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, cuts the track into frames at real musical changes, plans a per-frame treatment, and builds each frame as an HTML composition rendered to MP4. ## Core Features & Use Cases - Deterministic audio analysis: A single analyzer script produces an audiomap.json with beat grid, onsets, drum classification, energy phases, rolls, silences, and key moments that drives all timing decisions. - Orchestrated multi-step workflow: Setup, analysis, frame skeleton, user-approved plan, parallel per-frame sub-agent builds, deterministic assembly, and lint/validate/inspect verification before rendering. - Template and motion-primitive catalogs: Typography-first templates and free-compose motion primitives mean a complete video needs zero user assets; supplied images or videos are cut in on the same beat grid via beat-cut, ken-burns, or background treatments. - Use Case: Give the Skill a 30-second synthwave track and a short tagline; it produces a beat-synced kinetic typography video rendered to renders/video.mp4 at 1920x1080. ## Quick Start Use the music-to-video skill to turn my track bgm.mp3 into a beat-synced kinetic typography video with the tagline "Ship It".
