Generate Funny AI Videos with Sora 2 and Auto-Publish to TikTok

This automation creates a fully integrated pipeline to generate AI-powered videos, store them, and publish them on TikTok — all automatically. It connects OpenAI Sora 2, and Postiz (for TikTok publishing) to streamline content creation. --- Key Benefits ✅ Full Automation – From text prompt to TikTok upload, everything happens automatically with no manual intervention once set up. ✅ Centralized Control – Google Sheets acts as a simple dashboard to manage prompts, durations, and generated results. ✅ AI-Powered Creativity – Uses OpenAI Sora 2 for realistic video generation and GPT-5 for optimized titles. ✅ Social Media Integration – Seamlessly posts videos to TikTok via Postiz, ready for your audience. ✅ Scalable & Customizable – Can easily be extended to other platforms like YouTube, Instagram, or LinkedIn. ✅ Time-Saving – Eliminates repetitive steps like manual video uploads or caption writing. --- How it works This workflow automates the end-to-end process of generating AI videos and publishing them to TikTok. It is triggered either manually or on a recurring schedule. 1. Trigger & Data Fetch: The workflow starts by checking a specified Form for new entries. It looks for rows where a video has been requested (a "PROMPT" is filled) but not yet generated (the "VIDEO" column is empty). 2. AI Video Generation: For each new prompt found, the workflow sends a request to the Fal.ai Sora 2 model to generate a video. It then enters a polling loop, repeatedly checking the status of the generation request every 60 seconds until the video is "COMPLETED". 3. Post-Processing & Upload: Once the video is ready, the workflow performs several actions in parallel: Fetch Video & Store: It retrieves the final video URL, downloads the video file Generate Title: It uses the OpenAI GPT-4o-mini model to analyze the original prompt and generate an optimized, engaging title for the video. Publish to TikTok: The video file is uploaded to Postiz, a social media scheduling tool, which then automatically publishes it to a connected TikTok channel, using the AI-generated title as the post's caption. --- Set up steps To make this workflow functional, you need to complete the following configuration steps: 1. Prepare the Google Sheet: Create a Form with at least "PROMPT", "DURATION", and "VIDEO" fields. 2. Configure Fal.ai for Video Generation: Create an account at Fal.ai and obtain your API key. In both the "Create Video" and "Get status" HTTP Request nodes, set up the "Header Auth" credential. Set the Name to Authorization and the Value to Key YOURAPIKEY. 3. Set up TikTok Publishing via Postiz: Create an account on Postiz and connect your TikTok account to get a Channel ID. Obtain your Postiz API key. In the "Upload Video to Postiz" and "TikTok" (Postiz) nodes, configure the API credentials. In the "TikTok" node, replace the placeholder "XXX" in the integrationId field with your actual TikTok Channel ID from Postiz. 4. (Optional) Configure AI Title Generation: The "Generate title" node uses OpenAI. Ensure you have valid OpenAI API credentials configured in n8n for this node to work. --- Need help customizing?
