How to Generate Brand-Ready AG1 Videos with Veo 3 + JSON Prompts

Introduction

Veo 3 has revolutionized AI video generation, and combining it with JSON prompting takes your outputs to the next level. Instead of manually writing paragraph prompts and hoping for coherent results, structured JSON allows for surgical-precision video creation, ensuring brand consistency across product videos.

This approach is perfect for creative strategists, growth marketers, and ad agencies who want predictable, high-quality video outputs without relying on the creative lottery.

Why JSON Prompting Works for Veo 3

Using JSON prompts gives you:

• Structured data instead of paragraphs: Each scene, camera angle, lighting choice, and brand element is explicitly defined.
• Precise creative direction: No guesswork; Veo 3 interprets exactly what you specify.
• Consistent brand-ready outputs: Perfect for product videos like AG1.
• Higher prompt coherence: Reduces randomness in generated videos.
• Predictable results: You know what the final video will look like before generation.

This is especially valuable for branded content where brand guidelines, colors, and messaging need to be consistent.

Step 1: Example JSON Prompt

Here’s the structured JSON prompt used for creating AG1 product videos with Veo 3:

{ "video_length": 8, "scenes": [ { "start": 0.0, "end": 2.0, "visual": "AG1 product pack rotates slowly on a minimalist pedestal, light reflecting off glossy surfaces.", "camera": "smooth crane shot, slight dolly-in", "lighting": "soft key light from left, subtle rim light from right", "audio": "ambient hum, subtle chime" }, { "start": 2.0, "end": 4.0, "visual": "Close-up of powder being poured into water, swirling, creating dynamic textures.", "camera": "macro focus, slow-motion", "lighting": "diffused top light, natural shadows", "audio": "soft bubbling, light swoosh" }, { "start": 4.0, "end": 6.0, "visual": "Branded shaker bottle fills with liquid, AG1 logo clearly visible.", "camera": "tracking shot around bottle, smooth orbit", "lighting": "rim light highlights logo, subtle reflections", "audio": "liquid pouring, soft chime accent" }, { "start": 6.0, "end": 8.0, "visual": "Final hero shot of AG1 product line with logo overlay, sparkling finish.", "camera": "static hero shot", "lighting": "soft glow on products, subtle vignette", "audio": "ambient fade-out, gentle sparkle sound" } ] }

Step 2: Input the JSON Prompt in Veo 3

1. Open the Veo 3 interface.
2. Copy and paste the JSON prompt exactly as shown above.
3. Select your generation mode (Fast, Quality, or Custom settings).
4. Start generation and watch Veo 3 render each scene with precise motion, lighting, and branding.

Step 3: Advantages of Structured JSON

Clear Scene Instructions

Every scene is defined with start/end times, camera angles, lighting, and audio cues.

Brand Consistency

AG1 logos, product colors, and textures are respected exactly in each render.

Predictable Output

No more random AI variations — each video matches your creative vision.

Time Savings

Eliminates repeated trial-and-error iterations typical with paragraph prompts.

Step 4: Tips for Maximizing Effectiveness

• Use exact brand colors and logos in your JSON for consistency.
• Define camera angles carefully: POV, crane, dolly, or macro for cinematic impact.
• Include audio cues to synchronize with motion and scene transitions.
• Test and tweak scene durations to perfect pacing and storytelling.

Conclusion

Veo 3 + JSON prompting unlocks predictable, brand-ready product videos with precision and efficiency. By structuring your prompt with cameras, lighting, scene details, and motion, you can generate high-quality videos for AG1 or any brand, avoiding the randomness of traditional AI video generation.

This technique isn’t just powerful now — in the coming months, brand videos will demand this level of precision, and using JSON prompts gives you a competitive edge.
