AI Social Media Video Generator

This workflow automates social media video creation, replacing manual content production that consumes hours for marketing teams. It generates daily professional development videos using OpenAI for captions and scripts, Replicate for images, and ElevenLabs for voiceovers, then publishes to platforms like TikTok or LinkedIn. Key nodes include Schedule Trigger (runs daily at 9 AM), Code (selects content ideas), Code (generates captions/scripts), Code (creates images/audio), and Code (publishes and notifies via Slack). Ideal for businesses managing 5+ social accounts, like agencies or startups, it boosts engagement for teams of 3-20. The ROI saves 10-15 hours weekly by automating 30+ videos monthly, increasing engagement by 25%. Suits small to mid-sized firms. Requires OpenAI (~$0.50/video), optional Replicate (~$0.10/image), ElevenLabs (~$0.05/audio). Scales to 100 videos/month; monitor API limits. Needs n8n and JSON skills. Install n8n via n8n.io (self-hosted) or cloud.n8n.io (hosted). Get OpenAI key from openai.com/dashboard/api-keys, Replicate token from replicate.com/account, ElevenLabs key from elevenlabs.io. Set environment variables (OPENAI_API_KEY, optional REPLICATE_API_TOKEN, ELEVENLABS_API_KEY, SOCIAL_WEBHOOK_URL, SLACK_WEBHOOK_URL) in n8n settings. Configure Social Publisher node with platform-specific webhooks. Code nodes use Bearer auth for APIs. Test with sample idea in Content Idea Generator node. Verify captions, images, and Slack notifications. Common errors: invalid API keys (check dashboards), rate limits (add delays in Code nodes), webhook issues (validate URLs). Activate workflow in n8n; runs daily. Monitor API usage, rotate keys quarterly, optimize by caching prompts.
