Video transcript search and Q&A with VLM Run, GPT-4 & Google Workspace

Automate video transcription and Q&A with async VLM processing that scales from short clips to long recordings.

What this workflow does

1. Monitors Google Drive for new files in a specific folder and grabs the file ID on create 2. Automatically downloads the binary to hand off for processing 3. Sends the video to VLM Run for async transcription with a callback URL that posts results back to n8n 4. Receives the transcript JSON via Webhook and appends a row in Google Sheets with the video identifier and transcript data 5. Enables chat Q&A through the Chat Trigger + AI Agent. The agent fetches relevant rows from Sheets and answers only from those segments using the connected chat model
