Generate Videos from Chat with Google Vertex AI (Veo3)

Generate Videos from Chat with Google Vertex AI (Veo3) - Beginner Friendly

Description Turn 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.
