Frame Interpolation FAQ

What is frame interpolation?

Making new frames between existing ones. Instead of repeating or blending frames, the AI follows the motion between two frames and draws what lies halfway, so movement looks smoother.

How many frames are added?

One between every two frames: a clip with N frames comes back with 2N − 1 frames at twice the frame rate. The original frames are kept as they are.

Does it work on fast motion and scene cuts?

Smooth, steady motion works best. Very fast motion can show soft edges in the new frames, and at a hard cut the frame between two different shots is a mix of both.

Is it free and private?

Yes. No sign-up and no watermark, and it runs on your graphics chip in the browser, so your video stays on your device.
