# AI Character Swap Workflow Guide

> Step-by-step browser workflow for AI character swaps and motion transfer

A practical guide detailing how to replace people in videos using web-based AI tools instead of local video-to-video setups. It explains how to extract a keyframe, generate a matching character in identical pose, and drive motion via Kling 2.6 or Wan 2.2.

## How it works

Workflow: (1) Find a reference video with a single character, upper/full body visible (record your own or pull from TikTok/YouTube). (2) Screenshot the first frame and edit it with an image model (Nano Banana Pro or Flux 2 on Krea) — keep the character's position identical, e.g. "replace the man in image 1 with the woman in image 2 in exactly the same pose". (3) Take reference video + new first frame to Kling 2.6 Motion Control (on kling.ai, Krea, or Fal), leave the prompt empty; on Kling check "character orientation matches video". (4) Change voice with ElevenLabs voice changer when age/ethnicity/gender changes. Alternatives: Wan 2.2 Animate (Move = new character AND background; Replace = swap character only, keep scene; needs a "clean" start frame) on Krea/Fal; Luma Ray 3 Modify (10s) and Runway Gen-4 Aleph (5s) for broader editing but weaker lip sync. Pro tip: Kling Motion Control can handle complex full-body movement — under-explored.

## What it is for

- Swap actors in existing social clips with AI-generated avatars
- Transfer motion from a reference video to a custom digital character
- Change the character's voice to match new demographic traits using AI voice changers

## Key points

- Select or record a clean single-character reference clip with full or upper body visible
- Swap the character on the first frame using image models like Flux or Nano Banana Pro while preserving pose
- Run motion transfer in Kling 2.6 Motion Control with an empty prompt and orientation matching enabled
- Use Wan 2.2 Animate, Luma Ray 3 Modify, or Runway Gen-4 Aleph as alternative transfer engines
- Alter original dialogue audio using ElevenLabs voice-to-voice tools
