Generate metaphor-based product video ads with Gemini, Veo 3 and Creatomate

How it works

1. Brainstorm metaphors – Takes product details (name, description, audience, value props) and generates 5 visual metaphors using Gemini 2.5 Pro

2. Select best metaphor – Scores each metaphor on relevance, AI efficiency, simplicity, abstraction, and visual appeal, then picks the winner and creates a 3-act script + short title

3. Generate main video prompt – Translates the winning metaphor and script into a 120–150 word cinematic Veo 3 prompt with lighting, camera movement, and atmospheric details

4. Generate complementary scene – Creates a 40–60 word prompt for a static background plate that visually matches the main scene

5. Create both videos – Generates two 8-second AI videos with Veo 3.0 and uploads both to GCS

6. Merge & render – Combines the main video, complementary background, product name, and metaphor title using Creatomate

7. Deliver – Sends the final ad to Telegram

Set up steps

1. API Keys – Set up accounts for Google Cloud (Veo 3.0 + Gemini + GCS), Creatomate, and Telegram

2. Credentials in n8n – Add each API key as a credential in your n8n instance

3. Configure variables – Update the SET node with your Google Cloud PROJECT_ID and CLIENT_EMAIL

4. Enter product details – Fill in the Input variables node with your product name, description, target audience, and value propositions

5. Test – Execute the workflow to generate a metaphor-based video ad for your product
