AI Video Creator: Veo3 to Social Media

This workflow automates the creation and publishing of viral videos using Veo3 AI and social media platforms, replacing manual content creation that consumes 15+ hours weekly for teams producing 20+ videos monthly. It generates video concepts, creates videos via Veo3, and posts to Instagram with AI-crafted captions, all triggered via a webhook. Key nodes include Webhook (Topic Input) for input, HTTP Request (AI Concept Generator) for content creation, HTTP Request (Veo3 Video Creator) for video generation, HTTP Request (Social Publisher) for posting, and RespondToWebhook (Success Response) for output. Ideal for content creators or marketing teams (3-10 staff) in media, e-commerce, or influencer marketing ($500K-$5M revenue), it reduces video production time by 90% for 20-200 videos monthly.\n\nSaves 13 hours/week on 20+ videos, improving efficiency by 90%. Suits viral marketing, social media automation, or content scheduling. Requires OpenAI API ($0.01-$0.10 per video, openai.com), Fal.ai API for Veo3 ($0.05-$0.20 per video, fal.ai), Instagram API (free with business account), n8n ($20/month cloud). Scalable to 500 videos/month; needs HTTPS.\n\nSetup Instructions:\n1. Install n8n via cloud.n8n.io or self-host (docker run -it --rm -p 5678:5678 n8nio/n8n).\n2. Set up OpenAI API at openai.com; configure devhubconnectOpenAi with API key.\n3. Set up Fal.ai API at fal.ai for Veo3; configure devhubconnectFalAi with API key.\n4. Set up Instagram API via Meta Developer; configure devhubconnectSocial with account ID and API key.\n5. Configure webhook (https://your-n8n.app/webhook/video-creator) for POST requests.\n6. Set environment variables: OPENAI_API_KEY, FAL_AI_API_KEY, INSTAGRAM_API_KEY, INSTAGRAM_ACCOUNT_ID.\n\nTesting:\n- POST {topic: 'A futuristic city adventure'}.
