When I first looked into Topaz Video AI, I had the same questions most people do: Is it really worth $299 per year? And is the quality actually that much better than cheaper alternatives?
I spent time testing Topaz Video AI on real footage, across multiple models and scenarios—from upscaling old clips to handling noisy, low-light video. In this review, I’ll share what genuinely impressed me, what frustrated me, and who I think should (and shouldn’t) buy it. Plus, I'll compare it to the best Topaz Video Enhance AI Alternative on the market: UniFab Video Enhancer AI.
If you’re on the fence about Topaz—or looking for a smarter alternative—this review should save you both time and money.
Topaz Video AI is an advanced AI video enhancer developed by Topaz Labs, designed to upscale video resolution and improve overall quality. It leverages specialized AI models such as Nyx, Apollo, Chronos, and others to perform noise reduction, sharpening, detail recovery, frame interpolation, and stabilization. Featuring a redesigned user interface, multi-threaded architecture, and customizable presets, Topaz Video AI delivers an efficient and powerful solution for video enhancement. Formerly known as Topaz Video Enhance AI, it is now widely used to restore old or low‑quality footage, convert HD to 4K or 8K, and create smooth slow motion, making it especially appealing to filmmakers, content creators, and professionals who need high‑end restoration rather than casual editing.
At a glance: it’s a desktop app for Windows and macOS that runs processing locally, using model‑based upscaling, denoising, stabilization, and frame interpolation to rehabilitate low‑quality footage.
Topaz Video AI has evolved from a simple upscaler into a professional video restoration suite. In 2026, the software features 19+ specialized AI models categorized by their primary "superpower."
To help you choose the right tool for your footage, I've summarized the latest model lineup below, including the newest Starlight and Rhea series.
These models focus on rebuilding lost pixels, textures, and clarity when moving from SD to HD, 4K, or even 8K.
| AI Model | Primary Purpose | Best Used For... |
| Proteus | The All-Rounder | General enhancement with manual sliders for sharpening, de-halo, and de-noise. |
| Iris | Portrait Specialist | Best for low-to-medium quality footage where faces appear blurry or "pixelated." |
| Nyx | Low-Light Master | High-fidelity denoising that preserves natural textures instead of making them look "plastic." |
| Rhea / Rhea XL | 4K/8K Texture King | Designed for 4x upscaling of high-quality sources, excelling at delicate fabrics, hair, and skin. |
| Starlight (New) | Diffusion Restoration | A generative model for extremely degraded sources (VHS, 360p) that "reimagines" missing details. |
| Artemis | Grain Preservation | Balanced noise reduction for clean, progressive sources; great for keeping a filmic look. |
| Gaia | High-Quality Upscale | Ideal for upscaling already "clean" footage (like 1080p high-bitrate) to 4K. |
These models handle the "time" dimension of your video, adding frames for smoothness or slow motion.
Beyond upscaling, these models fix specific optical or digital flaws.
Now that we've covered the technical "brain" behind the software, let's look at how these models perform in real-world benchmarks.
To see how Topaz Video AI performs in real-world scenarios, I personally tested several of its core AI models using different types of video footage on my own setup (NVIDIA GeForce RTX 4070 GPU and AMD Ryzen 7 5700G CPU). Below are the main observations from my tests. For most examples, I captured the first frame from both the original and enhanced videos to make the improvements easier to judge at a glance.
In general, Topaz Video AI delivers noticeably higher visual quality than the original footage, but processing speed and stability are highly dependent on GPU power and workflow settings.
Proteus Model Purpose: Proteus Model supports upgrade and sharpen medium quality video by fixing compression artifacts, anti-aliasing and denoise. Best used when you need a balanced enhancer that recovers detail without over‑smoothing.
Processing Time: Approximately 12–14 minutes to upscale a 30-second 720p 60fps video to 4K.
Effect
The Proteus AI model enhances video details, making textures sharper and improving overall clarity.
