Auto-Post AI Veo3 Videos to YouTube with Sheets & SEO

This n8n workflow streamlines content creation for social media marketers by generating high-quality 8-second AI videos using Fal.ai's Veo3 model. It starts with a form trigger where users input a simple prompt, video style (e.g., Dialogue, Advertisement), aspect ratio, and YouTube category. The workflow then pulls style-specific details from Google Sheets, refines the prompt into a detailed script-to-screen format using OpenRouter's Google Gemini 2.5 Flash model, and sends it to Fal.ai for video generation. Request details are logged back to Sheets for tracking.

After a 5-minute wait to allow processing (typically 3-5 minutes), the workflow generates YouTube-optimized SEO elements like titles, descriptions, and tags using AI. Finally, it uploads the video directly to YouTube via the API, ensuring seamless publishing. This end-to-end automation eliminates manual video creation, editing, and uploading.

Benefits include massive time savings for consistent content posting, professional SEO for better visibility, and scalability for daily marketing campaigns. Ideal for real estate agents integrating MLS data for property tours, social media managers, or any business needing quick video ads. Enhances engagement on YouTube without design skills or expensive tools.
