1.1 Workflow description

Title
Generate AI promo videos for products with GPT-4o, Fal.ai & human supervision
Workflow name
Generate AI promo videos for products with GPT-4o, Fal.ai & human supervision

Generate AI video clips to promote products, services or events on social media. Use gotoHuman as an interface to control and supervise each step of the workflow to create content that's actually worth posting.

How it works

gotoHuman will show the workflow steps that need approval or input in its' inbox and notify you via email or Slack.

  1. We choose from different topics for our post suggested by AI
  2. We select the image style, a product to show, and review an AI-generated tag line
  3. We use Fal.ai to generate an image that serves as a reference image for our video clip. And we use Cloudinary to add an overlay for the tag line. We review the image in gotoHuman and can iterate on it by retrying or even changing the prompt.
  4. We review the video clip that's generated with Fal.ai based on the approved image and can, again, retry or reprompt.

How to set up

  1. Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing)
  2. Follow the instructions shown along the workflow and in the incl. video guide. You mainly need to
  • set up your credentials for gotoHuman, OpenAI, Fal.ai and Cloudinary
  • in gotoHuman, select and create the pre-built review template "Promo video agent" or import these IDs: Z7V1jyImY1pho9eY039R,0GBaOCWd27tqV562kkCL,E2wlCVPWmk2UnLHVt4uu,DitPdbIapS4rBxBTIYGt,Z2T7nFwkXVFQlD6z50eV
  • select these templates in the gotoHuman nodes
  • do a quick setup for Cloudinary

Requirements

You need accounts for

  • gotoHuman (human supervision)
  • OpenAI (ideation)
  • Fal.ai (image/video generation)
  • Cloudinary (text overlay)

How to customize

  • Adjust/Replace the workflow triggers as needed
  • Change the prompt in the topics generation node
  • Replace the product image URLs used in the "gotoHuman - Content" node
  • Adjust the available styles for image generation in the gotoHuman review template and the prompts they link to in the "Set Initial Image Prompt" node
  • Adjust the prompt used for video generation in the "Set Initial Video Prompt" node
  • If you want to use a different service/model for image and video generation, replace the nodes related to Fal.ai.
  • Also, if you do not need a text overlay, remove the Cloudinary nodes.

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/7196/7196.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
