💡 Pro Tip — Since TikTok doesn’t have a public API, getting data usually means fragile HTTP scraping. ScraperNode is a community node that gives you clean JSON for TikTok profiles, videos, and comments — drop it into your workflow and skip the parsing.

Description

Convert Viral Videos into AI Avatar Swaps and Publish on TikTok with Blotato

Who is this for?

This workflow is designed for content creators, agencies, influencers, and automation builders who want to transform viral videos into personalized avatar-based edits — and automatically publish them on TikTok (and other platforms) without manual editing or video software.

What problem is this workflow solving?

Replacing a character in a video, transforming the voice, merging audio/video, and publishing to social networks typically requires multiple tools, editing skills, and a lot of time.
This workflow automates the entire pipeline end-to-end:

• No manual video editing
• No audio processing
• No API debugging
• No uploading/publishing hassles

It’s a full AI-powered transformation system that produces ready-to-post content in minutes.

What this workflow does

This workflow receives an avatar image + a viral video URL and automatically:

1. Extracts the audio using Replicate
2. Replaces the character in the video using FAL WAN Replace
3. Transforms the voice using FAL Chatterbox Speech-to-Speech
4. Merges the new video and audio using FAL FFmpeg
5. Saves results to Google Sheets for tracking
6. Publishes the final video to TikTok via Blotato (and optionally to Instagram, Facebook, LinkedIn, X, and YouTube)
7. Sends a confirmation message when publishing is complete

Everything runs automatically, in parallel, for maximum speed.
