Optional: Background Image/Video Behind Avatar

• Open SETUP HEYGEN node and set parameter 'has_background_video' to true
• Open SETUP HEYGEN node and replace video URL in parameter 'background_video_url'
• Recommendation: Only enable after the basic workflow is operational, i.e. you can make avatar videos without a background

Tips & Tricks

• Perplexity API account must have billing funded
• HeyGen API requires paid plan
• Make sure you copied your avatar ID correctly (not the group avatar ID)
• If your script is long, it takes more time for your video to finish
• While testing:
  • Enable only 1 social platform and deactivate the rest
  • Update AI writer prompt to return a 5-second script instead of 30 seconds to reduce processing time
• Go to HeyGen and check that your avatar video is being processed
• After the workflow finishes, check your social media account for the final post
• If successful, enable another social media node and continue testing
