Whether you’re a marketer, content creator, educator, or AI enthusiast, this system unlocks unprecedented creative freedom. Let’s dive in.
What Is the “10-Minute Character Video” System?
The system is an automated AI workflow that generates long-form videos (up to 10+ minutes) featuring a chosen character who speaks in a consistent, high-quality voice throughout the entire video. The character can be placed into different scenes while retaining vocal identity—critical for building recognizable, repeatable personalities.
Key capabilities include:
- Voice consistency: The same voice remains unchanged across scripts and scenes.
- Character flexibility: Works with real people, animated figures (like Mario and Luigi), or original creations.
- Multi-use applications: From calm ASMR and meditation content to energetic product promos and educational explainers.
- Full automation: Once set up, the system runs with minimal human intervention.
Real-World Use Cases for AI Character Videos
The transcript highlights several compelling applications:
Podcasting with AI Avatars
Host podcasts using AI versions of yourself or fictional characters. As demonstrated: “Thanks to this build by Robbo Nuggets, we can finally host our own podcasts together. Right, Luigi?”
Product Promotion
Promote products like “zero alcohol wine that is 50% off this Black Friday” using a branded character who speaks naturally about the offer.
Educational Content
Create explainer videos—e.g., “a film that teaches people about emotions”—with a consistent narrator who builds trust over time.
ASMR and Meditation
Generate “calm, relaxing meditation or ASMR videos” with soft, steady, peaceful narration.
AI Influencers and Personal Branding
Real-world examples include:
- AI influencers with millions of followers despite being computer-generated.
- Educational creators like Zinny Studio, who uses a character to teach.
- Real people using AI avatars to post “several times a day” without recording each time.
Important Ethical Note: While the video uses familiar characters like Mario for demonstration, the creator emphasizes: “what you should use this quite powerful tech for are characters that you create or have license to.” This ensures long-term value and legal safety.
Why Voice Consistency Matters
Consistent voice is essential for building recognizable, trustworthy AI personas. Without it, your character feels disjointed or artificial. The system ensures that whether your character talks about space travel or wine deals, their voice remains “smooth as butter the whole way through,” thanks to pre-selected voice models from 11 Labs via Wavespeed.ai.
Meet the Core AI Model: Infinity Talk
After testing “several hours and hundreds of credits” across multiple long-form AI video models, the team identified Infinity Talk (accessed via Wavespeed.ai) as the best option.
Why Infinity Talk Stands Out
- Delivers high-quality, lifelike lip-sync and facial animation.
- Maintains voice consistency when paired with 11 Labs audio.
- More cost-effective than competing models (see cost comparison below).
- Supports long-form content (5–10+ minutes).
Tool Stack Overview
The entire system is built using a combination of AI services and no-code automation:
| Tool | Purpose | Key Feature |
|---|---|---|
| N8N | No-code automation platform (like Zapier or Make.com) | Orchestrates the entire workflow from input to output |
| Wavespeed.ai | AI model aggregator and API gateway | Provides pay-as-you-go access to 11 Labs and Infinity Talk |
| 11 Labs | Voice generation | High-quality, expressive, consistent synthetic voices |
| Infinity Talk | AI video generation | Animates still images using driving audio |
| Google Sheets | Input management & output logging | Stores scripts, voice IDs, image URLs, and video outputs |
| Key.ai (Cdream model) | Character image generation | Generates 4K images with custom aspect ratios |
| Google Gemini | Alternative image generation (free) | Limited control over aspect ratio |
Step-by-Step: Building the Automation in N8N
The full workflow is built in N8N. Here’s how to recreate it from scratch.
Step 1: Create a New Workflow
In your N8N dashboard, click “Create Workflow.”
Step 2: Add a Manual Trigger
Add a manual trigger node. This lets you run the workflow on demand by clicking “Execute Workflow.” (You can later switch to a scheduled trigger for automated daily posts.)
Step 3: Connect Google Sheets for Input
Add a Google Sheets node using the “Get Rows in Sheet” function. Configure it to:
- Connect your Google account.
- Select your input sheet.
- Filter rows where
task_status = "create". - (Optional) Enable “Return only first matching row” to process one video at a time.
Step 4: Prepare Your Input Sheet
Your Google Sheet must include these columns:
- script: The full text your character will speak.
- voice_id: The ID of your chosen 11 Labs voice.
- image_reference: URL to your character’s image.
- row_number: Auto-filled by Google Sheets.
- task_status: Starts as “create,” updates to “done” or “error.”
- output: Where the final MP4 URL will be stored.
- estimated_cost: Optional column for cost tracking.
