Structure

A Vidu Q4 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 16 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

    Sound

    Vidu Q4 generates synchronized audio with the clip, so name the ambience, effects or lines of dialogue you want.

  7. 07

    References

    Say what each reference controls, e.g. @Image1, @Audio1: “@Image1 is the main character”.

By task

Prompting each Vidu Q4 task

Image to Video

The image is the first frame: describe what moves and how the camera moves, not what the picture already shows.

Reference to Video

Attach references and mention them in the prompt by name, saying what each one should control — character, product, style or camera move.
