Beat Sync

Photo + song = music video

Upload a photo and an audio track (or let AI generate music from a text description). The AI creates a beat-synced video with motion cuts matched to the BPM of the music.

How Beat Sync Works

Beat Sync analyzes your audio track to detect BPM, beat positions, and energy curves, then generates video clips with motion cuts timed to the rhythm. If you do not have an audio track, you can describe the music you want (genre, mood, tempo) and the AI generates both the music and the synced visuals in one pass. Musicians use Beat Sync for quick promotional content -- turn album art into an animated music video without hiring a video editor. Fitness instructors sync workout highlight photos to energetic tracks. Event promoters create beat-matched recap videos. Social media creators produce rhythm-driven content that algorithms favor because viewers watch longer. For the best results with uploaded audio, use tracks with a clear beat -- electronic, pop, hip-hop, and rock work best. Ambient or classical tracks with irregular timing produce less dramatic visual cuts. The source photo should have enough visual detail to generate interesting motion. Landscapes, cityscapes, and action shots produce more dynamic results than simple portraits.
