How It Works

1

Choose a speed

Pick a preset between 0.5x and 2x, or use the Custom slider for any value from 0.25x to 4x.

2

Upload your video

MP4, MOV, MKV, or WebM up to 2GB. Drag and drop or click to browse.

3

Download the MP4

VidClean re-encodes with libx264 at CRF 23 and runs audio through the atempo filter, so pitch is preserved at any speed — no chipmunk effect.

Who uses this

Creators speeding up tutorials, time-lapsing screen recordings, or slowing footage down for a slow-mo effect. Editors prepping clips for social platforms that reward tight pacing. Anyone who needs a faster or slower MP4 without firing up a desktop editor.

Pick a speed, drop your video, get the new MP4 back.
