Step-by-Step: How to Upscale Old Videos Using AI

The landscape of video restoration has shifted dramatically. While it used to require expensive studio hardware, the software available in 2026 makes the process intuitive. Whether you are working with a family video from the 90s or a low-res clip from an early smartphone, the following steps will help you achieve the best results.

1. Select Your AI Upscaling Software: Choose a tool based on your hardware. For local processing, tools like HitPaw’s VikPea are industry leaders. For cloud-based needs, Artguru provides a seamless browser experience.
2. Import and Analyze: Upload your file. The AI will typically perform an initial scan to determine the level of grain, motion blur, and compression artifacts present in the original footage.
3. Choose an AI Model: Select a specific model tailored to your content. Use a "Face Model" for portraits, a "General Denoise Model" for landscape or street scenes, and a "Colorize Model" if you are working with black-and-white footage.
4. Set Output Resolution: Select your target resolution (e.g., 1080p, 4K, or 8K). According to recent technical reviews by MakeUseOf, modern GPUs can now handle these tasks natively through pre-installed driver features.
5. Preview and Export: Generate a short preview to ensure the sharpening isn't too aggressive. Once satisfied, render the final video to your desired format.

The Evolution of AI Video Enhancement in 2026

As we move through 2026, the technology behind video enhancement has moved from "experimental" to "standard." The primary driver of this change is the integration of AI directly into the hardware we use daily. According to a report by MakeUseOf in May 2026, many users already have high-end upscaling features installed on their systems via their GPU drivers, often without realizing it. This allows for real-time sharpening of old videos during playback, eliminating the need for lengthy rendering times for casual viewing.

Furthermore, the "intelligence" of these systems has improved. Earlier versions of AI upscaling often created a "waxy" look on human skin or distorted fine textures like grass or hair. The 2026 generation of generative models uses temporal consistency, meaning the AI looks at the frames before and after the one it is currently processing to ensure that the added detail remains stable and doesn't flicker. This is a crucial advancement for anyone looking at how to upscale old videos using AI for professional archival purposes.

The Rise of Native GPU Upscaling

One of the most significant shifts this year is the democratization of the technology. You no longer need a dedicated subscription for basic enhancement. Major GPU manufacturers have integrated AI-driven super-resolution directly into their control panels. This feature can take a standard-definition video stream and upscale it to 4K in real-time, which is particularly useful for streaming older content from platforms that haven't yet updated their libraries.

Comparing Top AI Video Upscalers of 2026

When deciding which tool to use, it is important to balance processing speed, cost, and the specific features offered. Some tools are better at "denoising" (removing the grain), while others excel at "restoration" (fixing tears or scratches in old film). Below is a comparison of the leading solutions currently available.

As noted by Beebom in their February 2026 review, tools like VikPea have introduced specialized "General Denoise" and "Face Restoration" models that operate independently. This allows users to target specific problems in a video—such as a blurry face in a crowd—without over-processing the rest of the environment. This level of granular control is what separates modern 2026 tools from the blunter instruments of previous years.

YouTube’s Impact on Video Quality Standards

In a massive move for the industry, YouTube recently deployed AI to upscale its vast library of legacy content. As reported by Forbes in late 2025, this deployment was driven by the surge in "living room viewing," where users watch YouTube on large 4K and 8K television sets. Low-resolution videos that looked acceptable on a phone screen in 2010 appear pixelated and unwatchable on a 75-inch TV. By using AI to upscale these videos server-side, YouTube ensures a consistent quality level across its platform.

However, this move has not been without its nuances. Lifehacker reported in October 2025 that YouTube's AI specifically targets low-res videos to bring them up to modern standards automatically. For purists who prefer the original look of vintage media, The Verge noted that YouTube has included an "opt-out" feature for creators. This allows filmmakers to preserve the "lo-fi" aesthetic of their work if the AI's sharpening interferes with their artistic vision. This balance between automated improvement and creative control is a hallmark of the 2026 tech ecosystem.

Cloud vs. Local AI Processing

When considering how to upscale old videos using AI, you must choose between cloud-based and local processing. Cloud tools like Artguru are excellent because they don't require a powerful computer; the heavy lifting is done on remote servers. Conversely, local software utilizes your own GPU. According to industry experts, local processing is generally preferred for sensitive or private family videos, as the data never leaves your machine, and it often provides more customization options for the final output.

Advanced Techniques: Denoising and Color Restoration

Upscaling is only one part of the restoration puzzle. Old videos often suffer from "noise"—the grainy, dancing dots that appear in low-light footage—and color fading. Modern AI enhancers now include dedicated modules for these specific issues. The Hans India highlighted Artguru as a leading "all-in-one" enhancer that handles both images and videos, making it a versatile choice for users who have a mix of old media to digitize.

Denoising Without Losing Detail

The challenge with denoising has always been the loss of sharpness; in the past, removing grain often meant making the video look blurry. In 2026, AI models use "spatial-temporal" analysis. This means the AI identifies what is actual noise and what is a fine detail (like the texture of a brick wall) by comparing it across multiple frames. If a "dot" appears in only one frame, the AI identifies it as noise and removes it. If it persists across frames, the AI recognizes it as a detail and preserves it.

AI Colorization for Vintage Film

For videos from the pre-color era, AI colorization has reached a point of startling realism. Instead of just "painting" colors onto a scene, the AI uses a massive database of historical images to identify objects. If it sees a 1940s car, it knows the common paint colors of that era and applies them accurately. This adds a layer of immersion to old videos that was previously impossible without a massive Hollywood budget.

Hardware Requirements for AI Upscaling in 2026

While AI has become more efficient, it still demands significant computational power. If you are looking to upscale a full-length feature film or hours of home movies, your hardware will play a major role in how long the process takes. Most software in 2026 is optimized for Neural Processing Units (NPUs) and modern GPUs. A dedicated graphics card with at least 8GB of VRAM is recommended for 4K upscaling to ensure the process doesn't take days to complete.

According to MakeUseOf, the latest drivers for consumer GPUs now include "Video Super Resolution" features that can be toggled on in the settings menu. This is the easiest way for the average user to experience AI upscaling without purchasing specialized software. It works by intercepting the video signal and applying a sharpening and upscaling filter before the image reaches your monitor. While not as powerful as a dedicated restorer like VikPea, it is a significant step forward for general usability.
