The State of AI Video Upscaling in September 2026
AI video upscaling has matured dramatically over the past two years, moving from a niche experimental technique to a mainstream feature embedded in smartphones, GPUs, and dedicated software suites. In 2026, the core promise remains the same: take a low-resolution video and use neural networks to reconstruct detail that was never originally captured. The difference now is that the results are often indistinguishable from native footage, provided the source material is not catastrophically degraded. Nvidia's DLSS 4 technology, which combines AI upscaling with multi-frame generation, has set a new benchmark for real-time rendering, though its application to pre-recorded video content remains limited to supported titles and platforms. On the mobile side, Samsung's ProScaler, introduced with the Galaxy S25 series, brings on-device AI upscaling to video playback and recording, targeting QHD+ and 4K output from lower-resolution inputs. The technology relies on the Galaxy S25's glass-ceramic materials and improved display density to present consistent visuals, though early reports from Samsung's own testing suggest the gains are most visible on screens larger than 6.5 inches. Adobe's acquisition of Topaz Labs in 2025 has consolidated much of the desktop video enhancement market under one roof, giving Premiere Pro and After Effects users direct access to Topaz's AI models without leaving the editing timeline. The result is a fragmented but rapidly improving ecosystem where the right tool depends heavily on whether you are processing a single clip or rendering a feature-length project.

How AI Upscaling Actually Works in 2026
At its foundation, AI video upscaling uses convolutional neural networks or transformer-based architectures trained on pairs of low-resolution and high-resolution video frames. The model learns patterns of detail—edges, textures, grain structure—and attempts to reconstruct plausible high-frequency information when scaling beyond the original resolution. In 2026, the leading approaches fall into two broad categories: frame-by-frame enhancement and motion-compensated temporal processing. Frame-by-frame methods analyze each image independently, which is faster but can introduce flickering or inconsistent detail across frames. Temporal methods, used by Topaz Video AI and similar tools, track movement across multiple frames to stabilize the output, though they require more processing power and can blur fast motion if the model is not well-tuned. Nvidia's DLSS 4 takes a different approach by generating entirely new frames between existing ones, effectively increasing both resolution and frame rate simultaneously. This technique, while impressive for gaming, introduces artifacts when applied to real-world footage because the AI is inventing motion that may not match the original scene. Samsung's ProScaler, embedded in the Galaxy S25+, S25 Edge, and S25 Ultra, uses a hybrid on-device model that balances speed and quality, targeting consistent output at QHD+ rather than full 4K reconstruction. The practical takeaway is that no single method dominates; the best results come from matching the algorithm to the content type and the hardware available.
Head-to-Head Comparison of Leading AI Upscalers
Choosing an AI video upscaler in 2026 requires weighing factors like output resolution, processing speed, hardware requirements, and pricing model. Topaz Video AI remains the most widely tested desktop solution, supporting up to 4K output with models optimized for animation, live-action, and low-light footage. Its Pro version, bundled with Adobe's Creative Cloud following the Topaz acquisition, offers accelerated processing on Nvidia RTX 40 and 50 series GPUs, though users report diminishing returns beyond the RTX 4080. On the mobile front, Samsung's ProScaler provides a compelling built-in option for Galaxy S25 owners, but it is limited to playback and recording scenarios rather than post-production workflows. For users seeking free or open-source alternatives, tools like Video2X and Real-ESRGAN offer respectable results, though they demand technical setup and often produce inconsistent output on complex scenes. The table below summarizes the key differences between the major options available in mid-2026.
| Feature | Topaz Video AI Pro | Samsung ProScaler | Nvidia DLSS 4 | Video2X (Open Source) |
|---|---|---|---|---|
| Max Output Resolution | 4K | QHD+ | 4K (gaming only) | 4K |
| Hardware Requirement | RTX 3060+ recommended | Galaxy S25 series | RTX 50 series | GPU optional, CPU slower |
| Processing Speed | 1-5 fps (4K) | Real-time | Real-time | 0.1-1 fps |
| Price | Subscription / one-time | Included with device | Included with GPU | Free |
| Best For | Post-production | Mobile playback | Gaming | Budget users |
Getting started with AI video upscaling in 2026 is straightforward for most users, but achieving the best results requires attention to source quality and settings. Begin by assessing your source footage: AI upscalers perform best on material that is at least 720p with stable framing and reasonable bitrate. Footage that is heavily compressed, noisy, or interlaced will produce artifacts regardless of the model used. For desktop workflows, Topaz Video AI offers a guided interface where you select the target resolution, choose an AI model tailored to your content type, and adjust the strength of enhancement. A setting between 30 and 50 percent strength often preserves natural texture while reducing compression artifacts, whereas pushing to 100 percent can create an over-processed, waxy appearance similar to the "plastic look" that PetaPixel's testing identified in earlier generations of upscalers. Mobile users on the Galaxy S25 series can enable ProScaler in the display settings, though the effect is most noticeable when streaming content originally encoded below QHD+. For gamers, DLSS 4 is accessible through the Nvidia Control Panel or in-game settings, but it should be reserved for titles that explicitly support the feature rather than applied to general video playback. In all cases, exporting the upscaled video in a high-bitrate codec like H.265 or AV1 helps preserve the gains during subsequent editing or sharing.
