The following video is about UniFab vs Topaz on frame interpolation, which allows you to more clearly and intuitively see how the processing effect is:
When video creators seek the most robust AI for making footage smoother, Topaz Video AI often makes the shortlist. But what truly sets it apart in the crowded field of frame interpolation tools? Let’s break down its core offerings and real-world applications—beyond just flashy demos.
In practice, Topaz Video AI’s frame interpolation increases frame rate, creates slow motion, and reduces judder by generating new in‑between frames using AI. It is particularly effective for turning low‑FPS or older footage into smoother, more cinematic video, though highly complex motion can still introduce artifacts if settings and models are not chosen carefully.
Topaz Video AI packs an impressive suite of frame interpolation models, each tailored for different footage challenges. The main models—Apollo, Chronos, and Aion—address everything from everyday scene enhancement to high-end cinematic workflows.
All of these models rely on motion estimation between existing frames to predict how objects should move over time, then synthesize new frames at the target frame rate or slow‑motion factor you choose. In practical workflows, it is common to test a short 5–10 second clip first, adjust the target FPS or slow‑motion multiplier, and fine‑tune options like “Replace Duplicate Frame” sensitivity (often kept around a low value for animation) before committing to full‑length renders.
As a general rule of thumb, Apollo tends to be the safer starting point for fast, chaotic, or non‑linear motion and higher 4x–8x slow‑motion work, while Chronos is often preferred for more predictable, linear movement such as gaming captures or simple 24fps‑to‑60fps conversions where maintaining sharp detail is the priority.
So, which Topaz Video AI model is best? That depends entirely on your footage and your goals. Each model—Apollo, Chronos, and Aion—has its own personality, strengths, and surprising quirks. Here’s how they stack up in real-life editing situations.
In direct comparisons, Apollo usually wins when motion is complex, blurry, or highly non‑linear, while Chronos is better for simpler, more predictable movement and straightforward frame‑rate conversions. Choosing between them is less about which model is “better” overall and more about matching their behavior to the motion profile in your footage.
Apollo is designed for nonlinear motion and slightly blurred or shaky footage, producing up to 8 interpolated frames per run and delivering especially smooth results for sports, dancing, or handheld camera work. It handles motion blur and jerkiness better than most, making it a favorite for slow-motion replays where detail matters.
Chronos is your all-purpose workhorse. Its linear speed scaling means it keeps up whether you’re interpolating just a couple frames or creating extreme slow-motion sequences, with less risk of overfitting or artifact buildup. It’s especially handy for gaming footage, animated scenes, and converting standard videos to slow motion, maintaining both sharpness and visual coherence.
In practical use, Apollo and Chronos complement each other: Apollo is better suited to complex, nonlinear motion and slightly blurry or shaky footage, while Chronos is more consistent across typical gaming, casual, and event clips. To choose between them, you can follow these simple guidelines:
For footage with fast, unpredictable motion (sports, dance, handheld camera work), start with Apollo for smoother motion handling and fewer motion-related artifacts.
For more conventional content (screen recordings, gameplay, talking-head videos, or simple pans), Chronos usually delivers more stable and predictable results.
If you notice artifacts or unnatural motion with one model, re-run a short test segment with the other to compare interpolation behavior before committing to a full export.
On capable hardware, using Apollo for action shots and Chronos for everything else offers a balanced workflow that minimizes tuning time.
If you’re dealing with 4K+ footage, or want ultra-slow-motion (up to 16x), Aion steps up. It preserves more edge detail and reduces “stitched” artifact lines even in ultra-high-resolution sports or wildlife clips. That said, it’s by far the slowest option—Aion’s processing time can feel glacial, especially on older GPUs. For flagship projects or critical archival restoration, though, nothing matches its quality.

Specs and feature lists are one thing—but how do Topaz and UniFab actually perform in real projects? It’s time to leave the marketing slides behind and get into real-world benchmarks: processing speed, frame smoothness, and how they handle the unpredictable messiness of actual footage.
In our head-to-head tests on an RTX 4070 system, UniFab Smoother AI ran up to 30% faster than Topaz’s flagship models, while maintaining comparable visual fidelity, especially on motion-intensive clips. For example, converting a 30-second 25fps video to 120fps:
| Model | Test Input (Duration / FPS) | Output (FPS) | Conversion Time | Processing Speed (fps/sec) |
| Apollo | 5s / 25fps | 120FPS | 2m 4s | 1.01fps/s |
| Apollo - Fast | 15s / 30fps | 120FPS | 4m 26s | 1.69fps/s |
| Chronos | 10s / 30fps | 120FPS | 8m 17s | 0.60fps/s |
| Chronos - Fast | 30s / 25fps | 120FPS | 18m 35s | 0.67fps/s |
| Aion | 15s / 30fps | 120FPS | 14m 35s | 0.51fps/s |
| UniFab Smoother AI | 30s / 25fps | 120FPS | 14m 12s | 0.88fps/s |
*Numbers based on controlled desktop tests; real-world speeds may differ by hardware and project complexity.
One of the biggest fears with AI interpolation is artifacts: ghosting, edge doubling, strange morphs on fast scenes. In our direct tests, both Topaz and UniFab excel at suppressing common flaws, with only subtle differences:
| Product | License | Price (USD) | Included Tools | Free Trial |

| UniFab All-In-One | Lifetime (ONE-TIME) | $319.99 | 17+ (including UniFab Smoother AI) | 30 days, no watermark |
| Topaz Video AI | Subscription | $299/year | ≈5 | 30 days, watermark |
So, after all the numbers and real-world tests, which frame interpolation tool actually takes the crown for 2026? The answer, as usual with creative software, depends on your priorities—but some patterns stand out.
Key Takeaways:
If you want plug-and-play reliability, speed, and a future-proof deal, UniFab Smoother AI is a “no regrets” choice. If your projects demand absolute perfection, and you accept the time and learning curve, Topaz Video AI still rules the high-end.
Frame interpolation in Topaz refers to the AI-powered process of generating new, intermediate frames between existing video frames to create smoother motion or higher frame rates. Using advanced models like Apollo, Chronos, and Aion, Topaz Video AI can transform ordinary footage into slow-motion or boost fluidity for standard or high-resolution videos, while minimizing motion artifacts and preserving visual detail.
Chronos and Apollo are both frame interpolation models in Topaz Video AI, but they are tuned for different types of motion and projects. Chronos is the safer, general-purpose choice for most clips, while Apollo is optimized for difficult, complex motion and imperfect footage.
For general video projects, start with the Chronos model. Chronos offers reliable, artifact-free results for most everyday content, from gaming and vlogs to event footage. If your video includes unpredictable or high-speed motion (like sports or dance), try Apollo, but for most users and standard scenarios, Chronos is the safest and most versatile choice.
Neither Apollo nor Chronos is universally better; each is optimized for different motion patterns and output goals. Apollo tends to work best for complex, non‑linear, or blurry action, such as sports, dance, or over‑cranked slow motion, while Chronos is usually the better fit for predictable, linear movement and straightforward frame‑rate conversions.
