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.

n8n Form Triggered OpenAI Video Generation Workflow

This n8n workflow provides a powerful automation for generating video content using OpenAI's capabilities, triggered by a simple form submission. It allows users to input a prompt via a web form, which then gets processed by OpenAI to potentially generate video ideas or scripts, and then proceeds with further actions based on a conditional check.

What it does

This workflow automates the following steps:

  1. Listens for Form Submissions: The workflow is initiated when a user submits data through an n8n form.
  2. Processes Input with OpenAI: The submitted data is sent to OpenAI, likely to generate creative content such as video ideas, scripts, or descriptions based on the user's prompt.
  3. Conditional Logic: An "If" node evaluates the output from OpenAI. This allows for branching logic, enabling different actions based on whether certain conditions are met (e.g., if the generated content is suitable, or if a specific keyword is present).
  4. Waits (Conditional): If the condition in the "If" node is met (TRUE branch), the workflow pauses for a specified duration using a "Wait" node. This could be used to simulate a processing time or to introduce a delay before the next steps.
  5. HTTP Request (Conditional): Following the wait, an HTTP Request is made. This could be used to interact with a video generation API (like Sora 2, as hinted by the directory name), upload content, or trigger another external service.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance to host and execute the workflow.
  • OpenAI API Key: An API key for OpenAI to utilize its language and content generation models. This will need to be configured in the OpenAI node's credentials.
  • External Video Generation Platform (Optional but likely): While not explicitly configured in the provided JSON, the HTTP Request node strongly suggests integration with an external video generation service (e.g., Sora 2, or similar platforms for AI video creation) that accepts API calls. You will need an account and API access for such a service.
  • TikTok Account (Optional but likely): The directory name suggests auto-publishing to TikTok. This would require a TikTok integration, likely via another HTTP Request or a dedicated n8n node, which is not fully detailed in the provided JSON but would be a logical extension.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • OpenAI Node: Add your OpenAI API key as a credential for the "OpenAI" node.
  3. Configure Form Trigger:
    • Activate the "On form submission" trigger node. You will get a unique URL for your form.
    • Customize the form fields as needed for your video prompt input.
  4. Configure OpenAI Node:
    • Adjust the model and prompt in the "OpenAI" node to suit your video generation requirements. You will likely reference the input from the "On form submission" node.
  5. Configure If Node:
    • Set up the conditions in the "If" node based on the expected output from OpenAI. For example, you might check for specific keywords, sentiment, or a flag indicating successful content generation.
  6. Configure Wait Node:
    • Adjust the duration of the "Wait" node if needed.
  7. Configure HTTP Request Node:
    • Crucially: Configure the "HTTP Request" node with the correct URL, headers (including API keys/tokens), and body for your chosen video generation API. This is where the actual video creation or publishing action would be initiated. You will likely pass the generated content from OpenAI to this request.
  8. Activate the Workflow: Once configured, activate the workflow.
  9. Submit the Form: Access the form URL from the "On form submission" node and submit a prompt to trigger the workflow.

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
