Structure

A Vidu Q3 Mix prompt, piece by piece

Write in this order and keep each part concrete. Physical detail works better than mood words.

  1. 01

    Subject

    Who or what is on screen, with the details that must stay consistent: age, clothing, materials, colours.

  2. 02

    Action

    One clear action in the present tense. For clips up to 15 s, describe a short sequence of beats.

  3. 03

    Camera

    Shot size and movement: close-up, wide, dolly-in, orbit, handheld, drone.

  4. 04

    Scene and light

    Location, time of day, and where the light comes from.

  5. 05

    Style

    Lens, film look, colour grade or animation style.

  6. 06

    References

    Say what each reference controls, e.g. @Image1: “@Image1 is the main character”.