Common Mistakes That Undermine Upscaling Results
Even the best AI upscaler will produce disappointing output if the user makes avoidable mistakes in preparation or settings. One of the most frequent errors is attempting to upscale footage that is already degraded by heavy compression or low bitrate; the AI will amplify artifacts rather than remove them, resulting in a final image that looks worse than the source. Another common pitfall is ignoring frame rate consistency, as AI models trained on 30 fps footage can stutter or produce ghosting when applied to 60 fps material without proper temporal handling. Users of Topaz Video AI sometimes over-rely on the default settings, which are optimized for general use but may not suit specific content like animation or sports footage. Switching to a content-specific model, such as the animation or low-light preset, can dramatically improve detail retention and reduce haloing around edges. On the hardware side, assuming that any GPU will deliver real-time upscaling is a mistake; Nvidia's DLSS 4 requires RTX 50 series cards for full functionality, and older cards may fall back to slower, less effective modes. Finally, neglecting color space and bit depth during export can undo the quality gains, as upscaled footage saved in 8-bit formats may band in gradients that the AI worked hard to reconstruct. Taking the time to match settings to the source material and export requirements is the single most reliable way to avoid these traps.
When to Use AI Upscaling and When to Avoid It
AI video upscaling shines in specific scenarios but is not a universal fix for every video quality problem. The strongest use case is restoring archival or low-resolution footage where the original capture quality was limited by older hardware or bandwidth constraints. Projects like the colorization and upscaling of a 109-year-old New York City video to 4K and 60fps, documented by PetaPixel in 2020, demonstrate the dramatic improvement possible when the source is stable and the AI model is well-suited to the era's film grain and resolution characteristics. In 2026, similar workflows are accessible to content creators working with vintage home video, early digital footage, or compressed social media exports. However, AI upscaling is not a substitute for shooting in the highest quality possible from the start. A 4K native recording will always outperform a 1080p upscale, and the computational cost of processing hours of footage can be substantial. For live production or real-time streaming, the latency introduced by AI upscaling may be unacceptable, particularly on hardware that lacks dedicated AI accelerators. Users should also be cautious about upscaling animated content, where hard edges and flat color fields can confuse AI models and produce flickering or injected detail that does not match the original artist's intent. In these cases, a simpler sharpening filter or a dedicated animation upscaler may yield more faithful results.
Cost and Accessibility of AI Upscaling Tools
The pricing landscape for AI video upscaling in 2026 reflects a split between subscription-based professional tools and free open-source alternatives. Topaz Video AI Pro, now integrated into Adobe's ecosystem, carries a subscription fee that varies by plan but typically adds $99 to $199 per year on top of Creative Cloud membership. For professional editors and studios, this cost is often justified by the time saved and the quality gained, particularly when processing large volumes of footage. Nvidia's DLSS 4 is included with RTX 50 series GPUs, which retail from approximately $550 for the RTX 5070 to over $1,500 for the RTX 5090, making it accessible only to users with recent hardware. Samsung's ProScaler is effectively free for Galaxy S25 owners, though the device itself starts at around $850 for the S25+, representing a significant upfront investment for a feature that primarily enhances playback rather than production workflows. Open-source tools like Video2X and Real-ESRGAN remain free to use but require technical knowledge to install and configure, and they lack the polished interfaces and customer support of commercial products. For casual users or those on a tight budget, free tools can produce satisfactory results, but the learning curve and slower processing speeds mean that professional workflows still gravitate toward paid solutions. As of September 2026, the trend is toward bundling AI upscaling into broader software and hardware packages rather than selling it as a standalone product, which benefits users who already own compatible devices but limits options for those starting from scratch.
Looking Ahead: What 2027 May Bring
The trajectory of AI video upscaling suggests that 2027 will bring faster processing, higher quality output, and deeper integration into everyday devices. Nvidia's roadmap indicates continued refinement of DLSS technology, with rumors of DLSS 5 focusing on improved temporal stability and reduced artifact generation in non-gaming applications. Adobe's investment in Topaz Labs signals a commitment to making AI enhancement a standard feature in creative software, potentially extending upscaling capabilities to mobile apps and web-based editors. Samsung's ProScaler may expand to older Galaxy models through software updates, though hardware limitations will likely cap the quality gains on devices without dedicated AI processing units. On the research front, transformer-based models are increasingly replacing convolutional networks, offering better handling of complex motion and fine detail at the cost of higher computational requirements. For the average user, the practical implication is that AI upscaling will become less of a specialized skill and more of a background process, automatically applied during playback or export without requiring manual intervention. However, the fundamental limitation remains: AI can only reconstruct plausible detail, not recover information that was never captured. As 2026 draws to a close, the best strategy for content creators is to shoot and record at the highest quality their workflow allows, using AI upscaling as a powerful but imperfect tool for rescue and enhancement rather than a replacement for good source material.
