Generate Biblical Character Vlogs with GPT-4o and Veo3 AI Video Generator

🧠 How It Works

This intelligent workflow turns ancient stories and legendary characters into modern-style vlog ideas — then automatically builds cinematic prompts ready to generate short videos using Veo3.

Think: “What if biblical figures had GoPros?” — funny, emotional, and visually stunning AI-made videos.

🔄 Workflow Steps

✨ 1. Concept Generator (AI Node 1)

The first AI agent creates a video concept inspired by a biblical or mythological theme.
It structures output as JSON with:

• 🎬 caption – Short, emotional or humorous line with emojis & hashtags
• 💭 concept – A short summary of the story or moment captured on camera
• 🌄 setting – Visual and mood details (lighting, style, colors)
• 📋 status – Stage label like “draft” or “to produce”

Example Output:

{
 "caption": "POV: Moses trying to record a vlog mid–Red Sea split 🌊📹 #faithvibes #holyshorts",
 "concept": "Moses looks straight into the camera, trying to act calm while walls of water rise dramatically beside him.",
 "setting": "Vast sea corridor glowing in blue light, reflections dancing on wet sand, robes fluttering in the wind.",
 "status": "to produce"
}

🎬 2. Cinematic Prompt Builder (AI Node 2)

This agent converts the concept and setting into a Veo3-ready cinematic prompt that guides realistic video generation.

Each output includes:

• Scene layout & description 🌅
• Character framing & expression 🎭
• Camera movement (pan, orbit, dolly-in, etc.) 🎥
• Lighting style & atmosphere 💡
• Textural realism (dust, wind, shadows, fabrics)

Example Output:

A robed man stands between two towering walls of water, facing the camera as waves shimmer in the light. The handheld camera slowly pushes forward, capturing ripples and wind-blown fabric. His tone is confident yet tense. The atmosphere feels surreal — reflections glisten and mist drifts through golden rays.

☁️ 3. Send to Veo3 API

The cinematic description is sent directly to the Veo3 video generation API to create the visual clip.

POST Request
https://queue.fal.run/fal-ai/veo3

• Header → Authorization: Key YOUR_API_KEY
• Body → { "prompt": "{{ $json.output }}" }

The API responds with a request_id to track progress.

⏳ 4. Track Video Progress

Monitor generation status and retrieve your final clip details.

GET Request
https://queue.fal.run/fal-ai/veo3/requests/{{ $json.request_id }}

• Header → Authorization: Key YOUR_API_KEY

When complete, the Veo3 model delivers your AI-generated short film.

⚙️ Setup Guide

1. Connect APIs

• Create a Veo3 (fal.run) account
• Copy your API key → Add it under Header Auth: Authorization: Key YOUR_API_KEY

2. Customize Prompts

• Change the core question in Node 1 to explore other themes — e.g., “Greek myths,” “ancient warriors,” or “historic leaders.”
• Refine the camera and lighting tone in Node 2 for different cinematic vibes (gritty, vintage, surreal).

3. Run & Validate

• Trigger manually to test flow
• Check JSON output → must include caption, concept, setting, status
• Ensure Veo3 receives your cinematic prompt correctly

4. Automate & Expand

• Add a Scheduler to generate new ideas daily or weekly
• Send results to Google Sheets, Notion, or Discord for creative collaboration
