What problem does it solve? Turning a music track into a beat-synced video normally requires manual timeline editing, beat detection, and frame-by-frame motion design. This Skill automates that pipeline: it analyzes the audio once, plans frames against the beat grid, builds each frame as an HTML composition, and renders a final MP4. ## Core Features & Use Cases - Deterministic audio analysis: A single analyzer script produces an audiomap.json with BPM, beat grid, drum events, rolls, energy phases, and key moments that drive all visual timing. - Orchestrated multi-step workflow: Six gated steps cover setup, analysis, frame skeleton, user-approved planning, parallel per-frame sub-agent builds, assembly, and verified rendering. - Template and motion-primitive catalogs: Frames are filled from a catalog of beat-synced typography templates or free-composed motion primitives, with optional user images/videos cut in via beat-cut or ken-burns treatments. - Use Case: Give the Skill a synthwave track and ask for a 30-second promo video; it analyzes the beat grid, plans frames around drops and rolls, builds kinetic typography compositions, and renders a beat-synced MP4. ## Quick Start Use the music-to-video skill to turn my track bgm.mp3 into a beat-synced 1920x1080 video and render it to an MP4.
