"content": "🎬 Generate Videos from Chat with Google Vertex AI (Veo3)\n\nDescription\nTurn any text prompt into a short AI-generated video directly from an n8n chat. This workflow connects a chat trigger to Google Vertex AI’s Veo3 model, sending your prompt as input and polling until the rendered video is ready. Once complete, the video is converted into a downloadable file you can use anywhere. Perfect for experimenting with AI-driven media or automating creative video generation inside your workflows.\n\nWatch step-by-step guide for these type of workflows here:\nwww.youtube.com/@automatewithmarc\n\nHow It Works\n\nChat Trigger – Start by typing your prompt into an n8n chat.\n\nPost to Vertex AI (Veo3) – Sends the prompt to the Veo3 API with parameters like aspect ratio, duration, and resolution.\n\nWait + Poll Loop – Repeatedly checks the operation status until the video is finished.\n\nIf + Edit Fields – Extracts the base64 video response and metadata.\n\nConvert to File – Turns the video into a binary file for download or use in further automations.\n\nWhy You’ll Love It\n\n⚡ Generate custom AI videos in minutes.\n\n🗣️ Natural workflow — just type your idea in chat.\n\n🎥 Flexible parameters — adjust resolution, aspect ratio, and duration.\n\n🔗 Ready for integration — feed the output into Google Drive, Slack, or any connected app.\n\nRequirements\n\nGoogle Cloud project with Vertex AI API enabled.\n\nGoogle OAuth credentials in n8n.\n\nn8n (Cloud or self-hosted)."
