        "content": "# What does this workflow do?\n\n## Description\n\nThis AI Avatar Viral News system turns any URL\u2014a news article, blog post, or even an n8n workflow page\u2014into a short, vertical talking-head AI video that explains the content for you (no filming or editing required). It uses Gemini to fetch and summarize the page, writes a punchy script and captions, then generates the video with HeyGen. Finally, it sends the MP4 to **Upload-Post** to publish or schedule across your social profiles.\n\n### The 4 video types we generate\n\n**Free (zero cost, full free trial of APIs):**\n1) **Split-screen (vertical) with background video**: top half shows an auto-scroll capture of the article/blog/workflow; bottom half shows your avatar speaking and gesturing.\n2) **Split-screen (vertical) with static image**: same layout, but instead of a background video, we use a single static image (e.g., the article\u2019s hero image or a screenshot).\n\n**Paid heygen api (background removal):**\n3) **Cut-out avatar over background video**: your avatar is cleanly cut out and overlaid on top of a background video.\n4) **Cut-out avatar over static image**: your avatar is cleanly cut out and overlaid on a single static image.\n\n> Notes:\n> - Free/Trial modes use split-screen (no background removal).\n> - Paid modes use background removal for a clean overlay (depends on HeyGen plan and API availability).\n\n### HeyGen rendering modes\n- **Free / Trial (no background removal):** split-screen look (avatar on the lower half, background video or static image on the upper half).\n- **Paid API (with background removal):** clean cut-out avatar over a background video or a static image. Enable by setting `background_removal: true` in the **Set Input Vars** node (requires a paid HeyGen API plan).\n\n## Overview\n\n1. **Manual trigger**\n\n2. **AI agent: fetch webpage & generate script**  \n   - The agent grabs the target page and produces a concise, 30\u201345s script.  \n   - Generates platform-optimized captions/descriptions.\n\n3. **Create avatar video (HeyGen)**  \n   - Call the HeyGen API with your `avatar_id` and `voice_id`.  \n   - Choose layout/background:\n     - **Free / Trial:** split-screen vertical.\n       - **Background as video:** set `has_background_video: true` and provide `background_video_url`.\n       - **Background as static image:** set `has_background_image: true` and provide `background_image_url`.\n     - **Paid:** background removal overlay.\n       - **Overlay on video:** set `background_removal: true` and `background_video_url`.\n       - **Overlay on static image:** set `background_removal: true` and `background_image_url`.\n\n4. **Get video**  \n   - Poll HeyGen until the job completes, then download the final MP4.  \n   - Upload the resulting video file to **Upload-Post**.\n\n5. **Human review / approval**  \n   - A human reviews the video, title, and captions. Approve to continue, or request changes and loop back to steps 2\u20134.\n\n6. **Publish to social media via Upload-Post**  \n   - Connect your social profiles in **Upload-Post**.  \n   - Pick platforms (e.g., TikTok, Instagram, YouTube, X, Facebook, etc.).  \n   - Publish immediately or schedule for later."
