AI Reels Automation MVP

I need a compact workflow that can do everything for an Instagram Reel without human touch. Scope • The workflow starts with nothing more than a prompt. Using Google Veo (or Gemini where Veo access is limited), it must create a fully-formed 9:16 video. All footage, motion graphics, and transitions are AI-generated; no pre-recorded assets will be supplied. • While or immediately after rendering, the system analyses the clip and lets Gemini draft an engaging caption plus a high-reach hashtag set that reflects the actual content—no static templates. • Posts are pushed straight to my chosen Instagram Business account through the Instagram Graph API, so a working token refresh and simple scheduling field are required. Tech Stack Preference n8n orchestrates every step. Nodes (or custom actions) should call Gemini/Veo, pipe the results to a caption/hashtag generation step, and finish with the Graph API publish endpoint. If you can improve reliability with a brief fallback logic, feel free. Delivery Send me: 1. The n8n workflow JSON, ready to import 2. Any helper scripts or environment variables clearly documented 3. A one-page setup guide so I can replicate the MVP on a fresh VPS Acceptance Criteria • I trigger one n8n webhook; within minutes a Reel appears on the Instagram account with an AI-written caption and at least five relevant hashtags. • Video is vertical (1080×1920) and under 60 seconds. • Captions and hashtags align with a user-engagement focus—questions, hooks, calls-to-action, etc. • Entire process is automated end-to-end; no manual intervention after the initial trigger. When you reply, start with “LOW COST AI” and include your total price, delivery time, and, if possible, a link or short clip of a similar automation you have built.
