Go to [Google AI Studio](https://aistudio.google.com/apikey?utm%5Fsource=theaidrivenmarketer.beehiiv.com&utm%5Fmedium=referral&utm%5Fcampaign=youtube-shorts-automation-with-veo-3) 2. Click “Get API Key” 3. Create new API key 4. Copy and save securely **Cost:** Pay-per-use (see [pricing](http://about:blank#api-costs)) ### OpenAI API (GPT-4) 1. Go to [OpenAI Platform](https://platform.openai.com/api-keys?utm%5Fsource=theaidrivenmarketer.beehiiv.com&utm%5Fmedium=referral&utm%5Fcampaign=youtube-shorts-automation-with-veo-3) 2. Create new secret key 3. Copy immediately (shown only once) **Cost:** \~$0.01-0.03 per video script ### ElevenLabs API 1. Go to [ElevenLabs](https://elevenlabs.io/?utm%5Fsource=theaidrivenmarketer.beehiiv.com&utm%5Fmedium=referral&utm%5Fcampaign=youtube-shorts-automation-with-veo-3) 2. Sign up and navigate to API settings 3. Generate API key **Cost:** \~10,000 characters free/month, then pay-per-use ### Step 3: Set Up Cloudflare R2 Storage 1. **Create R2 Bucket:** 2. **Get API Credentials:** 3. **Configure Public URL:** ### Step 4: Configure FFmpeg (for audio-video merging) **Linux/Mac:** ``` # Install FFmpeg sudo apt-get install ffmpeg # Ubuntu/Debian brew install ffmpeg # macOS # Verify installation ffmpeg -version ``` **Docker n8n:** ``` # Add to Dockerfile RUN apk add --no-cache ffmpeg ``` **Note:** The workflow includes a code node that simulates merging. Replace with actual FFmpeg command in production. ### Step 5: Configure Gmail OAuth 1. **In n8n:** - Go to Credentials → Gmail OAuth2 - Click “Create New Credential” 2. **Google Cloud Console:** - Create project - Enable Gmail API - Create OAuth 2.0 credentials - Add authorized redirect: `https://your-n8n.com/rest/oauth2-credential/callback` 3. **Connect in n8n:** - Enter Client ID + Secret - Click “Connect my account” - Authorize access --- ## 💻 Usage ### Method 1: Web Form (Recommended) 1. **Get Webhook URL:** 2. **Share with Team:** - Send URL to content creators - Embed in internal tools - Add to website 3. **Submit Video Idea:** - Fill out form - Click “Generate Video” - Wait 2-3 minutes - Receive email with download link ### Method 2: API Call ``` curl -X POST '' \\ -H 'Content-Type: application/json' \\ -d '{ "video_idea": "Top 5 productivity hacks for remote workers", "target_audience": "Millennials (25-40)", "video_style": "Energetic & Fast-paced", "duration": "30 seconds", "voice_type": "Young Energetic Female", "email": "creator@company.com" }' ``` ### Method 3: Manual Execution (Testing) 1.

Check execution log for results --- ## 💰 API Costs ### Estimated Cost Per Video: | Service | Cost | Notes | | ----------------- | ---------------- | -------------------------------- | | **OpenAI GPT-4** | $0.01-0.03 | Script generation (\~500 tokens) | | **ElevenLabs** | $0.01-0.02 | \~200 characters voiceover | | **Google Veo 3** | $0.10-0.30 | 8-second 720p video | | **Cloudflare R2** | $0.00-0.01 | Storage + bandwidth | | **Total** | **\~$0.12-0.36** | Per video | ### Monthly Estimates: | Videos/Month | Estimated Cost | | ------------ | -------------- | | 50 videos | $6-18 | | 100 videos | $12-36 | | 500 videos | $60-180 | **Free Tiers:** - **ElevenLabs:** 10,000 characters/month free - **Cloudflare R2:** 10GB storage free - **OpenAI:** $5 free credit (new accounts) --- ## 🔧 Troubleshooting ### Common Issues: ### 1\. “Veo 3 video generation failed” **Cause:** API quota exceeded or invalid prompt **Solution:** ``` # Check API quota curl -H "x-goog-api-key: YOUR_KEY" \\ # Verify prompt length (max 1024 tokens) # Simplify complex prompts ``` ### 2\. “Voiceover generation timeout” **Cause:** ElevenLabs API slow or quota exceeded **Solution:** ``` # Check ElevenLabs quota curl -H "xi-api-key: YOUR_KEY" \\ # Reduce script length # Increase timeout in node settings ``` ### 3\. “Email not received” **Cause:** Gmail OAuth expired or spam folder **Solution:** ``` # Re-authenticate Gmail: 1. Go to