🎬 Create & share lip-synced avatar videos with Infinitalk AI & upload to TikTok/YouTube

💡 Pro Tip — Since TikTok doesn’t have a public API, getting data usually means fragile HTTP scraping. ScraperNode is a community node that gives you clean JSON for TikTok profiles, videos, and comments — drop it into your workflow and skip the parsing.
Description
This workflow automates the process of generating and publishing a talking avatar video. It takes a video and an audio file as inputs, then uses the Infinitalk API to create a lip-synced avatar that naturally matches the audio. Once generated, the video is:
- Retrieved and stored (Google Drive upload).
- Optimized with an AI-generated YouTube title for better SEO.
- Automatically uploaded to YouTube and TikTok via the Upload-Post API.
Key Advantages
- ✅ Full Automation: From video generation to social media publishing, everything is handled automatically.
- ✅ AI-Powered Content Optimization: Uses GPT-based AI to create SEO-friendly and catchy YouTube titles, increasing reach and engagement.
- ✅ Multi-Platform Publishing: Videos are instantly shared across YouTube and TikTok, saving time on manual uploads.
- ✅ Seamless Storage Integration: Generated videos are saved to Google Drive for archiving or reuse.
- ✅ Scalable Workflow: Can be reused for multiple videos, podcasts, tutorials, or marketing clips with minimal effort.
- ✅ Natural Lip-Sync: Infinitalk API ensures avatars sync realistically with audio, creating professional-looking videos.
- ✅ Customizable: Resolution, number of frames, and acceleration options can be adjusted for different needs (e.g., faster processing vs. higher quality).
How It Works
The process begins with a form submission where users provide a video URL (for the avatar), an audio URL (for lip-sync), and a text prompt describing the video content. The system then:
- Video Generation: Sends the inputs to Fal.ai’s Infinitalk API which creates a talking avatar video where the character lip-syncs to the provided audio with natural facial expressions
- Status Monitoring: Continuously checks the processing status every 60 seconds until the video generation is completed
- Title Generation: Uses OpenAI’s GPT model to create an SEO-optimized YouTube title based on the original prompt
- File Handling: Downloads the generated video and uploads it to Google Drive for storage
- Multi-Platform Distribution: Automatically publishes the video to both YouTube and TikTok using the Upload-Post service
The workflow includes conditional logic to ensure each step executes in the correct order and only proceeds when previous operations are successful.
Set Up Steps
Step 1: Configure Fal.ai API
- Create an account at Fai AI and obtain your API key
- In the “Create Video” node, set up Header Authentication with:
- Name: “Authorization”
- Value: “Key YOURAPIKEY”
Step 2: Configure Upload-Post Service
- Get your API key from Upload-Post Manage Api Keys
- Set up the authentication header in both upload nodes:
- Name: Authorization
- Value: Apikey YOUR_API_KEY_HERE
- Create social media profiles in Upload-Post and replace “YOUR_USERNAME” in the upload nodes with your profile name
- Note: Free plan supports all platforms except TikTok (requires paid upgrade)
