Slow motion video editor
FrameOS includes speed controls in the timeline editor. Slow down any segment of a clip to 50%, 25%, or a custom frame rate — useful for reaction moments, action highlights, and dramatic pauses that land better at reduced speed.
Speed controls in the timeline editor
The FrameOS timeline editor includes a speed control for every clip segment. Select the section you want to slow down, choose a playback rate, and preview the result before committing to an export. You can slow a single moment — a reaction, a key phrase, a highlight — while the rest of the clip plays at normal speed.
Why slow motion works on short-form
A one-second moment in real time often isn't long enough to register in a fast-scrolling feed. Slowing it down creates a beat that viewers can feel. Reaction shots, surprise moments, and physical demonstrations are the most common slow-motion candidates in short-form content because they reward the viewer for paying attention — the slow-down signals that something notable just happened.
Export slow-motion clips for every vertical platform
Slow motion clips export in the same vertical 9:16 format as all FrameOS outputs — ready for YouTube Shorts, Instagram Reels, TikTok, LinkedIn, and X. Captions stay timed to the slowed audio if you keep the audio track, or can be retimed if the audio is removed.

FAQ
How do I make a video slow motion in FrameOS?
Select the segment in the timeline editor, open speed controls, and choose a reduced playback rate. Preview the result and export when it looks right.
Can I slow down just one part of a clip?
Yes. Speed controls apply per segment, so you can slow a single moment while the rest of the clip plays at normal speed.
What's the minimum playback speed?
FrameOS supports slow-motion down to 25% (quarter speed) and custom frame rate reductions. Extreme slow-down from footage without enough source frames will produce motion blur.
