AI Slow Motion Video FAQ

What is AI slow motion?

Instead of repeating frames, an AI model draws new frames between the real ones, so a clip can play several times slower and still move smoothly, like footage from a high-speed camera.

How slow can it go?

2×, 4× or 8× slower. At 8× the AI draws 7 new frames between every two, so a 30 fps clip becomes an effective 240 fps moment.

Does it work on any video?

It works on MP4, MOV, WebM and MKV clips up to 60 seconds. Steady shots with a clear subject give the cleanest in-between frames.

Is it free and private?

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