AI Video Upscaling: How to Easily AI Upscale Video to 1080P and 4K
Is there any useful tool for AI video upscaling? I’m trying to find a tool for AI video upscaling so as to upscale some old, really, really low-res films to high resolution, like 1080p, or 4K. I have used some online tools to upscale low-res videos before, but with little success.
Although there are many kinds of AI video upscaling tools in the market, such as AI-based video upscaling software, AI video upscaling extension, online AI video upscaling, and non-AI video upscaling software, the truth turns out that the AI video upscaling software work much better than non-AI software and online AI video upscaler. What's more, the AI video upscaling tool is easy to use and delivers the best output results with more video details enhanced. Here we go.
What is video upscaling? As a simple example, if you watch HD movies in 720p/1080p on a 4K screen, the image has to be stretched to match the TV’s pixels. In this stretched process, upscaling is done by the streaming device (smart TV or streaming media player). However, the upscaling algorithms used by streaming devices are too basic to deliver the high-definition content for 4K TVs. It simply fills out all the pixels of the higher resolution display, the video contents and details can not be significantly improved by basic/traditional upscaling algorithms.
AI video upscaling is different. Given a low-resolution video, the deep learning AI model can predict a high resolution with high accuracy. It can not only upscale the resolution to fill out all the missing pixels, but also produce incredible sharpness and enhance details that no traditional upscaling tools can achieve. AI video upscaling has been used on some smart TVs like Samsung, Sony, LG, and Panasonic, as well as the AI-based video&photo enhancer. In this article, we will mainly talk about how to AI upscale video by the dedicated AI upscaling software (desktop, extension and online).
With AI algorithms built into the AI video upscaling software, they can upscale and enhance lower-resolution videos, like upscaling SD to full HD, HD to 4K or 8K. The AI algorithms can intelligently populate all the extra pixels and produce stunning visuals. The AI technology from AI video upscaling software process a video by using an artificial neural network, which simulates the human brain to steadily build a stronger understanding of video characteristics.
AI video upscaling software equipped with machine learning-based AI upscaling to analyze and enhance the content rather than stretching it to fill the pixels. AI upscaling populates the additional pixels and improves the resolution. By AI upscaling old videos, documentaries, old films, animes, or TV shows, you can get the enhanced, sharpened visuals that are incredibly crisp and rich.
With AI video upscaling started to be popular in both the entertainment and commercial video industry, the individuals may need to upscale old and low-res films for watching on the 4K/8K displays for clear visual effects, while the enterprises need to upscale and enhance all forms of digital video including CCTV systems, cell phones and dashcam videos used as evidence. In the following part, we will show you how to easily AI upscale videos with the best AI upscaler.
AVCLabs Video Enhancer AI is an AI-based AI video upscaling software that uses a neural network to upscale video from 480P to 1080P, 720P to 4K, or up to 8K, with super-resolution upscaling and multi-frame enhancement. Super Resolution can recover a high-resolution video from a given low-resolution material and create extra pixel data to fill in the missing gaps. Multi-frame enhancement uses the multi-frame convolutional neural network to enhance the video quality, remove motion artifacts, stabilize video shake, remove overlay noise and grain to get more natural results that classical programming cannot easily achieve.
Why Choose AVCLabs Video Enhancer AI
With AI video enhancer, you can not only enhance and improve video quality 100% automatically, but also upscale video resolution by up to 4K or 8K losslessly with every detail enhanced. With the well-trained AI filters and AI algorithms, the Video Enhancer AI can boost the video quality to the max, and all your old videos can be restored to come to life again.
- Automatic enhance video quality with the power of AI
- Enlarge video resolution up to 8K with the best quality kept

How to Easily AI Upscale Video with AVCLabs Video Enhancer AI
Step 1: Add source videos to AVCLabs
Before downloading AVCLabs Video Enhancer AI on your computer, please check the system and hardware requirements of the program.
Launch AVCLabs Video Enhancer AI, then click the "Browse" button to import your source footage from local drive.
Step 2: Choose AI model and configure output settings
In the upper-right panel of the application, "Upscale" model is checked by default. And you can check "Denoise" and Face Refinement" if necessary.
Under "Upscale" model, there are four advanced options you can choose: Standard, Ultra, Standard (Multi-Frame), and Ultra (Multi-Frame)
Standard: Frame-by-frame processing, at fast speed.
Ultra: Frame-by-frame HD models, a slightly slower speed, recommended if you have no requirements on processing speed.
Standard (Multi-Frame): Process multiple frames at a time, effectively reducing the amount of flicker, at a fast speed, highly recommended if your computer is in high configuration.
Ultra (Multi-Frame): HD model that processes multiple frames at a time, effectively reducing the amount of flicker, at a slower speed.
Unfold the Video Size to adjust the output size to 720p, 1080p, 2K, QXGA, Quad HD, WQXGA, UHD, 4K, or 8K.
Then choose the output format as MP4(H.264), AVI(Uncompressed). AVI(Uncompressed) will result in massive file size because it will be preserving all visual details.
You can also trim the footage to preserve the part you want and save the processing time.
Step 3: Start AI upscaling video
Click the "Start Processing" button to render your video. The program will start processing frames of your source video and assembling the upscaled video. After the conversion is completed, you can open the file folder to check the AI upscaled video.
