2025 Best AI Frame Interpolation Software for Smoother Video

Modern audiences expect buttery-smooth videos—whether watching slow-motion sports replays, cinematic scenes, or 4K animations. However, many videos are recorded at standard frame rates like 24 fps or 30 fps, leading to choppy motion or limited flexibility in post-production.

That’s where AI frame interpolation software comes in. These intelligent tools can generate intermediate frames between existing ones, effectively increasing the frame rate to 60 fps, 120 fps, or even higher—resulting in ultra-fluid, lifelike video playback.

Part 1. What is AI Video Frame Interpolation

Before starting to realize AI Video Frame Interpolation, let's learn about some basic knowledge of the frame.

1. What Is Frames Per Second?

Frames per second" (FPS) is a measurement used to describe the frame rate or the number of frames (images) displayed or processed per second in a video, animation or game. It indicates the smoothness of motion in a video or game. the higher the FPS value, the smoother and more realistic the motion usually is.

2. What Is AI Video Frame Interpolation?

Frame interpolation is the process of generating additional frames between existing ones to make motion smoother. Traditionally, this is done through optical flow and motion vector estimation. However, traditional interpolation often fails to accurately predict object motion, especially when there’s:

• Rapid camera movement
• Fast-changing scenes
• Occlusion (objects moving in and out of frame)
• Complex textures and lighting changes

Traditional methods can cause issues like ghosting, motion blur, or tearing—problems that make videos look unnatural. By contrast, AI video frame interpolation uses deep learning algorithms trained on thousands of motion sequences. These AI models understand object depth, motion trajectories, and scene composition, allowing them to create realistic intermediate frames.

3. What’s the Role of 2X/4X Frame Interpolation?

Coming to AI video frame interpolation, this task needs to be completed with AI-powered tools. Even beginners can interpolate their videos using AI.
