Your Bulin 47 AI video, from selfie to post
Everything between "I want to do the Bulin 47 trend" and your face in Kevin Wai's freestyle on your profile: the photo to use, the settings, what to fix when it looks wrong, and how to keep the sound.
Updated
What you need
- One clear photo of one person
- 10 or 22 credits, depending on the quality
- A phone or computer with a browser
- About ten minutes, mostly waiting
- 1
Take or pick the right photo
Stand facing the camera in daylight, phone at eye level, upper body in frame. Take off sunglasses and caps: your face replaces the performer's, so it has to be clear. Skip beauty filters: the AI copies whatever it sees, including blur.
- 2
Open the studio and add it
Use the studio on the home page. HEIC from an iPhone is fine. The photo stays private and is deleted after 7 days.
- 3
Pick the quality
480p looks fine on a phone feed; 720p is sharper if you plan to zoom or repost to YouTube. Your outfit comes from the photo.
- 4
Make it and wait
Tick the permission box and press the button. The render takes 3 to 10 minutes. Close the tab if you like; the video waits in My videos.
- 5
Download both files and post
Save the version with sound and the silent copy. Post the one with sound; if the app mutes it, upload the silent copy and add the Bulin 47 sound from the app.
What changes in your Bulin 47 video, and what stays
The AI swaps one person: the performer facing the camera in Kevin Wai's freestyle. Everything else comes from the original Madrid clip.
Becomes yours
- Your face, hair and skin tone on the performer, for all of the clip
- Your outfit, taken from the upper body in your photo
- Your build, so a pet or a drawing works too
Stays from the original
- Kevin Wai with the portable speaker and the phone, his back to the camera
- The crowd, the security staff and the red-lit restaurant entrance
- The handheld camera move and every gesture of the freestyle
- The original dembow sound, added back after the render
The speaker is already playing
Make my recastWhen it looks off: quick fixes
| What you see | Usual cause | Try this |
|---|---|---|
| The face does not look like me | Dark, side-on or filtered photo | Retake facing a window, no filter |
| My clothes changed | Face-only crop, nothing to copy | Use a photo that shows your top |
| The mouth moves when nobody raps | Rare; the copy drifted | Try another photo, facing the camera |
| TikTok muted my video | Copyright match on the audio | Post the silent copy, add the sound in-app |
| The render failed | Photo refused by the safety check, or a provider error | Credits come back automatically; try a different photo |
Other ways people make it
Tutorials on TikTok mostly show three routes. Here is what each one asks of you, as of October 2026.
| Route | You prepare | What comes out |
|---|---|---|
| CapCut template | A video of yourself | Effects on your own footage, not the Madrid clip |
| Prompt tools (Dreamina, Seedance, others) | The original clip, a photo and a written prompt | Depends on your prompt and trimming |
| This site | One photo | The Madrid clip with you in it, original sound added back |
