Master JSON Prompting

Summary: JSON prompting is a new technique that lets you script every detail of your AI video like camera angles, lighting, motion, even sound design, all inside a single prompt. With just a few tweaks, you can generate stunning AI videos in minutes using ChatGPT and Flow.

🧰 Who is this useful for:

• Marketers building high-impact ad creatives

• Founders and solopreneurs running lean campaigns

• Video creators who want precise control over AI output

• Agencies producing fast-turnaround brand content

STEP 1: Understand What JSON Prompting Is

Instead of one messy block of text, JSON prompting breaks your prompt into clear fields:

✅ AI loves structure. Think of it like GPS directions — it follows much more precisely compared to a vague prompt.

STEP 2: Generate Your JSON Prompt with ChatGPT

Open ChatGPT and ask it to write a JSON prompt for your video idea.

Write a detailed prompt like: “Write JSON prompt for a cinematic Tesla ad where a branded crate in a peaceful meadow opens to reveal a Tesla car, as a nature-tech pavilion elegantly forms around it with "TESLA" written”

ChatGPT will return a block of structured code with:

→ Camera movements

→ Scene transitions

→ Lighting setups

→ Sound cues

You can tweak anything — swap your product, change the setting, or adjust the mood

STEP 3: Paste It into Flow with Veo 3

Once your JSON prompt is ready, head over to Flow:

→ Start a new project

→ Select Veo 3 as your video model

→ Paste your full JSON prompt

→ Click Generate

Within minutes, Flow will render a cinematic-grade video based on your detailed structure.

Pro tip: Instead of settling for one style, ask ChatGPT to generate 3 variations of your JSON prompt cinematic, commercial, and UGC-style. This gives you creative range and lets you test which vibe performs best for your audience or ad goals.
