Change video speed

Upload a video and play it at 0.5×, 2×, 3× or 4× speed. The audio is speed-matched at the correct pitch, and the original resolution and quality are kept.

Will the audio sound like a chipmunk?

No — the audio is time-stretched with pitch correction, so voices stay natural. At 0.5× the sound plays slower, at 2–4× faster, always in sync with the video.

Why can't I speed up a very short clip?

At 4× a clip shorter than 4 seconds would end up under one second long, which players handle poorly. If you see the "too short" warning, pick a slower speed.
