AI Upscaling Video: Upscale Videos to 4K, Even 8K With AI in Simple Way

"Is there any AI upscaling tool for videos? I’m working on an amateur project, and for part of my project, I’ll be using some old, really, really low-res film. I’ve used some free online tools to upscale low-res photos before, to great success. How about AI upscaling video?"

How to upscale the old and low-res video or film? To solve such a problem, we discuss the following solutions of AI upscaling videos in this article.

AI Upscaling Video

Part 1: How Does AI Upscale A Movie/Video?

This handy development in TV picture processing is able to take the content of a lower resolution than your TV’s own panel and optimize it to look better, sharper, and more detailed. It may sound a lot like regular old upscaling – the ‘AI’ part just means the upscaling happens with a greater awareness of context. That’s because Al upscaling involves creating new pixels of image information to add detail where there wasn’t any before, filling in the gaps to recreate a higher-resolution image, all the while using machine learning to improve the result.

Artificial Intelligence uses a network of simulated neurons (neural network) to augment the ability of a computer to perform tasks that rigid classical programming cannot easily achieve such as perception, interpretation, and prediction.

In the case of upscaling images or video (sometimes referred to as super-resolution), the algorithm is essentially tasked with creating extra pixel data to fill in the missing gaps between the known pixel values. Classical approaches to upscaling is called interpolation, which often simply fills in the missing pixels with color values that split the difference between their nearest neighboring pixels.

Of course, a human would be capable of perceiving the objects in the image, and having prior knowledge of the characteristics of these objects, be capable of predicting what the missing pixel values could be.

This is where artificial intelligence comes into play. Having been trained on a large volume of image sets containing high and low-resolution pairs, it becomes capable of generalizing the process of upscaling similar images. And the following tools are all embedded with AI.

Part 2: 7 Best AI Video Upscaler to Upscale Videos to 4K, 8K
