I tested this AI video smoother with 30fps sports footage, and the conversion to 60fps was smooth. The AI-generated frames significantly improved motion fluidity with minimal jitter or artifacts, which is often seen in other software. The GPU acceleration also boosted the processing speed impressively. That is a perfect video fps increaser！
UniFab is an AI video smoother that reliably converts older travel footage to 60 fps with clean, cinematic motion. Its consistency and detail preservation outperform most consumer solutions I've evaluated.

An AI video smoother increases a video's frame rate by creating additional frames, making motion appear smoother. UniFab Smoother AI can use frame interpolation to convert ordinary footage to 60 FPS for smoother playback.
An AI frame interpolation tool creates new frames between existing ones to increase video FPS and smooth motion. For example, UniFab Smoother AI can convert 60 FPS video to 120 FPS by filling gaps between frames.
AI frame interpolation creates new intermediate frames for smoother, more natural motion. Traditional speed adjustment only changes playback speed without increasing frames, often causing choppy or unnatural video.
For frame interpolation, we recommend
Windows 11 or Windows 10 (64-bit only),
16 GB or more of system memory,
an NVIDIA RTX 30 Series or newer graphics card with 8 GB VRAM, and an Intel Core i7 8th Generation or AMD Ryzen 3000 Series or newer CPU.
Tested ranking of 12 FPS converter tools across browser, desktop, and use case. Includes a real 30 → 60 fps and 60 → 120 fps test showing what AI frame interpolation actually produces vs. simple frame duplication.
A practical 2026 guide to 60 FPS vs 120 FPS for video and gaming. Covers definitions, input-lag math, monitor and HDMI requirements, when 120 FPS is worth it (and when 60 FPS is enough), the top tools for converting 60 FPS footage to true 120 FPS with AI frame interpolation, and a step-by-step UniFab Smoother AI walkthrough.
The best 60 fps converter for most users in 2026 is UniFab Smoother AI. In our hands-on tests on an RTX 4070, it produced the cleanest AI-interpolated frames on fast basketball footage and completed a 1-minute 1080p clip in under 3 minutes with no watermark during its 30-day trial. Topaz Video AI and HitPaw are strong alternatives; Veed.io and Media.io are convenient but cut corners on real interpolation.
