Frame Interpolation Explained: What It Is & How to Do It

Have you ever watched a video and wished it looked smoother? Or tried creating a slow-motion effect but ended up with choppy footage? This is where frame interpolation comes in. Frame interpolation is a technique used to generate extra frames between existing ones, making videos appear smoother and more fluid.

Whether you're a filmmaker, content creator, or just someone looking to enhance video quality, frame interpolation can be a game-changer. In this article, we’ll explain what frame interpolation is, how it works, its applications, and how you can use it—especially with Cyberlink's PowerDirector.

What Is Frame Interpolation?

Frame interpolation is a video processing technique that inserts artificially generated frames between existing frames to create higher frame rates and smoother motion.

This technique is commonly used to:

✅ Convert low frame rate videos (24fps or 30fps) to higher frame rates (60fps or more).

✅ Create slow-motion effects without needing high-speed cameras.

✅ Improve video playback smoothness, especially for gaming, sports, and action footage.

How Does Frame Interpolation Work?

Frame interpolation relies on motion estimation algorithms to analyze movement in a video and predict missing frames. There are three main methods used:

1. Motion Compensation Interpolation

• Analyzes object movement between frames.
• Creates new frames by shifting pixels to where they should be.
• Provides realistic motion but may struggle with complex scenes.

2. Frame Blending Interpolation

• Overlaps adjacent frames to generate a smoother transition.
• Easier to process but can cause ghosting effects.

3. AI-Based Frame Interpolation (Most Advanced)

• Uses artificial intelligence to accurately predict motion and generate high-quality frames.
• Handles complex movement better than traditional techniques.
• Found in premium software like CyberLink PowerDirector and Topaz Video AI.

4. Next click "Edit". Under the "Video" category, go to the "Enhance" subcategory and click on "AI Video Enhancement".

   

5. On the pop up dialogue box, make sure "Frame Interpolation" box is checked. Finally, click "Enhance".

   

6. It may take a few minutes for your video to be generated. Once prompted, click the profile icon on the upper right corner of the top navigation bar. Go to "My GenAI Creations" and navigate to "AI Video Enhancement".

   

7. Once you locate your video you may add it to timeline or export it.

   

Other Software for Frame Interpolation

If you're exploring alternatives, here are some other options:

• Adobe After Effects – Uses Pixel Motion for interpolation but requires manual setup.
• Topaz Video AI – Advanced AI-driven interpolation but comes with a high price tag.
• SVP (SmoothVideo Project) – Best for real-time frame interpolation in video playback.

While these tools work well, PowerDirector stands out for its balance of AI precision, ease of use, and affordability.

Conclusion

Frame interpolation is a powerful technique that can elevate your video quality, whether you’re creating smooth slow-motion shots, enhancing old footage, or improving playback.
