This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

🎬 Seedance Video Marketing AI Agent Description: This AI-powered marketing automation workflow takes a user prompt, researches trending topics, generates a compelling short-form video prompt, and sends it to the Seedance API via Wavespeed to create a ready-to-use video ad — all from a single Telegram message.

Built for marketers, founders, and content creators who want to turn trend-based ideas into visual video content without touching a video editor.
