The Scenario editor is where the story takes shape. Lines become beats. Beats become shots. Backgrounds split the script into scenes. You can write directly in the format, or paste free text and let LTB convert it.

​
Two ways to write

Pick the path that matches how you think.

Direct input

Type each line in the LTB format. Use @ for assets and / for blocks. Full control over structure, naming, and beat granularity.

Ingest

Paste a free-text outline and click Make scenario format & Set assets. LTB converts blocks, registers assets, and splits scenes in one pass.
The rest of this page covers direct input first. Ingest is documented at the end.

​
The scenario format

Each line is a unit of staging. Empty lines separate beats. [Background] blocks separate scenes.
That short script produces 7 beats across 2 scenes. The scene break happens where [Background] changes.

​
Three things you want to keep consistent

When a face, prop, or location appears more than once, register it. Registered items lock identity across every shot in the project. LTB sorts these into three asset types. Typing @ opens an autocomplete. Select an existing asset or create a new one inline.
@ autocomplete

@ opens the asset autocomplete

Line with character chip

Character bound to the line

Line with subject chip

Subject bound to the line

You must pick an entry from the autocomplete to bind the asset. Plain @name text without a selection is treated as a regular word, and the next shot can render a different face.

​
Backgrounds divide scenes

In film, a scene shifts when the set shifts. Cuts inside the same café belong to one scene. Cuts inside a car belong to the next. LTB applies the same rule — a Background block starts a new scene. Press / on an empty line and pick Background. Name the place, press enter, and LTB registers it.

The slash menu — pick Background

A registered background auto-generates four camera views — front, left, right, and rear — so camera angles can vary inside one scene without drifting environment.

​
Beats and addresses

A beat is one unit of staging — the smallest moment where an action changes. The term comes from Stanislavski, who taught actors to break a scene into beats and play each one as a discrete intention.
One beat equals one shot.
Press enter to end a line and start a new beat. Insert a Background to start a new scene. Every line then carries an address — a pair of (scene number, beat number) — and that address travels with the line through Image and Video stages. The vocabulary stays consistent across the product.

​
Four block types

A line carries one block. Most lines are Text. The other three serve specific roles. Text is the default — start typing. For Dialogue, Background, or Divider, press / on an empty line and pick from the slash menu.
Dialogue is stored as Speaker: body. The colon is the field separator, not a chooser — type the speaker name, a colon, then the line.

​
Korean and English

LTB sends line text to the model as written. There is no translation step. You can mix Korean and English inside the same project. Asset names should stay in one language to avoid duplicate registrations of the same character.

​
Ingest

Free-form outlines can become a structured scenario in one step. Write whatever shape you have, then click Make scenario format & Set assets at the bottom-left of the editor.
Ingest button

Ingest performs four operations in one pass.

Format conversion

Free text becomes Text, Dialogue, Background, and Divider blocks.

Asset registration

People, props, and places get registered as Characters, Subjects, and Backgrounds — with metadata filled in.

Scene splitting

Background blocks are inserted at every location shift.

Beat typing

Each beat receives a type label — intro, entrance, dialogue, close-up — that you can override.

​
When to use it

Reach for Ingest when:
  • You have a story in your head but no patience for hand-formatting.
  • You want a quick first draft from a short synopsis.
  • You want a generated starting point you can then revise by hand.

​
Direct input vs Ingest

The shortest comparison fits in five rows. Ingest output is fully editable. Treat it as a fast first draft — every line, asset, and scene break can still be revised with the direct-input tools above.
