Machine learning analyzes your track and maps beats across the timeline. Downbeats, strong hits, medium, weak. All color-coded. Drag them, delete them, add your own manual beats. Use them to auto cut video to music or place each edit by hand. The AI gives you the map. You decide what to do with it.
