What people use it for

Change the speed of your video right in the browser, with no upload. Here are the common reasons people speed up or slow down a clip.

Speed up a how-to

Take a long screen recording or tutorial and run it at 2x so viewers get to the point. The same trick turns a slow phone clip of a sunset or a build into a quick timelapse.

Slow-motion review

Drop a clip to 0.25x to study a golf swing, a soccer goal, or a kid's first steps frame by frame. Great for sports footage where the action is over in a second.

Fit a target length

Nudge the speed up or down to land a video under a hard limit, like a 60 second Reel or a Shorts cut, without cutting out the parts you want to keep.

Trim under a size cap

Speeding a clip up makes it shorter and smaller, which helps it slip under Discord's 10 MB or WhatsApp's 16 MB sharing limit so it sends on the first try.

Skip the slow parts

Fast-forward the dead time in a long OBS WebM stream recording or an iPhone MOV of a meeting, so the boring stretches go by in seconds and the good bits stay watchable.

Study a detail

Slow footage to half speed to read a fast caption, catch a magic trick, or follow a recipe step that flew by the first time.

Frequently asked questions

Yes. Audio is time stretched to match so voices still sound natural.
