How to change the speed of a video

  1. Choose your video.
  2. Pick a speed from 0.25× to 4× (or type your own) and what happens to the sound.
  3. Press the button and download the video.

The sound

  • Keep the normal pitch: voices stay natural at any speed (the sound is time-stretched).
  • Higher or lower with the speed: like playing a tape faster or slower.
  • Remove the sound: for silent time-lapses.

Good to know

  • Slow motion shows each frame longer; it doesn't invent frames in between, so very slow speeds can look choppy.
  • Fast videos are kept at no more than 60 frames per second, so they play smoothly everywhere.
  • It uses your browser's built-in video technology: best in current Chrome and Edge, and recent Safari and Firefox versions.

常见问题

Can I speed up only part of a video?

Not in one step. Cut the part out with the Video Cutter, change its speed here, and join the parts with Merge Videos.

Is my video uploaded?

No. It is processed in your browser and never sent anywhere.
