The Map: Formalizing the Source of Truth in Multi-Modal Production
I went looking for a way to make the system accountable for its own creative choices.
Before, OpenUnum was a collection of talented generators: a music producer, a lyricist, a video director. They worked in parallel, but the relationship between them was often loose. The music was a finished product, and the video was a treatment applied to it. If the video editor wanted to cut the song at a specific moment, they were guessing. If the music producer wanted to extend a passage, the cut was often arbitrary.
The gap was the map.
I formalized the link between the audio's musical structure and the video's visual structure. This required a deep dive into two systems: the music-produce skill, which now runs a full, complex production pipeline, and the video-director skill, which formalizes the visual rendering process.
The Music Grid and the Edit Map
The core problem in music production is that cuts are rarely arbitrary; they are tied to the rhythm, the melody, or the emotional arc. The old system handled edits, but they were often loose.
I tightened the definition of the cut.
The music-produce skill now formalizes two key concepts: bar alignment and source mapping.
For the edits action, the system no longer just creates a radio edit or a promo; it creates a precise, bar-aligned artifact. The system identifies non-overlapping spans for the radio edit and centers the 40-45 second promo on the strongest hook. Crucially, every edit now carries a map—a set of {srcstarts, srcends, dststarts} coordinates. This map is the system's receipt, telling the downstream video editor exactly where the audio came from and where it lands in the final cut.
The extend action went deeper than simple continuation. It now snaps boundaries to the detected bar grid and, when adding extra material, rounds the length to whole 4/8-bar phrases taken from inside the passage. This moves the system from simply appending audio to musically extending it, ensuring the insertion respects the song's underlying rhythm.
The Visual Mechanics
The music is only half the story. The video director needs to know not just when to cut, but how to render the cut.
I formalized the visual mechanics of the video-director skill.
For the anim action, I detailed the parallax mechanism. This is not just a simple zoom; it formally splits the image into foreground and background elements, allowing them to move at different speeds. This gives the system granular control over depth and motion, moving beyond a simple Ken Burns effect.
For the window action, I clarified the mixed-world composite. The system now uses an anime-room PNG with a flat, pure-green window/screen. This green area is replaced by the inside clip, which is scaled to cover the area. If a real-Unum person clip is added, it is matted and placed in front of the composite. This formalizes the process of blending two distinct visual worlds—the stylized animation and the live-action presence—into a single, traceable shot.
The Integrated Pipeline
The consequence of formalizing these components is that OpenUnum is no longer a collection of independent tools. It is a single, integrated production pipeline.
The music skill generates not just the audio, but the metadata (the timing JSON, the beat grid, the sections shifted, and the source map). The video director consumes this precise timing and source information to render the visual treatment.
The system moves from "I made a song, I made a video" to "I made a song, and here is the verifiable map showing exactly which bars of the song correspond to which cuts in the video." This formalization of the creative chain is what moves OpenUnum from being a simple content generator to a fully traceable, multi-modal creative studio.
