AI frame interpolation is a technique that uses artificial intelligence to generate additional frames between existing ones in a video. Unlike traditional frame duplication, which causes ghosting or static blur, AI frame interpolation software can predict how the movement would naturally occur and synthesize new frames accordingly by analyzing motion paths, objects, and scene context. This results in smoother transitions and higher frame rates, transforming choppy or low-FPS footage into fluid, lifelike motion.
Although traditional frame interpolation methods are also effective, they require more time and effort, and the results are inferior to AI frame interpolation software. Therefore, this article will recommend 12 best AI frame interpolation software tools to help you improve video quality.
The table below reveals how we selected and ranked our top 3 choices.

We tested three popular AI frame interpolation tools under the same conditions to compare their real performance. The test involved converting a 1-minute 30fps video to 60fps without changing the resolution. The setup used was:
UniFab: Delivered the most visually consistent and natural results. While slow-motion playback reveals some motion artifacts and slight differences from original frames, the AI-generated frames maintain high object integrity—especially noticeable on fast-moving objects like a basketball.
Topaz: Produces decent results with moderate motion artifacts. In slow motion, AI-generated frames are visibly different from the originals, and object integrity is weaker compared to UniFab.
HitPaw: Lower visual quality with more evident motion artifacts and unstable transitions. AI-generated frames diverge more significantly from the real footage, and fast-moving objects appear fragmented.
| Tool | Model Used | Conversion Time | Visual Quality | Artifacts | AI Frame Generation Accuracy |
|---|---|---|---|---|---|
| UniFab Smoother AI | Smoother AI | 3 min | ⭐️⭐️⭐️⭐️⭐️ (High) | Minimal | Very Accurate |
| Topaz Video AI | Chronos Fast | 2 min 30 sec | ⭐️⭐️⭐️⭐️ (Moderate) | Noticeable | Decent |
| HitPaw Video Enhancer | Frame Rate Interpolation | 3 min | ⭐️⭐️⭐️ (Low) | High | Less Accurate |
Summary:
Among the three, UniFab Smoother AI delivered the smoothest and most natural results with minimal ghosting and artifacting. Topaz Video AI performed well but showed a drop in object consistency. HitPaw lagged behind in visual fidelity and introduced more noticeable visual flaws.

Frame interpolation is a video processing technique that adds new frames between existing ones to increase the frame rate and make motion appear smoother. This method is especially useful for low frame rate videos (like 24fps or 30fps) that appear choppy or laggy on modern high-refresh-rate displays.
The best AI frame interpolation tools depend on your needs, but some highly recommended option is UniFab Smoother AI, which excels in generating smooth transitions between frames, improving the visual quality of videos with low frame rates.
Yes, frame interpolation increases the effective frames per second (FPS) by inserting additional frames between existing ones, making the video appear smoother. While the original video may have a lower FPS, interpolation creates the illusion of a higher frame rate, improving overall motion fluidity.
A video interpolator is a software or tool that inserts new frames between existing ones in a video sequence. By doing so, it smooths out motion, particularly in videos with lower frame rates, making them appear more fluid and less choppy. Video interpolators are commonly used for creating slow-motion effects or improving playback on high-refresh-rate displays.
The interpolation rate depends on the desired speed alteration; a 50% or higher rate typically maintains balance with a 1:1 interpolation rate.
