What is Frame Interpolation
Smooth motion is crucial for delivering clear, engaging video content. Frame interpolation is a technique that inserts additional frames between existing ones to enhance motion fluidity, especially in videos with low frame rates. This process helps eliminate choppiness, making videos appear smoother and more visually appealing.
Various frame interpolation software programs are available, each offering different features and performance levels. Whether for casual video enhancement or professional post-production, these tools help improve playback quality, particularly for videos with frame rates of 30fps or lower.
Understanding AI Video Frame Interpolation
AI-driven frame interpolation takes this process a step further by using artificial intelligence to intelligently generate intermediate frames. This significantly reduces motion blur and jerkiness, producing a seamless, high-quality output ideal for slow-motion effects and improving older or low-frame-rate videos.
AI video frame interpolation is widely used for animation smoothing, old movie restoration, and optimizing video playback for high-refresh-rate screens. By leveraging machine learning algorithms and deep neural networks, these tools make frame interpolation more accessible, efficient, and precise, even for beginners.
To help users find the best solutions, we’ve curated a list of the 12 best AI frame interpolation tools available for Windows, Mac, and online platforms.

FAQs about AI Interpolation
What is the best frame interpolation AI?
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.
Does frame interpolation increase FPS?
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.
What is a video interpolator?
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.
What is the recommended time interpolation rate for smooth playback?
The interpolation rate depends on the desired speed alteration; a 50% or higher rate typically maintains balance with a 1:1 interpolation rate.
