What is Frame Interpolation
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.
Why Frame Rate Matters
Increasing a video's frame rate isn't just a technical upgrade—it directly impacts the quality of viewer experience. Here are key benefits of AI-powered frame rate interpolation:
- Removes Motion Jitter
Low-FPS videos can feel choppy, especially during fast movements. AI helps eliminate this jitter by generating interpolated video frames for smoother transitions.
- Improves Slow-Motion Effects
When slowing down footage, adding AI-generated frames keeps motion fluid instead of stuttering or tearing.
- Boosts Gaming Content
Many streamers and gamers use AI FPS increasers to upscale recorded footage for a more responsive and visually clean result.
- Restores Classic Footage
Vintage or archived videos shot at 24 or 30fps can be revitalized using interpolation software, making them compatible with modern high-refresh displays.
- Enhances VR & AR Experiences
Virtual and augmented reality applications require high frame rates (often 90fps or higher) to reduce motion sickness and improve realism—areas where AI frame rate increase plays a critical role.
How AI Video Frame Interpolation Works
Unlike traditional frame duplication—which leads to ghosting or static blur—AI frame interpolation software analyzes the actual motion patterns in a scene and predicts what the in-between frames should look like. Here's a simplified breakdown:
- Motion Analysis
The system uses AI to track motion vectors and identify moving objects across consecutive frames, such as faces, limbs, vehicles, or background pans.
- Smart Frame Synthesis
Instead of repeating or blending frames, the AI interpolation generates entirely new ones—known as interpolation frames—that accurately reflect natural motion.
- Adaptive Smoothing
Frame Interpolation AI applies context-aware smoothing techniques to balance motion sharpness and fluidity. This is especially helpful for interpolated video that includes action scenes or slow-motion.
- Real-Time Interpolation
Some advanced tools offer frame interpolation online or on-device in real time—perfect for live streams or game recording where low latency is crucial.
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.