Credentials in n8n 2. Delete old Gmail credential 3. Create new one 4. Re-authorize # Check spam/junk folders # Verify email address is correct ``` ### 4\. “Video download fails” **Cause:** Veo 3 URL expired (2-day limit) **Solution:** ``` # Videos expire after 48 hours # Download immediately after generation # Consider increasing storage retention ``` ### 5\. “Audio-video merge error” **Cause:** FFmpeg not installed or incorrect path **Solution:** ``` # Install FFmpeg sudo apt-get install ffmpeg # Verify installation ffmpeg -version # Update code node with correct FFmpeg path ``` --- ## ⚙️ Advanced Configuration ### Custom Voice Mapping Edit the `voiceover-generation` node to map custom voices: ``` // Voice ID mapping const voiceMap = { "Professional Male": "21m00Tcm4TlvDq8ikWAM", "Professional Female": "EXAVITQu4vr4xnSDxMaL", "Young Energetic Male": "pNInz6obpgDQGcFmaJgB", "Young Energetic Female": "jBpfuIE2acCO8z3wKNLl", "Custom Voice 1": "YOUR_VOICE_ID_HERE" }; const selectedVoice = voiceMap[$json.voice_type] || voiceMap["Professional Male"]; ``` ### Extend Video Duration Veo 3 supports up to 8 seconds per generation. For longer videos: 1. Generate multiple 8-second clips 2. Use Veo 3’s extension feature 3. Stitch clips using FFmpeg ### Add Watermark/Logo Update `merge-audio-video` node: ``` # FFmpeg command with watermark ffmpeg -i video.mp4 -i logo.png -i audio.mp3 \\ -filter_complex "[0:v][1:v]overlay=W-w-10:H-h-10" \\ -c:a aac -map 2:a output.mp4 ``` ### Batch Processing Enable batch mode to process multiple videos: 1. Replace form trigger with Google Sheets trigger 2. Read rows of video ideas 3. Loop through each row 4. Generate videos in parallel (max 3-5 concurrent) --- # FULL JSON Workflow ``` { "name": "🎬 YouTube Shorts Automation with Veo 3", "nodes": [ { "parameters": { "formTitle": "🎬 YouTube Shorts Video Generator", "formDescription": "Create professional YouTube Shorts videos with AI-powered script, voiceover, and Veo 3 video generation.

OpenAI and ElevenLabs allow commercial use. Ensure you have rights to any content you generate. **Q: How long does video generation take?** A: Typically 2-3 minutes total: - Script generation: 10-20 seconds - Voiceover: 5-10 seconds - Veo 3 video: 60-120 seconds - Processing: 10-20 seconds **Q: Can I customize the video style?** A: Yes! Edit the `veo3-prompt-enhancement` node to adjust: - Camera angles - Lighting - Color grading - Visual effects **Q: What happens if video generation fails?** A: The workflow includes error handling: - Retries up to 3 times - Logs detailed error messages - Sends notification email - Stores partial results for debugging **Q: Can I integrate with YouTube API for direct upload?** A: Absolutely! Add a YouTube upload node after video generation. See [n8n YouTube documentation](https://docs.n8n.io/integrations/builtin/app-nodes/n8n-nodes-base.youtube/?utm%5Fsource=theaidrivenmarketer.beehiiv.com&utm%5Fmedium=referral&utm%5Fcampaign=youtube-shorts-automation-with-veo-3). **Q: How do I reduce API costs?** A: Several strategies: - Use GPT-3.5 instead of GPT-4 for scripts - Cache common prompts - Implement rate limiting - Use free tier limits first - Process in batches during off-peak hours **Q: Can I use different video models?** A: Yes! The workflow can be adapted for: - Runway Gen-2/3 - Stability AI Video - Pika Labs - Other video generation APIs Just replace the Veo 3 nodes with the appropriate API calls. --- ## 📞 Support ### Getting Help: 1. **Check Logs:** 2. **Community Support:** - [n8n Community Forum](https://community.n8n.io/?utm%5Fsource=theaidrivenmarketer.beehiiv.com&utm%5Fmedium=referral&utm%5Fcampaign=youtube-shorts-automation-with-veo-3) - [n8n Discord](https://discord.gg/n8n?utm%5Fsource=theaidrivenmarketer.beehiiv.com&utm%5Fmedium=referral&utm%5Fcampaign=youtube-shorts-automation-with-veo-3) --- ## 📄 License This workflow is provided as-is for educational and commercial use.
