Automate face swapping for GIFs with Fal.run AI and Google Services

This workflow allows you to automatically swap faces in animated GIFs using AI, without writing a single line of code.

By simply inserting the URL of a face image and a GIF into a Google Sheet, the automation takes care of everything: it sends the data to AI platform, monitors the processing status, retrieves the final face-swapped GIF, uploads it to Google Drive, and updates the Google Sheet with the result.

This solution is perfect for content creators, marketers, or developers looking to integrate AI-powered GIF editing into their workflows in a fast and scalable way.

Whether used manually or on a scheduled basis, the workflow turns a tedious creative task into a fully automated pipeline.

This workflow automates GIF face-swapping by integrating Google Sheets for input/output and Fal.run for AI processing, ensuring seamless execution via scheduled or manual triggers.

How It Works

1. Trigger:

   • The workflow can be triggered manually ("When clicking ‘Test workflow’") or automatically via a scheduled trigger ("Schedule Trigger") set to run at intervals (e.g., every 5 minutes).

2. Data Retrieval:

   • The "Google Sheets" node fetches data from a predefined Google Sheet, which includes two columns:
     • FACE IMAGE: URL of the face image to swap.
     • GIF IMAGE: URL of the target GIF.

3. API Request:

   • The "Set data" node formats the retrieved URLs into variables (face_image and gif_image).
   • The "Create Image" node sends a POST request to the Fal.run API (easel-gifswap endpoint) with these URLs to initiate the face-swapping process. The API returns a request_id.

4. Status Check:

   • The "Wait 60 sec." node pauses execution for 60 seconds to allow processing time.
   • The "Get status" node queries the Fal.run API using the request_id to check if the task is COMPLETED.
   • If completed, the "Get Url image" node retrieves the final GIF URL.

5. Output Handling:

   • The "Upload Image" node saves the resulting GIF to Google Drive.
   • The "Update result" node writes the output GIF URL back to the Google Sheet under the RESULT column.

Set Up Steps

1. Prepare Google Sheet:

   • Create a Google Sheet with columns: FACE IMAGE, GIF IMAGE, and RESULT.
   • Populate the first two columns with image URLs. Leave RESULT empty for the workflow to fill.

2. Configure API Key:

   • Sign up to obtain an API key.
   • In the "Create Image" node, set HTTP header authentication:
     • Name: Authorization
     • Value: Key YOURAPIKEY

3. Schedule Execution:

   • Link the "Schedule Trigger" node to run periodically (e.g., every 5 minutes) or trigger manually for testing.

4. Test and Deploy:

   • Run the workflow to verify face-swapping functionality.
   • Monitor the Google Sheet for the RESULT column updates with the processed GIF URL.
