10 Best Free & Paid AI Video Upscaler to Upscale Video to 4K/8K

Summary: Low-resolution videos often look blurry, blocky, or noisy on today’s HD and 4K screens. AI video upscaling software can improve them by sharpening details, reducing artifacts, and reconstructing textures that traditional upscaling cannot restore. To see which tools actually deliver better results, we tested popular AI video upscalers on real low-quality footage and picked the 10 best options in this guide.

Old SD videos, compressed clips, and low-bitrate recordings often fall apart on modern displays. Faces look soft, edges turn jagged, and compression noise becomes much more obvious.

Traditional upscaling only stretches pixels to fit a larger resolution, so it rarely adds real detail. AI video upscaling works differently: it analyzes each frame and uses trained models to rebuild edges, textures, and clarity for a more natural-looking result.

But not all AI upscalers perform the same. Some are better at restoring old footage, some handle anime or game videos better, and some upscale to 4K well but are slow or restrictive. To find the tools actually worth using, we recently tested leading AI video upscalers with real low-resolution, compressed, and older video clips, comparing output quality, speed, ease of use, and export limits.

Based on those results, this guide rounds up the 10 best AI video upscalers to help you choose the right one for cleaner HD or 4K output.

💡 How We Test

To make this roundup as practical and trustworthy as possible, we tested each AI video upscaler under the same hardware conditions using multiple types of low-quality footage instead of relying on a single sample clip.

• Test environment: AMD Ryzen 5 5600X, 64GB RAM, AMD Radeon RX 6700 XT 8GB, Windows 11 64-bit.
• Test video: We used five types of footage that commonly need enhancement in real use: anime video, movie footage, old video, low-light night footage, and low-resolution phone video.
• Test criteria: We evaluated each software based on its ability to upscale the video to 4K, reduce blur and noise, improve stability, and preserve or restore fine details. Tools were also assessed for processing speed, ease of use, and format compatibility.

9. Real-ESRGAN

Best open source and free AI video upscaler to restore and upscale real-world or old video footage.

Rating by Aiarty

Platform: Windows, Linux, and MacOS

One of the biggest strengths of Real-ESRGAN is that it was specifically designed for real-world degraded media rather than ideal synthetic downscales. According to its authors, the model is trained using a high-order degradation pipeline that simulates blur, noise, JPEG compression artifacts, and other real-world distortions. This allows it to better reconstruct textures and reduce common artifacts in compressed or low-quality footage.

In practice, Real-ESRGAN generally performs well on degraded content such as older recordings, low-bitrate web videos, compressed footage, and anime, where its training helps recover cleaner edges and more natural-looking details. Although originally developed for image super-resolution, it has become one of the most widely adopted open-source AI models for video enhancement by processing frames individually. It is often integrated into video restoration workflows alongside frame interpolation or temporal stabilization tools to help minimize flickering between frames.

However, Real-ESRGAN is not without its trade-offs. Like most GAN-based upscalers, it may hallucinate textures or fine details that were not present in the original source. When used for frame-by-frame video upscaling, inconsistent detail generation can also introduce temporal flickering unless additional post-processing or stabilization is applied. Processing high-resolution videos remains computationally demanding and typically requires a modern GPU for practical performance.

Overall, Real-ESRGAN remains one of the most influential and well-supported open-source AI upscalers, offering a strong foundation for restoring compressed, noisy, and low-quality footage. While newer community-developed models and fine-tuned variants, such as neosr or 4x-UltraSharp, often deliver better results for specific content types, Real-ESRGAN continues to be a reliable baseline thanks to its mature ecosystem, broad compatibility, and consistent performance. Achieving the best results usually involves testing different models and adjusting parameters such as scale factor, denoise strength, and temporal smoothing based on the source material.

My Experience with Real-ESRGAN's Video Upscaling

After testing Real-ESRGAN on a variety of video clips, I found that it provided reliable improvements for compressed and low-quality footage rather than dramatic transformations. Older SD videos appeared cleaner, with reduced compression artifacts and moderately improved detail, although the results varied depending on the source material. Upscaling a 480p clip to 1080p produced a noticeably clearer image, but some of the finer textures were AI-generated approximations rather than faithful restorations.

Because Real-ESRGAN processes videos frame by frame, fast-moving scenes can occasionally show inconsistent textures or slight flickering without additional temporal processing. Compared with today's latest commercial AI upscalers and newer community-trained models, the original Real-ESRGAN no longer delivers the strongest image quality in every scenario. Even so, it remains a solid open-source baseline for restoring compressed or degraded footage and continues to be widely used in many video enhancement workflows.

10. Adobe Premiere Pro

Best for the top professionals to edit videos.

