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.

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

Here are 7 AI video upscaling tools to helps users to upscale videos to 4K, up to 8K. Let's check them out.

2.1 AVCLabs Video Enhancer AI

Video enhancers tools can optimize the brightness, saturation, and contrast of videos to get a better result. And now the AI technology on video enhancing bring great progress. The AVCLabs Video Enhancer AI is the one you can not miss. It enables users to automatically upscale low-resolution and blurry homemade videos or old films from 480p, 720p to 4K, even up to 8k in a smart way.

Steps to upscale the videos' quality and resolution:

Step 1: Download and install AVCLabs Video Enhancer AI

First, please click the above button to download the AVCLabs Video Enhancer AI program on your computer. The file size is a little large so it needs a few minutes to download the file. Please be patient. And high-end dedicated graphics cards (NVIDIA GTX 1050 Ti and upper) are recommended strongly for GPU acceleration when processing the videos in high efficiency and saving time.

Step 2: Launch the Program and Import Videos

After installing, launch Video Enhancer AI and you will see the main interface like below. You can click on the Browse button to add videos to the program. Surly you can also drag and drop the video file to the square area to open the video in the program directly.

Step 3: Choose An AI Model and the Resolution

After loading the video files, you could view the options to upscale and enhance your video quality on the main window like the below image.

Step 4: Configure Output and Video Settings

Video Settings: manually adjust the brightness, saturation, contrast, and sharpen of your videos to enhance the visual quality. Or you can also crop to fill the frame and deinterlace.

Output Settings: set the output video format(MKV, MP4, AVI, MOV, WEBM), the encoder (H.264, H.265, VP9 Good, VP9 Best, AV1), the bitrate, audio settings, as well as the output path.

Step 5: Upscale the Video Quality and Resolution with AI

After the simple settings, click Start Processing. The program will start to enhance the quality of movies. On the processing interface, you can see the original and processed video in a comparing-view. You also can see the progress bar, processing time, etc.

After the processing is completed, you can click "Open Folder" to check the enhanced video. With this AI-based video enhancer, you can get better video quality and bring you a satisfactory result. And all the enhanced work is done by AI automatically so you are not required any skill.
