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

Aspect	2X Interpolation	4X Interpolation
Principle	Inserts 1 AI-generated frame between original frames (doubles FPS)	Inserts 3 AI-generated frames (quadruples FPS)
Performance Boost	2.6-3.9× FPS increase	4.9-10× FPS increase
Resolution Support	Optimized for 4K	Enhanced 4K/8K performance
Visual Quality	Potential minor blurring	Sharper textures
Use Cases	Basic ray tracing, video frame interpolation	High-refresh gaming, cinematic slow-mo

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