Change Video Speed

Speed up or slow down a video — from 0.25× to 4× speed.

Upload a video and choose a playback speed multiplier. Audio pitch is adjusted automatically.

Speed changes are one of the most popular creative video effects. Slow motion makes action sequences more dramatic; fast-forward compresses long time-lapses into brief clips. Our tool handles both directions across a wide range.

Audio pitch correction is applied automatically using the atempo filter, which maintains a natural-sounding voice or music track at the new speed. Without this, sped-up voices would sound chipmunk-like; slowed-down audio would sound unnatural.

For speeds outside the 0.5× to 2× range, ffmpeg requires chaining multiple atempo filters. Our backend handles this automatically — you can choose any speed from 0.25× to 4× and the audio remains properly pitched.
