The pipeline

Scale is decided before the camera rolls.

Five steps turn a brief into an episode where nobody drifts. Here is what happens to your cast at each one.

Five steps, one scale.

  1. Step 01

    Passport

    Lock a character once: height in centimetres, proportions in heads, build, palette, outfit, things they must never do, and a voice. Every episode pins the passport version it used.

    Pip · 62 cm · 3 heads

  2. Step 02

    Plan

    The Yarnix planner turns your brief into a shot list. The first beat of every scene is a full-body scale anchor, so sizes are fixed before anything moves.

    shot 01 · wide · scale anchor

  3. Step 03

    Keyframe

    Video models accept no height. So the first frame of each shot is composed from the passports — camera height, floor line, each character's pixel height — and then animated.

    eye line · floor · caption zone

  4. Step 04

    Takes & QC

    A vision check scores identity and outfit and measures relative heights. A take that drifts past ±7 % is cut and reshot, inside the hold you approved.

  5. Step 05

    Delivery

    You get the vertical episode with captions clear of the platform interface, and a receipt: shots, rejected takes with reasons, and credits quoted, charged and refunded.

This is the same layout math that composes every keyframe. Change a height and read the scale notes the prompt gets.
