A different pace for every clip.

Add up to 10 clips. Your selected speed is applied to each separately.

01 / TIMING

A precise multiplier

Choose a common speed or enter a custom value. A 10-second clip becomes roughly 5 seconds at 2×, or 20 seconds at 0.5×.

02 / SOUND

Choose how it sounds

Pitch-preserving audio helps speech stay natural. Speed-shifted pitch creates the classic fast or slow recording effect. Silent videos remain silent.

03 / PRIVACY

On your device

Original recordings are not uploaded or modified. Export and preview a new MP4, with progress and cancellation available throughout.

Slow motion, audio and limitations

The selected speed applies to the whole video. Slow playback repeats source frames to maintain a usable frame rate; it does not invent missing motion or use AI frame interpolation. Output frame rate follows the source up to 60 fps. Sound is retimed to match; pitch preservation can introduce artifacts at extreme speeds.

Export uses H.264 / AAC MP4, with even display dimensions and the first audio track unless removed. Encoder padding and video frame precision can slightly affect duration. Extra tracks, subtitles, descriptive tags, attachments and chapters are omitted.

Choose up to 10 files, each up to 512 MiB. Many common formats work; encrypted, corrupt, HDR and unsupported codecs are rejected. The engine downloads about 31 MiB on first use. Slow-motion exports are longer and can use considerable memory. Keep this page open while exporting.
