Describe your idea

In “Create a video”, the “Story” tool offers two ways to start: “Describe your idea” and “Paste your script”. This page covers the first one: you give the idea, the AI writes the story, the lines and the shots. The “Your idea” field accepts long text (up to 20,000 characters), but three to six sentences are enough in most cases. What matters is what they contain.

The form that works

[Who] [does or discovers what], [where].
[What is wrong, or what they risk].
[The twist or the escalation, if you have one].
[How it ends, or the question left for the viewer].
Tone: [funny, unsettling, moving...]. Audience: [who should watch].

Each line feeds a precise step:

Part	What it gives the AI
Who, what, where	The characters to draw and the setting for the whole video
What is wrong	The stakes of the hook, the ones that hold people in the first 3 seconds
The twist	The mid video hook, which avoids dead time
The ending	The payoff, and the reason to comment
Tone and audience	The register of the lines, the voice and the music

Before / after

Weak
Strong

A horror story in a haunted house, with a dark and scary mood, cinematic style.

No character, no stakes, no ending. The screenwriter will fill the gaps with the most ordinary choices. “Cinematic style” is an image instruction, it has no place here.

A babysitter gets a text from the mother: “The kids are already asleep, don't come up.”
But she hears both children laughing upstairs.
She goes up anyway. The bedrooms are empty, the beds made.
Her phone buzzes: “I told you not to come up.”
Tone: slow tension, few words. Audience: teens who love horror.

A character, a place, a rule set then broken, an escalation, an ending that leaves a question. Each sentence can become a shot.

The “A theme” field and the “Random” button

If you don’t have an idea yet, the “A theme” field takes a single sentence (300 characters at most), for example “the village that loses a memory every night”. The AI then invents the whole story around it. The “Random” button suggests one for you. It is handy for exploring, but you control the result less: as soon as you know what you want to tell, switch to “Describe your idea”.

What you can add to the idea

Lines of dialogue. If you write at least four in the Name: line format, they are performed word for word. See Paste your script.
On-screen text. Markers like [CARD] or [COUNTER] also work in an idea written in prose. See On-screen overlays.
A length. If your idea mentions a length different from the one set, the app flags it (“Your idea asks for…”) and offers to apply it.
A staging constraint. “Locked shot on the door for the whole scene”, “we never see the father’s face”: the shot breakdown takes it into account.

Common mistakes

Writing image keywords instead of a story

“8K, ultra realistic, golden light” is useless in the idea. The look is set in “Style” and “Refine the style (optional)”. See References and style.

Telling three stories at once

A 30 to 60 second video holds a single idea. Cut, or turn it into a series.

Starting with the context

“In 1987, in a small village…” pushes the stakes back. Start with what is wrong: the date can come later.

Describing the characters in the idea and in the Characters field

If you fill in “Characters” in the references, don’t repeat their appearance in the idea: two descriptions that diverge give a face that changes.

Asking for exact on-screen text in prose

“With ATTENTION written in big letters” is likely to be drawn by the image model, with typos. Use [CARD] ATTENTION.

Settings that go with it

Video length: the story is written for this length. Start short to test.
Language: the language of the voice, the lines and the subtitles.
Tone: replaces or refines the tone written in the idea.
Voice, music, subtitles: in “Settings”.
Series: attach the video to a series to reuse its characters and its style. See Episodes.

After the writing, you review the story shot by shot before the images are paid for. It is the best moment to fix things. See Revising the story.
