Colorize & Animate Old Photos with AI, Auto-Publish to Social Media

Overview

This workflow transforms old, black-and-white or sepia photographs into vibrant, animated videos using AI, then automatically saves the result to Google Drive and publishes it across multiple social media platforms. It combines image colorization (FLUX Kontext), AI video animation (Kling Video AI), and cross-platform social media posting in a single automated pipeline.

Perfect for historians, archivists, family history enthusiasts, or content creators looking to breathe new life into vintage imagery. The workflow handles the entire process from user upload through final distribution, making it easy to create engaging social media content from historical photos.

Workflow Steps

1. Photo Upload Form (Form Trigger — No auth) — Displays a web form where users upload an old photo and optionally provide a custom animation description. The form is accessible at /form/animate-photo-form.

2. Upload Image to imgbb (HTTP Request — API Key auth via query parameter) — Uploads the submitted photo to imgbb.com's free image hosting service. Uses multipart form-data to send the binary image file and an API key (configured in the node's body parameters).

3. Colorize Image (HTTP Request — Header Auth) — Sends the uploaded image URL to FLUX Kontext (fal.ai) with a prompt to colorize, denoise, and enhance the photo. Uses HTTP Header authentication with a custom API key.

4. Wait for Colorization (Wait — No auth) — Pauses execution to allow the colorization process to complete. Uses a webhook-based wait mechanism.

5. Check Colorization Status (HTTP Request — Header Auth) — Polls the FLUX Kontext queue status endpoint to check if colorization is complete. Uses the request ID from step 3.

6. Colorization Completed? (IF — No auth) — Evaluates whether the status returned is "COMPLETED". If yes, proceeds to fetch the result; if not, loops back to the Wait node for continued polling.

7. Get Colorized Image (HTTP Request — Header Auth) — Retrieves the final colorized image URL from FLUX Kontext once processing is complete.

8. Animate Image (HTTP Request — Header Auth) — Sends the colorized image to Kling Video AI (fal.ai) with an animation prompt. Uses the user's optional custom description, or defaults to a natural movement prompt. Configures 5-second video duration at standard quality.

9. Wait for Animation (Wait — No auth) — Pauses for 60 seconds to allow video generation to progress before checking status.

10. Check Animation Status (HTTP Request — Header Auth) — Polls the Kling Video queue status endpoint using the request ID from step 8.

11. Animation Completed? (IF — No auth) — Checks if animation status is "COMPLETED". If yes, fetches the video; if not, loops back to the Wait node.

12. Get Animated Video (HTTP Request — Header Auth) — Retrieves the final animated video URL from Kling Video AI.

13. Download Video (HTTP Request — No auth) — Downloads the video file from the URL returned in step 12.

14. Upload to Google Drive (Google Drive — OAuth2) — Saves the downloaded video to the user's Google Drive root folder with a timestamped filename (e.g., animated-photo-20250101-120000.mp4).

15. Final Results (Set — No auth) — Compiles a structured output containing success flag, message, colorized image URL, animated video URL, Google Drive link, and processing timestamp.

16. Upload Post (Upload Post — API Key auth) — Automatically publishes the animated video to Instagram (as Reels), X (Twitter), YouTube, and Facebook using the upload-post API service.

Setup Instructions

Required Accounts & Credentials

1. imgbb.com — Free image hosting. Sign up at imgbb.com and get your API key from the account dashboard.

2. FAL.AI — AI processing platform. Create an account at fal.ai and generate an API key. This key is used for both FLUX Kontext (colorization) and Kling Video (animation).

3. Google Drive — Connect your Google account via OAuth2 in n8n. You'll need a Google Cloud project with the Drive API enabled.

4. Upload Post API — Service for cross-platform social media posting. Sign up at uploadpost.com and obtain your API credentials.

Configuration Steps

1. In the Upload Image to imgbb node, replace generate_token_and_add in the body parameters with your actual imgbb API key.
2. In all HTTP Request nodes using Header Auth, configure the credential with your FAL.AI API key (typically as Authorization: Key YOUR_API_KEY).
3. In the Upload to Google Drive node, authenticate with your Google account.
4. In the Upload Post node, replace ADD_UPLOAD_POST_USER with your Upload Post API user identifier and configure the credential.
