4K Video Upscaling: What is it, How to do it, and it is worth upscaling?

We now have 4K videos on YouTube, Netflix, Blu-ray, etc., and we can record 4K videos with our phones, GoPros, and other cameras. Also, we have 4K smart TVs to watch those videos in a great watching experience. However, we still have old recordings or movies that are low in resolution. And, we must suffer watching them on 4K TVs due to the horrible quality.

The good news is, with the help of AI, we can do 4K Video upscaling and easily upscale low-resolution videos to 4K with almost the same watching experience as the native 4K videos.

What is 4K Video Upscaling?

Can we upscale a video to 4K? Definitely, and even with excellent results.

To learn that, let’s see what is upscaling first. The process of transforming a video or image with a lower resolution to one with a higher one is referred to as upscaling. Upscaling can be done with or without the assistance of artificial intelligence. So, 4K video upscaling is converting a low-resolution video to 4k. And the difference is whether it’s AI video upscaling or not.

You may notice that when we watch lower resolution videos on a 4K TV, your TV automatically upscales the videos to fit the 4K display. Most of the time, those processes are NON-AI 4K video upscaling. And, it does not give you a true 4K video-watching experience.

AI 4K video upscaling uses a different strategy than traditional methods with the help of AI. AI 4K upscaling uses AI deep learning models to take a low-resolution video to predict a high-resolution video that, when scaled down, will look exactly the same as the low-resolution video that it was trained on. With training on millions of videos, AI upscaled video can look more natural with high accuracy.

In this post, I’d like to show you two ways, one for PC & Mac and one for online, to do 4K, even 8K video upscaling; all are AI-based with excellent quality. Let’s go.

AI 4K Video Upscaling Software for PC/Mac/Online

My previous post on AI video enhancers recommended over 11 AI video upscaling software. However, some only upscale video to 1080p. If you want to do AI 4K upscaling, stay tuned.

4K Upscaling Software for PC and Mac

Topaz Video Enhance AI is definitely the best 4K video upscaling software. Since version 3, Topazlabs renames its Video Enhancer AI to Video AI. With over ten applicable AI models, it can upscale low, medium, and even high videos, whether progressive, interlaced, or computer generated, to 4K or even 8k. You can also enhance details to your native 4K videos. In this case, Topaz will denoise and deblock for you.

Topaz Video AI can do batch 4K video upscaling. You can also trim or preview the upscaling. In Topaz, you can add/reduce grains for the 4K upscale to be more natural.

You can do the AI 4K upscaling while removing the black bars by simply using “Crop” This way, you can turn your 4:3 video to 16:9. Also, you can customize the resolution and remove the black bars with this option.

How to Upscale Video to 4K on PC/Mac/Online

Can we upscale a video to 4K? Sure! Is it easy? Yes! In this part of the post, I’d like to show you in detail how to use AI video upscalers to get 4K videos. 

Upscale Video to 4K on PC/Mac

I have a very detailed guide on how to upscale video to 4K or even 8K in this post, along with the best settings for upscaling animation videos.  Also, you will learn tips on picking up the best AI model for 4K upscaling and making the upscaling faster. 

You can also check the below YouTube video to learn AI 4K upscaling.

Upscale Video to 4K online

I also have a detailed guide to upscale video to 4K online in my Pixop review here.

You will see a 4K video upscaling online alternative, which is Neural.love. It’s also good to go.

Is upscaling to 4K Worth it?

Does upscaling video improve quality? Is upscaling 4K the same as the native 4K video? 

I have a couple of YouTube videos showing how well AI video upscalers work for your old and low-resolution videos. And, it does improve quality. However, even with 4K video upscaling by AI, it’s not a native 4K video, and upscaling to 4K is NOT the same as the native 4K videos. 

But, the truth of the matter is that there are instances when your eyes alone will not be able to differentiate between an upscaled 4K video and a native 4K video while you are viewing both on the same 4K television screen. So, I do believe it’s worth doing AI 4K video upscaling.
