Simple and Fast: How to Upscale Video in Waifu2x

Everyone expects videos to look crisp and clear on any screen, whether it’s a smartphone or a 4K television. Low-resolution videos can appear blurry, pixelated, and outdated, which reduces their impact. This is why video upscaling has become increasingly important. By using an advanced video upscaler, creators can enhance video quality and transform ordinary footage into something closer to cinematic standards.

Among the available tools, Waifu2x is recognized for its free, AI-based approach to image and video scaling, particularly popular among anime and cartoon enthusiasts. This article will guide you on how to upscale a video with Waifu2x. Furtherly, there is an easier alternative, VidHex, offering simpler workflows and higher-quality output.

Part 1. What Is Video Upscaling

Video upscaling is the process of increasing a video’s resolution, for example, from 720p to 1080p or from Full HD to 4K&8Kresolution. Traditional scaling methods simply stretch the image, which often leads to visible blur or blocky pixels.

AI-based video upscaler, on the other hand, uses machine learning models to predict missing details and intelligently enhance textures, edges, and colors. This makes the final video look sharper and more natural, even when displayed on a large 4K screen.

Part 2. How to Choose a Video Upscaler

When deciding how to upscale video, you’d better consider those factors:

Output Quality – Different video upscalers are designed for different uses. Pick a professional one if you want a high-quality result.

Ease of Use – If you are a beginner, ensure the interface is friendly enough to start, and no coding knowledge is required.

Speed – The upscaling time depends on the software and how long the original video is. So, choose an efficient tool and import a short video if pursuing fast processing.

Hardware Requirements – Most AI tools run smoothly on average computers, while some demand powerful GPUs. Please upgrade your device before downloading them.

Supported Formats – A good video upscaler should support MP4, MOV, AVI, MKV, and other common formats.

By comparing these factors, you will make a proper choice on which tool suits you best. Most people tend to use free video upscalers, among which Waifu2x is a popular one. And this article is going to show you how to upscale video in Waifu2x.
