Create Veo3 videos using n8n

Today I got notice that the Veo3 API is publicly available through fal ai.

So I made a video that walks you through.

It's an impressive model BUT quite expensive. It's ~1$ per video second.

Here's the demo!

A bit about the flow.

How It Works

1. A user submits a video prompt through a form.

2. An AI agent (using OpenRouter's Google Gemini 2.5 Flash model) refines the user's prompt into a detailed "script-to-screen" format suitable for video generation.

3. The refined prompt is sent to the FalAI Veo 3 model via an HTTP request to generate the video.

4. Details of the video request, including the date, the refined prompt, and the request URL, are stored in a Google Sheet.

Setup

To run this workflow, you need to set up credentials in n8n for:

* OpenRouter: Generate API key from your OpenRouter account.

* Fal AI: Generate API key from your FalAI account

* Google Sheets: Uses OAuth 2.0. Connect by authenticating your Google account.
