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:

  1. Retrieved and stored (Google Drive upload).
  2. Optimized with an AI-generated YouTube title for better SEO.
  3. 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:

  1. 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
  2. Status Monitoring: Continuously checks the processing status every 60 seconds until the video generation is completed
  3. Title Generation: Uses OpenAI's GPT model to create an SEO-optimized YouTube title based on the original prompt
  4. File Handling: Downloads the generated video and uploads it to Google Drive for storage
  5. 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)
