Automated Instagram Reels Workflow with AI Captions

This workflow streamlines Instagram Reels automation with two trigger paths: a scheduled random video selector from a 'Random video mover' Google Drive folder, and a manual upload watcher for the 'n8n reels automation on instagram' folder. Videos are downloaded, processed, and posted seamlessly.

Core functionality includes downloading the video, generating concise AI captions with hashtags and CTAs using Google Gemini based on the filename, logging details (video name, caption, URL) to Airtable, and posting via Facebook Graph API. It addresses Meta's 2025 API changes by temporarily storing the video on the n8n server (/tmp/video.mp4), serving it via a public webhook with proper Content-Type headers, ensuring direct public URLs without authentication issues.

Post-upload, the temp file is cleaned up. Benefits include massive time savings on content creation and posting, boosted engagement from optimized AI captions, organized content tracking in Airtable, and reliable posting despite API restrictions. Ideal for fitness influencers, lifestyle brands, or marketers in social media needing consistent Reels output without manual effort.

Use cases: Fitness coaches scheduling motivational videos, lifestyle creators automating uploads, or agencies managing client Reels at scale.