Limitations
It offers balanced enhancements across the video, without focusing on one specific feature.
Facial restoration is limited, with only slight improvement in clarity.
Nyx Model Purpose: Topaz Nyx Model is suitable for noise reduction and sharpening for low quality video.
Test Clip: For this test, I used a low-light video clip with noticeable grain and compression noise, recorded at 720p and 25fps. The footage contains visible noise in darker areas and soft edges.
Processing Time: About 1 minute for a 30-second 25fps video.
Effect
Noise Reduction: The Nyx AI model delivers excellent restoration results, effectively eliminating nearly all noise from the video.
Sharpening: This model sharpens edges and contours, enhancing the perceived resolution and clarity of the video.
Limitations
Possible Over-Smoothing: With footage that has high noise levels, the Nyx AI model may over-smooth the image, causing a loss of fine details.
Limited Impact on Well-Lit Footage: Nyx works well in low light, but its benefits are less noticeable in well-lit footage with minimal noise.
Iris Model Purpose: Iris is a general enhancement model for reducing noise and compression. It is great for recovering faces in low to medium quality footage, which is the best model for face recovery.
Test Clip: For this test, I used a low-resolution 720p video clip with visible compression artifacts and slightly blurred facial details, recorded at 25fps.
Processing Time: Around 4 minutes to upscale a 30-second 720p 25fps video to 4K.
Effect
Enhanced Facial Details: It sharpens facial features like eyes, lips, and skin texture, making faces more detailed.
Improved Saturation and Contrast: It boosts saturation and contrast, giving the video a soft, realistic look.
Limitations
Artificial Appearance: The model enhances face detail well, but at higher resolutions like 4K, the effect can seem over-processed and lack a natural feel.
Themis Model Purpose: Themis supports reducing motion blur caused by panning, rotation, or zoom.
Test Clip: For this test, I used a skiing video with fast downhill movement and frequent camera panning, recorded at 720p and 25fps. The clip contains noticeable motion blur around moving subjects and background details
Processing Time: 30 seconds to 1 minute for a 30-second 720p 25fps video.
Effect
We can see the subtle difference between the before and after, where the edges of the original video were slightly blurred. The restoration has sharpened the edges and eliminated motion artifacts.
Limitations
Stuble Changes: It effectively stabilizes and reduces noise, but the overall visual changes may be subtle, making it ideal for users looking for moderate improvements rather than dramatic transformations.
Hyperion Model Purpose: Topaz Hyperion is a new model launched by Topaz Video AI for converting SDR videos to HDR. The early beta version delivered mediocre results, with overly high saturation and brightness, severe warm color overflow, and minimal difference from the original SDR footage.
The official release shows noticeable improvements in brightness and contrast. Shadow areas appear brighter, while highlights tend to be overexposed, making the image sharper but at the cost of losing some details. Colors are more intense—especially warmer tones—which may lead to color overflow or overcorrection. Compared to native HDR, the Hyperion style is more aggressive.
With default settings, the latest version takes about 1 to 1.5 times the original video duration to process. If parameters are adjusted, conversion time increases exponentially, resulting in a significantly higher time cost.
Effect
Enhances colors and contrast, making the image more vibrant.
Delivers a natural, realistic HDR look without over-saturation.
Limitations
Some content may not benefit from the conversion as much as others.
I also conducted a comparative analysis of the processing performance among the different Topaz Video AI models to help you choose the most suitable one based on your needs.
Among the various AI models, Rhea, Proteus, and Iris are commonly used for facial restoration and detail enhancement. Here is how they compare:
Overall, all models offer smoother facial restoration compared to the original video, significantly improving the character's appearance.
When zoomed in, Proteus and Iris both show some facial distortion or warping after processing, though Iris tends to maintain better clarity.
Nyx and Artemis are both AI models focused on noise reduction.
The Topaz Nyx model effectively removes most noise but relies on aggressive smoothing, which reduces image detail and realism—resulting in a cleaner yet less detailed picture.
