Transform Videos with FAL AI Avatar Swaps & Voice and Publish to TikTok with Blotato

1. Workflow Overview

This workflow automates the transformation of viral videos by swapping the original character’s face with a custom AI avatar and changing the voice, then publishes the final video to TikTok via Blotato. It is designed for content creators who want to quickly generate engaging AI-enhanced videos and track their outputs.

The workflow is logically divided into the following blocks:

1.1 Input Reception: Receives avatar images and video URLs via Telegram messages.
1.2 Audio and Video Extraction: Separates the audio from the original video for independent processing.
1.3 Parallel Transformation: Simultaneously replaces the face in the video and transforms the voice audio using FAL AI APIs.
1.4 Merging and Finalization: Combines the transformed video and audio into a single output file.
1.5 Publishing and Tracking: Uploads the final video to Blotato for TikTok publishing and logs URLs to Google Sheets.
1.6 Caption Generation: Transcribes audio and generates engaging TikTok captions using GPT-4.

2. Block-by-Block Analysis
