About Change Video Speed
Change the playback speed of any video from 0.25x (slow motion) to 4x (fast forward), entirely in your browser. Both the video and audio are adjusted together –audio pitch is corrected automatically so voices sound natural at any speed. This tool is perfect for creating time-lapse effects, slow-motion replays, speeding up tutorials, or adjusting presentation pace. Supports MP4, WebM, MOV, AVI, and MKV formats. Uses FFmpeg for local processing –your videos stay on your device.
Frequently Asked Questions
Does the audio change speed too?
Yes. Audio speed is adjusted to match the video speed, with pitch correction so voices sound natural.
What speed is good for time-lapse?
4x for short time-lapse effects. For longer time-lapses, consider extracting frames instead.
Can I create slow motion?
Yes. Set speed to 0.25x or 0.5x. Note that true slow motion requires high-FPS source footage for smooth results.
