An AI Agent generates a unique ASMR video concept and saves the Idea, Caption, Environment, and Sound details into your first Google Sheet. ### Scene Prompting A second AI Agent takes the approved idea from the sheet and creates three detailed, cinematic scene prompts designed for text-to-video AI. ### Video & Audio Generation The workflow makes parallel API calls to Fal.ai: - Generates a video clip for each of the three scenes - Generates a single, corresponding ASMR audio track - Continuously polls Fal.ai until assets are ready ### Merging & Finalizing Once all assets are generated, it sends a request to Fal.ai's FFMPEG API to stitch the video clips and audio track into one final video. ### Logging & Publishing The final video URL is saved to your second Google Sheet. The workflow then uploads this video to Blotato and publishes it to your specified Instagram and TikTok accounts. ## 🎨 Customization Guide ### Content Type Customization To adapt this workflow for different content types: 1. **Modify the AI prompts**: - In `AI Agent: Generate Creative Video Idea`, update the prompt to match your content style - Adjust the systemMessage to reflect your brand voice and content guidelines 2. **Change video parameters**: - In `Generate Video Clips (Wavespeed AI)`, modify: - `duration`: Video length (default: 10 seconds) - `aspect_ratio`: Change from "9:16" to "16:9" for horizontal videos 3. **Adjust audio generation**: - In `Generate ASMR Sound (Fal AI)`, update the prompt for different audio styles - Modify `cfg_strength` (1-10) for more/less adherence to prompt ### Platform-Specific Adjustments 1. **Instagram-specific**: - Maximum video duration: 90 seconds for Reels - Optimal hashtag count: 5-10 2. **TikTok-specific**: - Maximum video duration: 10 minutes - Optimal hashtag count: 3-5 - In `Publish to TikTok` node, adjust privacy settings as needed ### Scheduling Options Modify the `Trigger: Start Daily Content Generation` node: - Change from daily to hourly, weekly, or specific times - Add multiple triggers for different time zones - Use cron expressions for complex schedules ### Error Handling Add error handling nodes: - Connect error outputs to notification systems - Log failed attempts to a separate Google Sheet - Implement retry logic for API failures ## 🎯 Perfect For - **Content Creators** looking to scale their output with minimal effort - **Digital Marketers** seeking a consistent stream of engaging, trend-based content - **Brands** wanting to build a strong presence on short-form video platforms - **Automation Enthusiasts** building content-driven businesses ## 🚀 Getting Started 1.
