Generate Sora videos, stitch clips, and post to Twitter

Generate creative ASMR cutting video concepts with GPT-5.1, create high-quality video clips using Sora v2, stitch them together with Cloudinary, and automatically post to Twitter/X—transforming ideas into viral content without manual video editing.

How it works

Step 1: Generate Video Concepts

  • Schedule Trigger activates the workflow automatically
  • GPT-5.1 AI agent generates 3 unique ASMR cutting scene prompts with unusual objects
  • Creates structured video prompts optimized for Sora v2 (frontal camera angle, cutting actions)
  • Generates Twitter-ready captions with relevant hashtags
  • Saves all concepts and scripts to Google Sheets for tracking

Step 2: Create Video Clips with Sora v2

  • Generates 3 separate Sora v2 video clips in parallel (8-12 seconds each)
  • Each clip uses unique prompts from GPT-5.1 output
  • Videos render at 720x1280 resolution (vertical format for social media)
  • System waits 30 seconds for rendering to complete

Step 3: Monitor & Download Videos

  • Loops through all 3 video generation requests
  • Checks Sora API status every 30 seconds until rendering completes
  • Automatically skips failed renders (continues workflow with successful videos)
  • Downloads completed videos from Sora API
  • Uploads each clip to Cloudinary for storage and processing

Step 4: Stitch Videos Together

  • Collects all uploaded Cloudinary video IDs
  • Builds Cloudinary transformation URL to stitch 3 clips into one seamless video
  • Applies Twitter-compatible encoding (H.264 baseline, AAC audio, MP4 format)
  • Downloads the final stitched video

Step 5: Upload to Twitter/X

  • Prepares video file data and calculates total file size
  • Uses Twitter's chunked upload API (INIT → APPEND → FINALIZE)
  • Waits for Twitter's video processing to complete
  • Checks processing status until video is ready
  • Posts tweet with AI-generated caption and attached video
  • Updates Google Sheets status to "Posted"

What you'll get

  • AI-Generated Concepts: Creative ASMR cutting ideas with unusual objects (glass avocados, lava rocks, rainbow soap)
  • Professional Video Clips: Three 8-12 second Sora v2 videos per concept with 720x1280 resolution
  • Seamless Stitching: Single combined video optimized for Twitter/X specifications
  • Engaging Captions: GPT-5.1 generated tweets with hashtags designed for virality
  • Automated Posting: Direct upload to Twitter/X without manual intervention
  • Cloud Backup: All videos stored in Cloudinary with metadata
  • Progress Tracking: Google Sheets integration shows workflow status (In Progress → Posted)
  • Error Handling: Failed Sora renders are automatically skipped

Why use this

  • Save 4+ hours per video: Eliminate scripting, shooting, editing, and posting time
  • Consistent posting schedule: Set it and forget it with the Schedule Trigger
  • Scale content creation: Generate multiple video variations in 20-30 minutes
  • Professional quality: Leverage Sora v2's AI video generation for realistic cutting scenes
  • Optimize for virality: GPT-5.1 creates concepts and captions designed for engagement
  • Reduce creative burnout: AI handles ideation, execution, and distribution
  • No video editing skills needed: Complete automation from concept to post
  • Test multiple concepts: Generate 3 variations per run to see what resonates

Setup instructions

Required accounts and credentials:

  1. OpenAI API Key (GPT-5.1 and Sora v2 access required)

    • Sign up at https://platform.openai.com
    • Ensure your account has Sora v2 API access enabled
    • Generate API key from API Keys section
    • Note: Sora v2 is currently in limited beta

  2. Google Sheets OAuth (for tracking video ideas and status)

    • Free Google account required
    • Create a spreadsheet with columns: Category, Scene 1, Scene 2, Scene 3, Status
    • n8n will request OAuth permissions during setup

  3. Cloudinary Account (for video storage and stitching)

    • Sign up at https://cloudinary.com (free tier available)
    • Note your cloud name from the dashboard
    • Create an upload preset named n8n_integration
    • Enable unsigned uploads for the preset

