Generate Videos from Images with Telegram, GPT-4.1 & Seedance/Veo3 Integration

🎥 Telegram Image-to-Video Generator Agent (Veo3 / Seedance Integration)
⚠️ This template uses [community nodes] and some credential-based HTTP API calls (e.g. Seedance/Wavespeed). Ensure proper credentials are configured before running.

🛠️ In the accompanying video tutorial, this logic is built as two separate workflows:

Telegram → Image Upload + Prompt Agent
Prompt Output → Video Generation via API

✨ What This Workflow Does
This powerful automation allows you to generate short-form videos from a Telegram image input and user prompt — perfect for repurposing content into engaging reels.

From the moment a user sends a photo with a caption to your Telegram bot, this n8n workflow:

📸 Captures the image and saves it to Google Drive
🧠 Uses an AI Agent (via LangChain + OpenAI) to craft a Seedance/Veo3-compatible video prompt
📑 Logs the interaction to a Google Sheet
🎞️ Sends the prompt + image to the Seedance (Wavespeed) API to generate a video
🚀 Sends the resulting video back to the user on Telegram — fully automated
