Step-by-step Veo 3.1 text-to-video

1. Visit /video/veo-3-1

2. Set Generation Type to TEXT

3. Write a cinematic prompt

Veo rewards precise lighting and camera language:

Wide establishing shot of a glass cliffside house at dusk, warm interior lights glowing, slow drone push-in through coastal fog, photoreal, natural color grade, 16:9

4. Choose resolution + quality

Start 1080p + Lite for most marketing drafts.

5. Pick aspect ratio

9:16 short-form
16:9 YouTube / landscape ads
Auto when references dictate framing

6. Generate and evaluate

Check motion coherence, face stability, and whether the camera move matches the prompt. Adjust one clause at a time.

Advanced: first/last frame and references

First + last frame is perfect for product transitions (packaging → unboxing hero).
Reference mode keeps wardrobe, product design, or location consistency across takes.

Upload clean, well-lit images. Avoid heavy watermarks and busy collages.

Prompt formula that works on Veo

[Shot size] + [subject action] + [camera move] + [time of day / lighting] + [lens] + [mood]

Modifiers that help:

Photoreal, natural skin texture, physically accurate shadows
Anamorphic bokeh, 24mm wide, 85mm portrait
Overcast softbox, golden hour rim light, practical neon

Avoid dumping brand slogans into the prompt unless you truly need on-screen text (Veo is better at scenes than tiny typography).
