AI character swap
How the AI-side workflow works, step by step.
Bulin AI is a character-swap video generator built around the Bulin 47 freestyle clip. You upload a single photo of a person, choose the freestyle template, and the tool rebuilds the performance with your character as the lead — same choreography, same tempo, same camera, same sound. Nothing to film, no timeline to edit.
- Add your character photo
A clear, front-facing shot works best. One image is all the tool needs.
- Pick a template
The Bulin 47 freestyle comes loaded, with the motion reference already fixed. More templates are one click away.
- Generate and review
Watch the result, adjust the instructions if you want a different energy, then download and post.
A front-facing, well-lit photo of one person with the face unobstructed works best. Group shots, heavy shadows and very small faces render poorly.
