Blurry to Brilliant: How to Upscale Video to Stunning Results

In today’s digital world, high-quality videos are more important than ever, whether for professional use, like filmmaking and content creation, or for preserving precious old memories. However, we inevitably come across blurry, pixelated, or low-quality videos due to unprofessional recording devices or quality loss in transmission. That’s where video upscaling comes in. By using advanced AI tools, you can easily upscale videos to 1080P, 4K, or even 8K in top-tier tools. If you wonder how to achieve this, this guide will walk you through basic video upscaling knowledge, a must-try video upscaler, and some practical tips.

Part 1. What is Video Upscaling?

AI video upscaling is an AI technology that enhances the resolution of videos. Video resolution refers to the number of pixels that make up an image on a screen, expressed as width x height (e.g., 1920 x 1080). 480P, 720P, 1080P, and 4K are common video resolution standards. While they correlate with video quality, quality also depends on factors like bitrate and compression. Standard video resolutions are primarily categorized into SD, HD, FHD, and UHD.

SD (480P), the standard definition, refers to a 640 x 480 video or image resolution with an aspect ratio of 4:3. It contains 307,200 pixels to store video graphics information.

HD, or high definition, is a step up from Standard Definition (SD). When we talk about HD, we mainly mean a resolution of 1280 x 720 pixels (720p).

FHD, or full HD, is a significant leap above HD videos. It usually refers to 1080P, which means a resolution of 1920 x 1080 pixels. Full HD is the current common resolution for mobile phones.

UHD, ultra HD, or 4K, means a resolution of 3840 x 2160 pixels - four times that of Full HD (1080p). This resolution provides the optimal visual experience.

In short, resolution plays a vital role in video quality and compatibility with various players.

Part 3. 3 Essential Tips for Best Video Upscaling Results

Tip 1. Begin with a high-quality source if possible.

The quality of your upscaled video heavily depends on the original footage. AI tools can’t entirely fix badly compressed videos; manual repair is also laborious. If possible, use the highest-quality version of your video before upscaling. The more detail your source has, the more accurately AI can reconstruct missing pixels.

Tip 2. Use trustworthy applications or AI tools.

Traditional upscaling methods stretch pixels, sometimes leading to blurry results. AI-powered tools like VidHex and Vmake can analyze patterns and textures and intelligently reconstruct missing details. An AI solution is far superior to manual methods to easily upscale videos to 4K or other professional levels.

Tip 3. Match upscaling to your content type.

Different videos need different upscaling approaches. For example, cartoons benefit from edge sharpening, while live-action videos need natural texture preservation. You can start with a short clip to test whether the tool suits your content type.

When it comes to video upscaling, the process always sounds troublesome. Thanks to advanced AI technology, the complexity comes to a standstill. An AI video upscaler can automatically detect and complete footage details and upscale videos to high or even ultra-high definition in minutes.