How to Get Your Character Image
You need a high-quality image of your character. Two recommended methods:
Option 1: Key.ai (Cdream Model) – Recommended
- Go to key.ai and use the Cdream model.
- Enter a prompt (e.g., “cartoon plumber in red hat, friendly expression”).
- Specify image size (e.g., 1920×1080 for horizontal videos).
- Generate in 4K and select your favorite.
- Use the “Edit” feature to insert your own character into new scenes.
- Right-click the final image → “Copy image address” → paste as
image_referencein Google Sheets.
Option 2: Google Gemini – Free but Limited
- Use for quick, free image generation.
- Drawback: Cannot specify aspect ratio, making it hard to get consistent video framing.
How to Get Your Voice ID from 11 Labs
Follow these steps to select and copy a voice ID:
- Go to 11 Labs → Voice Library.
- Browse or search for a voice that matches your character’s personality (happy, sad, calm, energetic).
- Click on a voice to preview it (e.g., “I tell you, the family is the only important thing in the world.”).
- Click the ellipsis (â‹Ż) menu next to the voice.
- Select “Copy Voice ID.”
- Paste this ID into the
voice_idcolumn in your Google Sheet.
Generating the Voiceover via Wavespeed.ai
Instead of using 11 Labs directly, the system uses Wavespeed.ai as an API gateway for easier automation and pay-as-you-go pricing.
Set Up the “Create Voice” HTTP Request Node
- Add an HTTP Request node. Rename it “Create Voice.”
- Set method to POST.
- URL:
https://api.wavespeed.ai/v1/generate(or the 11 Labs endpoint via Wavespeed). - Body (JSON):
{ "model": "elevenlabs", "text": "={{ $json.script }}", "voice_id": "={{ $json.voice_id }}" }
Configure Authentication
- Go to Authentication → Generic Credential Type → Header Off.
- Create a new credential named “Wavespeed API.”
- Header Name:
Authorization - Value:
Bearer YOUR_WAVESPEED_API_KEY - Get your API key from Wavespeed.ai → Profile → API Keys.
Add a Wait Node
After the voice request, add a Wait node for 20 seconds to allow processing time.
Fetch the Generated Audio
Add another HTTP Request node (method: GET) using the audio_url returned by the first request. This retrieves the MP3 file.
Handling Processing States with a Switch Node
Since AI generation takes time, use a Switch node to handle different statuses:
| Routing Rule | Condition | Action |
|---|---|---|
| Success | status == "completed" |
Proceed to video generation |
| In Progress | status == "processing" |
Loop back to Wait node |
| Fallback (Error) | Any other status | Log error in Google Sheets |
Generating the Video with Infinity Talk
Once audio is ready, generate the video using Infinity Talk via Wavespeed.
“Create Video” HTTP Request Node
- Method: POST
- URL: Infinity Talk endpoint from Wavespeed API docs
- Body (JSON):
{ "model": "infinity_talk", "audio_url": "={{ $json.audio_url }}", "image_url": "={{ $json.image_reference }}", "resolution": "720p", "prompt": "minimal movement" }
Note: The prompt field is optional. Use it to guide behavior (e.g., “smiles a lot,” “minimal movement”).
Wait and Poll for Completion
- Add a Wait node (30 seconds).
- Add a GET request to fetch video status.
- Use another Switch node to loop until
status == "completed".
Performance Note: A 5–6 minute video took ~30 minutes to generate, with the wait node running 6–8 times (30 seconds each). The system is fully automated—you can start it and walk away.
Updating Google Sheets with Final Output
When video generation succeeds:
- Add a Google Sheets node using “Update Row in Sheet.”
- Set sheet and map:
- Row Number:
={{ $json.row_number }} - task_status: “done”
- output:
={{ $json.video_url }}(the MP4 link)
- Row Number:
Error Handling and Logging
To catch failures:
- Duplicate the “Update Row” node.
- Connect it to the Fallback output of your Switch nodes.
- Set:
- task_status: “error”
- output:
={{ $json.error.message }}
This logs the exact error from Wavespeed (e.g., invalid voice ID, image too large), making debugging easy.
Cost Analysis and Optimization
The system includes an estimated_cost column in Google Sheets. Based on testing:
| Model | Cost for 10-Minute Video | Verdict |
|---|---|---|
| Infinity Talk (via Wavespeed) | ~$0.60 | Best value |
| Competing Models (unnamed) | Significantly higher | Not recommended |
Costs scale with:
- Audio length (11 Labs)
- Video resolution (480p vs. 720p)
- Model usage (Infinity Talk)
