Generate short VSL videos with GPT-4o, Google Veo 3.0, Creatomate and Telegram

How it works

1. Gather product info – Takes product details (name, audience, tone, CTA, script) and product image URL from a form

2. Describe the product – Uses GPT-4o to analyze the product image and generate a detailed visual description

3. Generate VSL prompt – Uses GPT-4o to consolidate the script and product description into a single 120–180 word Veo 3 prompt with centered framing, action cues, and dialogue formatting

4. Create video – Generates an 8-second AI video with Veo 3.0 and uploads to GCS

5. Add captions – Uses Creatomate to overlay captions onto the video

6. Deliver – Downloads the final video and sends it to Telegram

Set up steps

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

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

3. Configure variables – Update the SET1 node with your Google Cloud PROJECT_ID and CLIENT_EMAIL

4. Enter product data – Fill in the Form node with your product name, target audience, tone, call to action, and script

5. Test – Execute the workflow to generate a VSL for your product