Rating: 9.0/10 by PCmag

Platform: Windows; Mac

Adobe Premiere Pro is a professional video editing platform that also provides basic tools for resolution adjustment and visual enhancement, rather than a dedicated AI video upscaler. In practical use, the commonly used “Fit to Frame” function is essentially a traditional scaling operation (previously referred to as Scale), which resizes footage to match the sequence resolution using standard interpolation methods instead of AI-based detail reconstruction.

While Premiere Pro includes several AI-assisted features powered by Adobe Sensei, such as Auto Reframe for intelligent cropping, Scene Edit Detection for automatic shot segmentation, and various content-aware editing tools. These functions are primarily designed to assist with editing workflows rather than true super-resolution. Color and image adjustments are handled through the Lumetri Color panel, which provides professional-grade grading and correction tools but does not generate new image detail.

In terms of resolution handling, Premiere Pro supports working with 4K, 8K, and higher-resolution timelines, allowing editors to upscale or downscale footage within a flexible editing environment. However, the visual improvement of lower-resolution clips depends mainly on interpolation and color enhancement rather than AI-based reconstruction. As a result, it is best understood as a professional editing solution with scaling capabilities, rather than a dedicated AI video upscaling tool.

Features:

• AI video upscaling to 4K, 8K, and higher resolutions.
• Auto Reframe and Scene Edit Detection for intelligent frame adjustments.
• Lumetri Color panel for precise color grading and tonal enhancement.
• Integrated noise reduction and motion stabilization for smoother playback.
• Supports both compressed and archival footage, maintaining natural textures.
• Seamless integration with After Effects for advanced compositing and visual effects.

Pros:

• Offers professional-grade upscaling while preserving detail and natural motion.
• Flexible control over frame-level adjustments and color, beyond simple AI upscaling.
• Handles large, multi-layered projects efficiently on high-performance systems.
• Enables recovery of older or low-resolution footage to near-modern standards.
• Combines AI upscaling with editing workflow, avoiding the need for multiple software.

Cons:

• Steep learning curve for beginners.
• High system requirements; requires robust CPU/GPU for smooth 4K/8K upscaling.
• Processing and rendering times can be long for ultra-high-resolution videos.
• Less immediate “one-click” automation compared to dedicated AI upscalers.
• The 'audio out of sync in Premiere' error occurs occasionally.

My Experience with Adobe Premiere Pro's AI Video Upscaling

Using Adobe Premiere Pro for video upscaling is best understood as part of a professional editing workflow rather than a dedicated AI enhancement process. In testing, the commonly used "Fit to Frame" function (previously known as Scale) simply resizes footage to match the sequence resolution using traditional interpolation methods. As a result, upscaling 720p or 1080p footage to 4K or 8K does not introduce new details in the way AI-based upscalers do, but instead relies on resizing combined with manual color grading, sharpening, and compositing tools.

Where Premiere Pro excels is in flexibility. Editors can combine basic scaling with Lumetri Color adjustments, motion controls, and other timeline-based editing tools to refine the final output within a single environment. This makes it suitable for integrating lower-resolution footage into professional 4K or higher-resolution projects, especially when upscaling is only one part of a larger editing workflow. However, compared with dedicated AI video upscalers, the visual improvement is more limited and depends heavily on manual tuning rather than automated reconstruction.

On the downside, achieving high-quality results requires both experience and sufficient hardware performance, particularly when working with high-resolution timelines or complex effects. While the learning curve can be steep for beginners, Premiere Pro remains a powerful solution for professional editors who prioritize precise control over editing and post-production rather than one-click AI enhancement.

What Is AI Video Upscaling

AI video upscaling is a technique that uses artificial intelligence (AI) algorithms to upscale video from HD to 1080p/4K.

Traditional video upscaling involves implementing algorithms designed to fill the additional pixels with similar visual information in a way that makes the resulting video look clearer and more detailed, or create interstitial pixels to produce a smoother transition between low-resolution pixels. While an AI video upscaler performs the same function, it possesses an improved capability to recognize the image context and enhance the intricacy of the output. This is achieved through the utilization of deep machine learning models that have been trained on extensive datasets of high-resolution images and videos. These models learn to identify patterns and features in images and use the collected knowledge to generate higher-quality versions of the input video, making it a powerful video enhancer.

Take a piece of an old family video that was recorded on VHS tapes. The tape comes in low resolutions and has degraded over time, resulting in blurry and pixelated videos. Using AI video upscaling software, or an AI video enhancer, you can feed these low-resolution videos into the algorithm. The algorithm will then dissect the video into individual frames, analyze and predict the missing information in these areas, and cross-reference them with images or video footage from other frames or the training dataset to identify pixel patterns resembling those found. Subsequently, it adds additional pixels to generate a higher-resolution rendition of the original video, effectively AI upscaling videos and providing significant video enhancement.
