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 YOUR_API_KEY.

  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.
