Generate Sora v2 ASMR clips with GPT-5.1, stitch via Cloudinary, and post to Twitter/X

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
