10 Best AI Tools For Upscaling Videos to 4K in 2025 (No 4K Camera Required)

Do you know you don’t need high-res cameras to get high-res videos? Artificial intelligence now makes this possible. AI lets you enjoy 4K videos without needing a high-end camera. How? By using an AI 4K upscaler to transform your old or lower-quality videos into modern 4K resolution!

Part 1. How AI Video Upscalers Work

The game changer was the discovery that AI and neural networks trained on millions of videos could pave the way for video enhancement and upscaling. Today, you can upscale 1080p to 4K, or even from a poorer original resolution, into 4K or higher.

An AI 4K upscaler reconstructs your video by analyzing blurry frames, recognizing patterns such as edges and textures, and then regenerating dull pixels to create a sharper, higher-resolution video from your original video.

So, before pulling out your wallet to purchase that expensive high-end camera, try out the innovative software solutions we'll be reviewing below. These tools are specifically designed to upscale video to 4K.
