The same clip playing in slow motion, natural speed, and timelapse

How it works

1

Upload your video

Any MP4, MOV, or WebM. Continuous motion or talking footage both work.

2

Pick the speed

Slow it to 0.5x, tighten it to 1.5x, double it, or compress it 4x into a timelapse.

3

Download the retimed clip

Video and audio stay in sync at the new pace, with the audio pitch corrected to sound natural.

What this blueprint does

Speed is the most underrated edit there is. The same footage reads dreamy at half speed, efficient at 1.5x, and hypnotic as a timelapse. The catch has always been the audio: naive speed changes shift the pitch, so voices turn into chipmunks or slide into slow-motion growls. This blueprint changes the video speed and corrects the audio tempo in the same pass, so a 2x clip sounds like someone talking quickly, not someone breathing helium.

What you get

Your clip retimed to the speed you chose, with pitch-corrected audio that stays in sync, exported as a platform-ready MP4.

Who uses it

Tutorial and process creators

Keep the talking parts natural and compress the repetitive stretches to 2x or 4x.

Sports and action editors

Drop the key moment to half speed so the impact actually registers.

Makers and artists

Turn an hour of painting, cooking, or building into a feed-ready timelapse.

Frequently asked questions

Will voices sound weird?

No. The audio tempo is corrected in the same pass, so speech keeps its natural pitch at every speed. A 2x voice sounds fast, not squeaky.

What happens to the video length?

It scales with the speed: 0.5x doubles the duration, 2x halves it, 4x quarters it. Compute minutes are billed on the processing, not the output length.

Can I speed up a video that has no audio?

Yes. Silent clips retime exactly the same way; there is just no audio track to correct.

What does it cost?

Speed Changer runs on your plan compute minutes like any transcode. The free tier includes 100 minutes a month, no credit card required.
