LLM TikTok Clipping from YouTube Podcasts Using AssemblyAI and Google Gemini

This workflow automates converting YouTube podcasts to TikTok clips, replacing manual transcription, editing, and clipping that take 2-4 hours per episode for content creators. The Form Trigger collects podcast/background URLs, validators check inputs, the Audio Downloader (HTTP Request to lemolex n8n webhook) extracts audio, waits/status checks poll progress, the Transcription Job Submitter (AssemblyAI) processes, the Transcription Extractor/Formatter Set nodes prepare text, the Highlight Extractor LangChain ChainLLM (Gemini 2.0-flash) identifies segments, the Highlight Splitter/Clip Processor split batches, the Main Clip Generator (lemolex webhook) creates videos, and Success Response Set outputs. It helps podcasters in small media firms (5-20 staff) producing 20+ clips weekly, enabling viral shorts without Premiere Pro, scaling reach while preserving quality.\n\nThis workflow saves 6-10 hours weekly on 20 episodes, boosting output by 75%. Use cases include daily highlights for wellness podcasts, branded snippets for marketing in startups. Suitable for solo creators or small teams.
