AI frame interpolation · speed ramps
Slow motion from any video.
Shot at 24 or 30 fps? Mark the moments you want slowed on a timeline. Slowify invents the in-between frames with optical-flow AI and eases smoothly in and out of each slow section.
Works on your phone. Videos up to 5 minutes, rendered at up to 1080p.
Upload
Straight from your camera roll or desktop. The upload goes directly to private storage.
Mark
Drop slow-mo sections on the timeline, pick a speed from 75% down to 5%, and set how gently it ramps.
Render
A GPU generates every missing frame (RIFE v4.25) and retimes the audio. Download an MP4 a few minutes later.
Good to know
Will it look like a real high-speed camera?
Close, for most footage. Frames shot at a normal shutter speed already contain motion blur, so very fast action can look softer than true high-speed footage. Fast spinning wheels, thin objects and hands crossing can warp a little.
What happens to the sound?
By default the slowed parts are time-stretched without changing pitch. You can also mute the slowed parts, or drop the audio.
Scene cuts?
Slowify detects cuts and never blends across them.
How long are files kept?
Uploads and renders are deleted automatically after 30 days. You can delete them sooner.
