Smooth Slowmo: Slow Motion

Real optical-flow slow motion, now on speed ramps too. Shape a curve, tap Smooth, export in 4K. First smooth export free — Pro is a one-time purchase.

Turn any clip into cinematic slow motion — with real in-between frames, not the juddery frame-duplication every other editor gives you.

SMOOTH SLOW MOTION, DONE PROPERLY Most apps slow video down by repeating frames. Smooth Slowmo generates brand-new frames between the real ones using optical flow, so even a 0.2× shot stays fluid instead of stuttering.

SPEED, YOUR WAY • Normal — dial any constant speed from 0.1× to 10× on a precision ruler • Curve — drop beats on a timeline and shape a ramp that slows down and speeds back up exactly where you want it • Smooth follows the whole curve, not just the slowest point

A REAL EDITOR, NOT A FILTER • Trim first, so you only work the part that matters • Live preview with scrub, loop and a full-screen player • Mute the audio, or let the pitch drop with the speed • Export at 720p, 1080p, 4K or original quality • Saves straight to Photos — no watermark, ever

FREE AND PRO Everything in the editor is free: every speed, every curve, every resolution, and nothing stamped across your footage.

Your first smooth slow-motion export is free as well. After that, unlimited smooth exports are a one-time purchase — no subscription, nothing to cancel.

HOW IT WORKS

1. Pick a clip and trim it
2. Choose a speed, or shape a ramp with beats
3. Tap Smooth, then export
