1. 1. Load your ride video

    Any stretch of trot will do. It plays here and never leaves this device.

  2. 2. Choose one song

    A track you own, as MP3, M4A, WAV or FLAC.

What happens

  1. Your taps become a tempo. Tap each time a front foot lands, at least 8 times. The median gap between taps gives the beats per minute.
  2. The song is stretched. Faster or slower to match, by a time stretch that keeps the pitch, so a singer does not turn into a chipmunk.
  3. It plays in sync. The music is scheduled on the audio clock and the video is held to it.

Nothing on this page is saved. The whole freestyle, every gait, crossfades, the time check and the exports, is in the builder; the rules are on how the tempo and the stretch work.
