Change video playback speed.
Video Speed Changer makes a video faster or slower, from 0.25x (slow motion) to 4x (time-lapse), with presets for the common speeds. The sound is sped up or slowed down too while keeping its pitch natural. The new MP4 is created in your browser and shows its new length before you start.
Made for creators. Typical uses:
Speeds are limited to 0.25x to 4x. Slowing a video down cannot add detail, so slow motion from normal footage looks stepped unless the original has a high frame rate. Files over 500 MB are refused.
Accuracy: Video is processed with the open-source ffmpeg engine running in your browser and tested with sample clips. Check the result before you share it.
