Tacu uses a small set of working units so that story decisions, generated media, and timeline edits stay connected. A Scene holds a larger beat of the story. A Cut turns part of that Scene into a specific production and editing unit. Assets carry reusable project context, and tasks hold the work performed around a Cut.
Understanding these units makes it easier to answer two practical questions: “Where should I change this?” and “What else should I review after the change?”
| Unit | What it contains | Use it when |
|---|---|---|
| Project | The brief, Scenario, production assets, editor work, timeline, and exports | You need the complete context for one video |
| Scenario | The planned story, including Scene order, Cut descriptions, dialogue, and linked production context | You are checking whether the video plan supports the brief |
| Scene | A larger story beat with related action, place, or time | Several Cuts belong to the same part of the story |
| Cut | A focused production and editing unit inside a Scene | You need to generate, review, or replace a specific part of the video |
| Asset | Reusable character, appearance or outfit, location, and object context | The same visual fact needs to inform more than one Cut |
| Task | Scenario, image, video, voice or audio, music, or text work associated with the edit | You need to find the media or operation for a Cut |
How the units connect
In the lamp demo, Scene 1 takes place in a design studio and Scene 2 moves to a living space. Each Scene contains three Cuts. One Cut introduces the designer; another isolates the lamp's form; another shows the light changing the room. The protagonist, outfit, lamp, studio, and living-space assets give those Cuts a shared production context.
The Cut is where a broad story decision becomes something you can review. “The room becomes warmer” is a Scene-level change. A Cut makes it observable: what is in frame, what action occurs, and what the result must communicate. Image, video, and other task results can then be evaluated against that Cut.
A useful editing order
When a result does not work, diagnose it from the top down:
- Does the Scenario still match the project brief?
- Is the Scene clear about this part of the story?
- Does the Cut describe one understandable visual action or purpose?
- Are the right project assets connected?
- Does the selected task result satisfy the Cut?
- Does it still work when placed in the timeline?
This order prevents repeated generation from hiding an unresolved planning problem.
