What you can do.Without leaving the project.

  1. Score the edit

    Describe the mood and length; the track lands under the video and ducks when someone speaks.

  2. Cut on the beat

    JsonCut finds the beat grid of the music and snaps cuts and motion to it.

  3. Place sounds where things happen

    Library sounds and generated effects line up with the moment on screen, not a few frames off.

Where it is used.Real projects, open them in Studio.

Reels that sound finished

Two raw clips became a reel with music, sound effects and punch-ins on the beat.

Cuts on a beat grid

A brief is typed, eight clips are scanned and three winners take the stage, all on a 120 BPM grid.
