How to speed up a video

Drop the video

MP4, MOV, WebM, and AVI all work. The file stays in the browser.

Leave it at 2×, or go faster

2× is selected. Use 4× or higher when the recording has long pauses. Press play to judge the pace.

Download the MP4

Keep the pitch for a voiceover, or mute the track for a silent time-lapse. Then export.

When speeding a video up helps

Tutorials with dead time

A 2× export keeps the clicks and the explanation while cutting the watch time in half.

Long screen recordings

Setup, loading, and scrolling compress into a demo someone will actually finish.

Shorts and Reels

4× or faster turns a long take into a short clip without cutting each pause by hand.

A silent time-lapse

Mute the audio and push the speed up when the picture is the point and the room noise is not.

Frequently Asked Questions

How do I speed up a video online?

Drop the file in. 2× is already selected, which cuts the runtime in half. Press play to preview, then click Change speed and download the MP4. The slider goes up to 16×.

What happens to the voice?

Keep pitch speeds the picture up and leaves a narration sounding natural. Shift pitch raises the voice with the speed. Mute drops the audio, which suits a fast time-lapse.

Can I slow a video down instead?

Yes. Slow Down Video opens at 0.5×. Use that when you want the clip longer, not shorter.

Is the video uploaded?

No. FFmpeg runs in your browser. The file stays on your device.
