Short answerA premise of at least 100 characters that names the lead, what they want, what stands in the way and the world's one unusual rule. Plus the in-story year, the genre, the platform and the dialogue language.
The lower half of the brief: episodes and duration are fixed by contract, casting preference, reference material and the rights checkbox.
The brief is the only input
Everything downstream grows from the brief: the bible, the scripts, the world pack. Once submitted the brief is immutable, so it is worth ten minutes of preparation.
Checklist
Title. The primary-language title; you can add other locales later.
Premise, 100 characters or more. Who the lead is, what they want, what stands in the way, and the one rule that makes this world different. Concrete beats vague; see how to write a premise that lands.
Era / year. The in-story year, for example 1587 or 2026. It drives every costume, set and prop for the whole series and is required. Read why the year matters.
Genre and tropes. Pick the closest genre; tick or type the tropes you want in the hook library.
Target platform. ReelShort, DramaBox, TikTok, YouTube or other. It is passed to the writers as context; it does not change episode length, format or price.
Primary language. The script and dialogue language, any BCP-47 locale. This is not a Chinese/English switch; pick the language your audience watches in.
Render style. Photoreal or comic.
Casting preference. Whether to reuse faces from your own roster and the shared library (free), or cast all-new faces (billed per character).
Reference material, optional. Text references you hold the rights to.
Rights. You will tick a box confirming no unauthorised real-person likeness and no third-party IP. Real-person references need written consent; never upload minors. See the Acceptable Use Policy.
Fixed by contract
Episode count is 10 and each episode runs 60 to 90 seconds at 1080×1920. These are not editable in the wizard for self-serve runs.
