Smooth slow motion

Make real slow motion without stutter: the AI (RIFE) invents the in-between frames, ×2 or ×4, or turns your video into 60 frames per second. Slowed sound without distorted voices. Free, no watermark.

Accepted: MP4, MOV, M4V, WEBM, MKV · Max 95 MB per file

Video sent to the server for processing, deleted right away.

How to make smooth slow motion

  1. Drop your video (60 seconds max, 95 MB max).

  2. Pick slow motion ×2, ×4 or “smoother”, then click “Create the video”.

  3. Watch the result and download it (MP4).

Why here

AI in-between frames
RIFE invents the missing frames between two real ones: smooth slow motion, without the stutter of a plain slowdown.
Sound slowed cleanly
The sound is stretched without changing voice pitch, or removed if you prefer.
Fast
A few seconds of processing for a few seconds of video; the page shows the time left.
Nothing is kept
The video is deleted once processed, the result after you download it.

Frequently asked questions

How do I make smooth slow motion without stutter?

A plain slowdown repeats the same frames, hence the stutter. Here, RIFE, an open AI, creates real in-between frames between two frames of the video: at ×2, one invented frame per pair; at ×4, three. Motion stays continuous.

What's the difference between slow motion and “smoother”?

Slow motion makes the video longer (×2 or ×4) at the same frame rate. “Smoother” keeps the same length but doubles the frames per second (30 → 60 fps), for softer motion on recent screens.

What about the sound?

In slow motion, the sound is stretched without changing voice pitch; you can also remove it. In “smoother” mode it stays the same.

Are there artefacts?

On very fast motion, thin objects (propellers, hair in the wind) or scene cuts, invented frames may show slight blur or warping. That's the limit of every interpolation method, paid ones included.

Is my video kept?

No. It's sent to our server, processed, then deleted; the result is removed after you download it.
