Generate AI viral videos with Seedance and upload to TikTok, YouTube & Instagram

![Workflow Screenshot](https://www.dr-firas.com/seedanceII.png) # Generate AI videos with Seedance & Blotato, upload to TikTok, YouTube & Instagram ### Who is this for? This template is ideal for creators, content marketers, social media managers, and AI enthusiasts who want to automate the production of short-form, visually captivating videos for platforms like TikTok, YouTube Shorts, and Instagram Reels — all without manual editing or publishing. ### What problem is this workflow solving? Creating engaging videos requires: - Generating creative ideas - Writing detailed scene prompts - Producing realistic video clips and sound effects - Editing and stitching the final video - Publishing across multiple platforms This workflow automates the entire process, saving hours of manual work and ensuring consistent, AI-driven content output ready for social distribution. ### What this workflow does This end-to-end AI video automation workflow: 1. **Generates a creative idea** using OpenAI and LangChain 2. **Creates detailed video prompts** with Seedance AI 3. **Generates video clips** via Wavespeed AI 4. **Generates sound effects** with Fal AI 5. **Stitches the final video** using Fal AI’s ffmpeg API 6. **Logs metadata and video links** to Google Sheets 7. **Uploads the video to Blotato** 8. **Auto-publishes to TikTok, YouTube, Instagram, and other platforms** ### Setup 1. Add your **OpenAI API key** in the LLM nodes 2. Set up **Seedance and Wavespeed AI credentials** for video prompt and clip generation 3. Add your **Fal AI API key** for sound and stitching steps 4. Connect your **Google Sheets account** for tracking ideas and outputs 5. Set your **Blotato API key** and fill in the platform account IDs in the `Assign Social Media IDs` node 6. Adjust the **Schedule Trigger** to control when the automation runs ### How to customize this workflow to your needs - **Change the AI prompts** to target your niche (e.g., ASMR, produc
