Structure
A Veo 3.1 Fast prompt, piece by piece
Write in this order and keep each part concrete. Physical detail works better than mood words.
01
Subject
Who or what is on screen, with the details that must stay consistent: age, clothing, materials, colours.
02
Action
One clear action in the present tense. Keep it to one beat for short clips.
03
Camera
Shot size and movement: close-up, wide, dolly-in, orbit, handheld, drone.
04
Scene and light
Location, time of day, and where the light comes from.
05
Style
Lens, film look, colour grade or animation style.
06
Sound
Veo 3.1 Fast can add native audio (billed at a higher rate): describe ambience, effects or dialogue when generate_audio is on.

By task
Prompting each Veo 3.1 Fast task
Text to Video
Everything comes from the text, so describe subject, action and camera explicitly. Put the most important element first.
Image to Video
The image is the first frame: describe the motion and camera from that frame instead of re-describing the picture. Add a last frame to control where the shot ends.
