Speed up or slow down a video, then save the result as MP4. The tool runs directly inside your browser, so files are never uploaded to the website or stored on a server.
No software installation or account is required, and the tool works on both mobile and desktop.
Nujiz Change Video Speed lets you play footage slower or faster and export the adjusted result as a new file. Available speeds include 0.5×, 0.75×, 1.25×, 1.5× and 2×, with an option to keep audio when the browser supports it.
Slowing a video increases playback duration, while speeding it up reduces the duration. For example, 2× playback makes the clip faster and roughly halves its duration, while 0.5× makes it slower and increases playback time.
An option is available to keep audio during speed adjustment, but successful audio transfer depends on browser capabilities. Check the exported video if sound is important.
Moderate adjustments usually remain easier to watch, while large speed changes can make movement or speech less natural. Preview the result before publishing it.
The available choices are 0.5×, 0.75×, 1.25×, 1.5× and 2×.
The tool can attempt to keep audio when the browser supports it during export.
Yes. Faster playback shortens the duration and slower playback increases it.
The adjusted video is exported as MP4.
