AI Music-Synced Marble Race Videos
Browser tool that analyzes a song's beats and sections, then renders a marble-race video synced to the music for TikTok and Instagram.
In plain English
RaceCut makes short marble-race videos that move in time with a song. You drop in a track and name your marbles, and the tool listens for the beat and the chorus. It then builds a race that lands on those moments and gives you a video ready for TikTok. Creators pay for it because these videos get lots of views.
