Video Download Processing with Transcripts and Google Drive Upload for Businesses

This workflow automates video downloading and processing from platforms like YouTube and TikTok, replacing manual content capture, transcription, and repurposing that takes hours for marketing teams. The Video Request Gateway Webhook receives requests, the Request Validator Function node validates inputs, the User & Download Manager Postgres node checks subscriptions, the Download Quota Validator Function node enforces limits, the Video Metadata Fetcher HTTP Request node gets details, the Content Compliance Checker Function node verifies suitability, the Retatube Video Downloader HTTP Request node fetches videos, the Video Processor Function node generates metadata, the Cloud Storage Uploader Google Drive node stores files, the AI Feature Router If node routes to AI tasks, and HTTP Request nodes handle transcription, analysis, and repurposing. The Database Recorder Postgres node saves to a library, Quota Updater Postgres node tracks usage, Delivery Router Switch node selects email/Slack delivery, and Success Response Builder Function node formats outputs. It helps marketing teams in small agencies (10-30 staff) managing 200+ videos monthly, ensuring compliant, enriched content for campaigns.\n\nThis workflow saves 12-18 hours weekly processing 200 videos, reducing errors by 80%. Use cases include content repurposing for social media, legal archiving, or educational materials in marketing agencies. Suitable for small firms.
