Provides AI filmmakers and commercial ad creators with a practical, step-by-step pipeline for character consistency, environment swapping, and product replacement using Higgsfield Genjutsu.
What this lesson covers
Rourke presents a four-step workflow using Higgsfield Genjutsu to swap characters, backgrounds, and handheld props in video footage. He demonstrates how to generate multi-view reference sheets, prompt background locations via Claude and Midjourney, and execute product replacements for video ad variations.

Shoot source footage with a steady camera while keeping the subject's face clearly visible and holding props clearly in front of the camera.
- 02:24 ↗
Generate multi-angle character sheets showing front, side, back, and close-up views to provide visual reference for video replacement models.
- 03:06 ↗
Use GPT Image 2 inside Higgsfield to generate character sheets that avoid plastic skin textures and retain realistic details.
- 05:48 ↗
Use Claude to draft Midjourney prompts inspired by reference images to avoid direct copyright infringement when re-creating locations.
- 07:45 ↗
Compile multi-angle product screenshots into prop reference sheets to ensure high-fidelity prop replacements in video clips.
Workflow outlined in the video
- Film source video footage using a steady camera, ensuring clear face visibility and distinct handheld prop placement.
- Take a still screenshot of the subject's face from the source video to serve as a reference image.
- Generate a 4-view character sheet in Higgsfield using GPT Image 2 by specifying outfit and character details.
- Upload the source video and character sheet into Higgsfield Genjutsu with instructions to replace the character's outfit while keeping motion identical.
- Upload a location reference image to Claude to generate an inspired Midjourney prompt, then render the new background image.
- Upload the character-swapped video and new background image into Higgsfield Genjutsu to perform the location swap.
- Gather multi-angle product images, generate a product sheet in Higgsfield, and use Genjutsu to replace handheld props in the scene.
