Auto-Create Viral Shorts: RenderIO & OpenAI for n8n Workflows

Transform your long-form videos into viral short clips automatically with this powerful n8n workflow that combines OpenAI's intelligence with RenderIO's cloud rendering capabilities. Perfect for content creators who want to repurpose content without manual editing.

What this workflow does

This automated system monitors your Google Drive folder and springs into action whenever you upload a new video. Here's the complete process:

• Automatic Detection: Polls your designated Google Drive folder every minute for new video uploads
• Audio Extraction: Downloads the video and uses RenderIO's cloud-based FFmpeg to extract the audio track
• AI Transcription: Processes audio through Whisper AI to generate accurate transcripts in both TXT and SRT formats
• Smart Clip Selection: Sends transcripts to OpenAI, which analyzes content and identifies the most engaging highlight moments with precise timestamps
• Multi-Format Rendering: Creates each selected clip in three optimized aspect ratios - 9:16 for TikTok and Instagram Reels, plus 1:1 for square social posts
• Organized Output: Uploads finished clips back to Google Drive and logs every processing run to a Google Sheet for tracking

Use cases

• YouTubers: Automatically create short-form content from podcast episodes, tutorials, or live streams
• Social Media Managers: Repurpose webinars, interviews, and presentations into engaging social clips
• Content Creators: Scale video content production without hiring additional editors
• Marketing Teams: Extract highlight reels from product demos and company events