  4. Twitter OAuth 1.0a Credentials (for automated posting)

    • Apply for Twitter Developer access at https://developer.twitter.com
    • Create a new app in the Developer Portal
    • Generate: API Key, API Secret, Access Token, Access Token Secret
    • Enable "Read and Write" permissions (not just Read)
    • OAuth 1.0a is required for media uploads (OAuth 2.0 won't work)

Configuration steps:

  1. Update OpenAI API Key:

    • Add your OpenAI API key to these nodes:
      • "OpenAI Chat Model" credentials
      • "Create Sora Video Scene - 1" (Authorization header)
      • "Create Sora Video Scene - 2" (Authorization header)
      • "Create Sora Video Scene - 3" (Authorization header)
      • "Check Video Status" (Authorization header)
      • "Download Completed Video" (Authorization header)
    • Replace Bearer API KEY with Bearer YOUR_ACTUAL_API_KEY

  2. Configure Google Sheets:

    • Open "Save Category and Clip Scripts" and "Update Status" nodes
    • Authenticate with your Google account (OAuth 2.0)
    • Select your spreadsheet and sheet name
    • Ensure columns match: Category, Scene 1, Scene 2, Scene 3, Status
    • The workflow will update Status from "In Progress" to "Posted"

  3. Update Cloudinary Settings:

    • In "Upload to Cloudinary" node:
      • Replace {Cloud name here} in the URL with your Cloudinary cloud name
      • Verify upload preset is set to n8n_integration
    • In "Build Stitch URL" node:
      • Open the Code node
      • Replace dph9n4uei on line 1 with your cloud name
      • This builds the video stitching transformation URL

  4. Add Twitter OAuth 1.0a Credentials:

    • Configure OAuth 1.0a in these nodes:
      • "Twitter Upload - INIT"
      • "Twitter Upload - APPEND"
      • "Finalize Upload"
      • "Check Twitter Processing Status"
      • "Post a Tweet"
    • Use the same OAuth 1.0a credential for all nodes
    • Ensure your Twitter app has "Read and Write" permissions

  5. Adjust Schedule Trigger (optional):

    • Default: Runs on every interval
    • Modify in "Schedule Trigger" node to set specific times
    • Recommended: Once per day or every few hours to avoid rate limits

  6. Test the workflow:

    • Click "Execute Workflow" to test manually first
    • Verify GPT-5.1 generates 3 video concepts
    • Check that Sora v2 creates all 3 videos
    • Confirm Cloudinary stitches videos correctly
    • Ensure Twitter post appears with video and caption

Important notes:

  • Sora API Rate Limits: Sora v2 may have rendering quotas. Monitor your usage
  • Video Rendering Time: Each Sora clip takes 2-5 minutes. Total workflow: 15-25 minutes
  • Failed Videos: The workflow automatically skips failed renders and continues
  • Twitter Video Limits: Maximum 512MB per video, MP4 format required
  • Cloudinary Free Tier: 25 credits/month includes video transformations
  • Cost Estimate: ~$1-3 per run (Sora API pricing varies)

Troubleshooting:

  • "Sora API access required": Contact OpenAI to enable Sora v2 API on your account
  • Twitter upload fails: Verify OAuth 1.0a credentials have "Read and Write" permissions
  • Cloudinary upload fails: Check cloud name and ensure upload preset exists
  • Videos don't stitch: Verify all 3 videos uploaded successfully to Cloudinary
  • Google Sheets not updating: Confirm OAuth permissions and sheet column names match

Next steps:

  1. Enable the Schedule Trigger to automate daily/weekly posts
  2. Monitor Google Sheets to track posted content
  3. Adjust GPT-5.1 prompts in "ASMR Cutting Ideas" for different content themes
  4. Experiment with different video durations (8 vs 12 seconds)
  5. Add error notifications using Email or Slack nodes
