Slow a jump, splash or goal down to 0.5× to show every detail.

Speed up cooking, drawing or building videos 4× to fit a Reel.

Faster tutorials

Tips for the best result

  • Slow motion looks smoothest from 60 fps footage.
  • Combine 1.5–2× speed with Boomerang for the snappy Instagram look.
  • "Keep voice natural" uses pitch-preserving stretching, so speech stays clear at any speed.

Change speed — FAQ

Does the audio sound weird when sped up?

No — "Keep voice pitch" time-stretches the audio so it stays natural. Turn it off for the classic chipmunk effect.

Does slow motion add frames?

No — frames are shown longer rather than invented, so 30 fps footage slowed to 0.25× will look choppy.

Can I speed up just one part?

The speed applies to the whole video. Trim first to keep only the part you want to change.

What happens to the sound?

It changes speed with the video. With "Keep voice natural" on, the pitch stays the same.
