on an NVIDIA RTX 4080 (16GB VRAM) rig to measure real-world rendering speed and GPU efficiency.
We use a standardized 5-minute 1080p clip and time exactly how long it takes to upscale to 4K. This gives us a concrete "Speed Score" for every tool.
We test each AI model against four "nightmare" scenarios: grainy 480p family tapes, blurry handheld action shots, low-light night scenes, and heavily pixelated social media downloads.
