Change Video Speed

Make a long video quicker to watch, create a time-lapse effect or slow down an important moment. Choose a speed from 0.25× to 4×; the sound is adjusted too and keeps its natural pitch, so voices do not sound like cartoons.

How to change the speed of a video

1. Upload your video.
2. Choose a speed, for example 2× or 0.5×, and whether to keep the sound.
3. Click Convert and download the new video.

Video speed changer features

• Eight speeds from 0.25× (slow motion) to 4× (fast forward).
• Natural-sounding audio at every speed, or no sound.
• Keeps the original format and resolution.

Tips for slow motion

Slow motion looks smoothest when the original was filmed at a high frame rate, such as the 120 or 240 fps slow-motion mode of many phones. Normal 30 fps videos slowed to 0.25× show each frame longer.

Frequently asked questions

Will the voices sound high or low?

No. The pitch is preserved; only the tempo changes.

How long can the result be?

Up to 60 minutes, so slowing down a long video may not be possible.

Can I remove the sound?

Yes. Choose Remove the sound, which is useful for time-lapses.
