Speeding up without the chipmunk voice
Playing a recording faster the naive way raises every voice in it, because the sound waves are squeezed along with the picture. The export here changes the tempo of the audio and leaves its pitch alone, so speech at 1.25x or 1.5x still sounds like the same person, just brisk.
That is what makes speeding up useful for talking-head videos, demos and lectures: most viewers can follow speech comfortably at 1.25x to 1.5x, and it trims the running time by a fifth to a third without cutting a word.
Slow motion that looks smooth
Slowing a clip down stretches the frames it already has. Footage shot at 60 frames a second or more slows to half speed cleanly, because there are enough real frames to fill the time; a 30fps clip slowed to 0.5x holds each frame for twice as long, so fast movement can look slightly steppy.
For the smoothest slow motion, record at the highest frame rate your phone or camera offers, then slow it here.

| Speed | A 60s clip becomes | Good for |
|---|---|---|
| 0.5x | 120s | Slow motion, sport, a moment worth watching twice |
| 1.25x | 48s | Talking heads, lectures, a tighter demo |
| 1.5x | 40s | Tutorials people already skim at 1.5x |
| 2x | 30s | Screen recordings with slow stretches |
| 3x | 20s | A time-lapse feel for long, steady footage |
Questions about change video speed
Does the voice sound like a chipmunk when I speed it up?
No. The sound is sped up with its pitch kept, so a 1.5x voice sounds like somebody talking quickly rather than somebody on helium. Past 2x it gets hard to follow, which is why the fastest choice is 3x.
How long will the new video be?
The original length divided by the speed: a 60-second clip at 2x lasts 30 seconds, and at 0.5x it lasts two minutes. The panel shows the result before you export.
Is it free?
Yes. Change the speed and preview free, and a free account downloads the result. Free exports and share pages include a small REQO badge. Go Pro to remove it.
