Ever wondered how your favorite YouTubers get their videos to look so incredibly smooth? Or why do the latest blockbuster movies have that crystal-clear, fluid motion? The secret recipe often lies in something called AI frame interpolation. It's a bit of tech magic that's changing the game for video quality everywhere, from personal vlogs to professional films.
In this article, we're going to dive into what AI frame interpolation is and provide the top picks of the tools for this need.
In this article
Part 1. The Purpose of Frame Interpolation
Frame interpolation makes videos smoother by adding extra frames between the existing ones. This helps reduce jerkiness, motion blur, and stuttering, especially in fast-paced or slow-motion videos, giving you a much better viewing experience.
AI Video Frame Interpolation uses advanced tech to smooth out videos. Normally, videos can look choppy if they don't have enough frames per second. This AI-driven technique fixes that by creating new frames, making the video appear much smoother.
Here's how it works: First, the AI looks at how pixels move between frames to understand the movement of objects in the scene. Then, it uses this info to shift pixels around and create new frames that fit perfectly between the original ones. This makes the video flow better without speeding it up.
When choosing AI Video Frame Interpolation, look for accuracy because exact algorithms make frames look natural. Real-time processing is also important, especially for live streaming and gaming where smooth motion is key. The best AI should reduce errors, avoid strange visual effects, and work well without needing a lot of computing power. In short, AI Video Frame Interpolation makes videos smoother and more enjoyable by adding new frames where needed.
Part 2. Top 5 AI Frame Interpolation Tools [Free and Paid]
Now that we understand the concept behind AI frame interpolation and its benefits, let's look at the best tools available to help you achieve these smooth and professional-looking videos. Whether you're a beginner or a seasoned pro, these top 5 AI frame interpolation tools offer a range of features to fit your needs.

How to Use Filmora AI Interpolation
Here's a quick guide on how to use Wondershare Filmora's AI Frame Interpolation to enhance your videos.
Step1Import the Clip and Drop It into the Timeline
First, import your video from your PC's File Explorer. Drag and drop the video onto the timeline using your cursor. This is where you'll start editing.
Step2Activate the AI Frame Interpolation
Next, activate the AI Frame Interpolation feature. Go to the "Speed" tab and choose "Uniform Speed." Then, expand the AI Frame Interpolation section and select "Optical Flow" from the available options if you want to get a higher quality result.
Step3Render Preview or Export for Results
To see how your changes look, you can use the Render Preview to give you a quick look at the results. If you're happy with it, you can go ahead and export your video to finalize the outcome.
2. Runway
Runway Frame Interpolation is an online tool designed to transform a sequence of images into a smoother, more fluid video. So, unlike other AI video interpolation tools, Runway works by generating intermediate frames between your existing images. After uploading your image sequence, you can set the clip duration, and Runway will automatically generate and insert the new frames to create a continuous video.
Key Features
- AI Interpolation: This tool uses AI to insert extra frames between image sequences to make a smooth videos
- Adjustable Clip Duration: You can adjust the overall length of the clip, and Runway will automatically recalculate and generate the necessary intermediate frames.
3. Hitpaw Video Enhancer
HitPaw Video Enhancer is a fantastic frame interpolation tool for boosting the quality of your videos. Using advanced AI, it fixes glitches, removes artifacts, and upscales your videos to 4K or even 8K, making your old or low-quality videos look stunningly smooth.
Key Features
- Customizable AI Frame Interpolation: HitPaw's frame interpolation AIlets users choose between 2X or 4X interpolation, giving them the flexibility to adjust the frame rate according to different needs.
- AI Video Repair: You can use this AI feature to fix glitches and artifacts from your videos before the interpolation process
- Sharpen Video: Recognizes textures and grains to automatically remove motion blurs and out-of-focus areas to enhance your video further.
4. Flowframes
Flowframes is a powerful yet easy-to-use desktop app that leverages advanced AI to interpolate videos, boosting their frame rates in a natural-looking way. This AI interpolation is free, and great for anyone wanting to enhance their videos, making them smoother and more fluid.
