When the AI writes, it builds the script in segments of about 100 words until it reaches the word target for your bracket. It opens with a hook sentence, keeps one open question running through the middle, and ends on a payoff, then drafts a title, a description and four hashtags. It writes one continuous narration: no headings, no chapter markers, no paragraph breaks.
That shape works well for a Short and thins out over 12 minutes, because one open question rarely holds that long. The fix is to give the structure yourself. Write an outline into the prompt, something like “Five sections: the setting, the first warning, the decision, the collapse, what changed after. End each section on a question the next one answers,” and the script will generally follow that plan. Check that it did before you render.
If you want full control, write the script and paste it into the Script template instead, up to 1,800 words. Read it aloud once before you do; anything you trip over, the narrator will trip over for twelve minutes.
