Why change a video's speed?
Speeding up a screen recording or a long clip keeps the viewer's attention, while slowing one down can emphasize an action or make a fast-motion moment easier to follow. This tool changes the speed of both the picture and the sound together, so they stay perfectly in sync.
Unlike simply changing playback speed in a video player, this re-encodes the file itself — the result plays at the new speed everywhere, including once it's downloaded, shared or reposted.
Frequently asked questions
Does the audio stay in sync with the video?
Yes, both the picture and the sound are sped up or slowed down by the same amount, so they stay in sync.
Does this affect the audio pitch?
No, the pitch stays natural — only the speed changes, the same way the change audio speed tool works for audio-only files.
