Change video speed
Speed up or slow down any video, from 0.5x to 3x, with control over what happens to the pitch.
Voices keep a natural pitch, no chipmunk/slow-motion effect.

How it works
Drop a video in and pick a speed from 0.5x to 3x.
Choose whether voices should keep a natural pitch, or shift with the speed (like a sped-up/slowed-down record).
Download the re-timed video — audio and video stay in sync.
When you'd use this
- You have a long screen recording or tutorial and want to speed it up for a punchier final edit.
- You want a dramatic slow-motion effect on a highlight clip.
- You recorded footage at the wrong frame rate and need to re-time it to play back correctly.
Frequently asked questions
What's the difference between the two pitch modes?
"Keep pitch natural" time-stretches the audio so voices sound normal at any speed. "Let pitch shift" instead resamples the audio, so pitch rises with faster speeds and drops with slower ones — like literally speeding up or slowing down a recording.
What's the speed range?
0.5x (half speed) up to 3x (triple speed), adjustable with presets or a custom slider.
Does the video stay in sync with the audio?
Yes — both are re-timed together by the same factor.
Can I use this for slow-motion effects?
It re-times existing footage rather than generating new in-between frames, so smoothness at slow speeds depends on your source frame rate — footage shot at a high frame rate will look smoother slowed down than footage shot at a standard rate.
Which pitch mode should I use for a screen recording tutorial?
Keep pitch natural — sped-up narration with shifted pitch sounds cartoonish and is harder to follow, while natural pitch keeps the voice sounding normal even at 2x speed.
