Create AI screencast videos with Claude, VEED, OpenAI and automated slides

Create AI screencast videos with VEED and automated slides

Overview

This n8n workflow automatically generates presentation-style "screen recording" videos with AI-generated slides and a talking head avatar overlay. You provide a topic and intention, and the workflow handles everything: scriptwriting, slide generation, avatar creation, voiceover, and video composition.

Output: Horizontal (16:9) AI-generated videos with animated slides as the main content and a lip-synced avatar in picture-in-picture, ready for YouTube, LinkedIn, or professional presentations.

What It Does

Topic + Intention → Claude writes script → Parallel processing:
 ├── OpenAI generates avatar → ElevenLabs voiceover → VEED lip-sync

Custom Avatar & Script Options

Custom Avatar Description

Leave custom_avatar_description empty to let Claude decide, or provide your own:

custom_avatar_description: "female marketing influencer, cool, working in tech"

Examples:

• "a woman in her 20s with gym clothes"
• "a bearded man in his 30s wearing a hoodie"
• "a professional woman with glasses in business casual"

Custom Avatar Image URL

Skip avatar generation entirely by providing a direct URL:

custom_avatar_image_url: "https://example.com/my-avatar.png"

> Image should be portrait orientation, high quality, with the subject looking at camera.

Custom Script

Leave custom_script empty to let Claude write it, or provide your own:

custom_script: "This is my custom script. AI is changing how we create content..."

Guidelines for custom scripts:

• Keep it 25-40 seconds when read aloud (60-100 words)
• Avoid special characters for TTS compatibility
• Write naturally, as if speaking

MCP Integration (Optional)

This workflow can be exposed to Claude Desktop via n8n's Model Context Protocol (MCP) integration.

To enable MCP:

1. Add a Webhook Trigger node to the workflow (in addition to the Manual Trigger)
2. Connect it to the ⚙️ Workflow Configuration node
3. Go to Settings → Instance-level MCP → Enable the workflow
4. Configure Claude Desktop with your n8n MCP server URL

Claude Desktop Configuration (Windows):

{
 "mcpServers": {
 "n8n-mcp": {
 "command": "supergateway",
 "args": [
 "--streamableHttp",
 "https://YOUR_N8N_INSTANCE.app.n8n.cloud/mcp-server/http",
 "--header",
 "authorization:Bearer YOUR_MCP_ACCESS_TOKEN"
 ]
 }
 }
}

> Note: Install supergateway globally first: npm install -g supergateway

Limitations & Notes

Technical Limitations

• tmpfiles.org: Temporary file URLs expire after ~1 hour. Final videos are safe in Google Drive.
• VEED processing: Takes 1-3 minutes for the talking head.
• Creatomate processing: Takes 30-60 seconds for composition.
• Total workflow time: ~3-5 minutes per video.

Content Considerations

• Scripts are optimized for 25-40 seconds (TTS-friendly)
• Avatar images are AI-generated (not real people)
• Slides are dynamically generated based on script length
• Slide count: 5-7 slides depending on script duration

Best Practices

1. Start simple: Test with default settings before customizing
2. Review scripts: Claude generates good content but review before posting
3. Monitor costs: Check API usage dashboards weekly
4. Use backgrounds: Adding a background image creates a more polished look
5. Match voice to content: Use Spanish voices for Spanish content

Troubleshooting

Issue	Solution
"Organization must be verified"	Verify at platform.openai.com/settings/organization/general
VEED authentication error	Re-add FAL.ai credential to VEED node
Google Drive "no binary field"	Ensure Download Video outputs to binary field
JSON parse error from Claude	Workflow has fallback content; check Claude node output
Slides not matching script	Increase seconds_per_slide for fewer slides
Avatar cut off in PiP	Avatar is designed for right-side placement
MCP "Server disconnected"	Install supergateway globally: npm install -g supergateway
Render timeout	Increase wait time in "⏳ Wait for Render" node
