Why we ask
Putting someone’s face in a video without their OK can break privacy and image-rights laws, and that responsibility is yours. So you confirm three things: you are the person or have their OK, they are an adult, and they are not a celebrity or a politician. We keep the time you confirmed with the request.

Bulin 47 AI videos recast the viral clip of Dominican artist Bulin 47 freestyling over a fan's speaker outside a restaurant in Madrid. Here you upload one photo, and the AI rebuilds the 15 seconds after the camera finds him, with you as the performer. The movement comes from the real footage and the original sound is added back afterwards, so your mouth only raps where Bulin 47 actually raps. A recast costs 10 credits at 480p or 22 at 720p and usually takes 3 to 10 minutes.

Your 15 seconds
What happens in your clip
The recast always covers the same stretch of the original, from the second the camera finds the performer.
| Seconds | What you do |
|---|---|
| 0 to 7 s | Rap straight to the phone, hands moving on every line, while the crowd starts filming. |
| 7 to 12 s | Turn to the fan with the speaker, lean in, rub your head and laugh while he takes the vocals. |
| 12 to 15 s | Look down at the phone, smiling, as the beat keeps going. |
10 credits at 480p, 22 at 720p.
Who can step in
Anyone who can hold the beat
You
A front-facing selfie with your shoulders in frame works best.
A friend
Only with their OK. Adults only; no celebrities or public figures.
Your pet
Dogs and cats can take the spot too. Results vary more than with people, and they keep their fur: no shirt added.
A drawing
Your own character or a cartoon of yourself, as long as you own the art.

Photo checklist
What makes a recast look like you
- Face the camera, eyes visible
- Daylight or a bright room
- Head and shoulders, ideally your top too
- One person in the photo
- Sunglasses or a cap hiding your face
- Group photos
- Heavy filters or beauty effects
- Tiny or blurry images
Honest limits: the mouth follows Bulin 47's mouth, not your voice, so it will not match words you sing yourself. Faces in the crowd can wobble for a frame. Jewelry or a watch from the clip sometimes stays.
About the sound
Original audio, laid back on after
The AI renders a silent picture. We then put the clip's own audio back under it, so the dembow beat and both voices sit exactly where they were. Some apps detect the track and mute it; for those, post the silent copy and pick the trending Bulin 47 sound inside the app.

FAQ
Questions people ask
Is there a free Bulin 47 AI video?
A preview, yes: each Google account can make one free 5-second preview at 480p with the original sound, watermarked and not downloadable. The full 15-second video is 10 credits at 480p (the $9.99 Single pack) or 22 at 720p. If a render fails, the credits go back automatically.
Can I keep my own clothes?
Yes: face, hair and outfit all come from your photo. Show your upper body, not just a face crop, so there is an outfit to copy.
Why does the mouth not match my voice?
Because there is no new voice. The mouth copies Bulin 47's mouth in the real footage, and the real audio is added afterwards. During the part where the fan sings, the performer stays quiet, just like in the clip.
How long until my video is ready?
Usually 3 to 10 minutes. You can leave the page. Finished recasts wait in My videos.
Can I use a photo of a celebrity?
No. Use your own photo or one of an adult who agreed. Photos of public figures, minors or anyone without consent are not allowed.
Is this the official Bulin 47 app?
No. It is an independent fan tool with no tie to Bulin 47, Kevin Wai or 47 Music. The clip and its sound belong to their owners; see the takedown page for rights requests.
Will TikTok mute the sound?
It can, because the freestyle audio is recognised as music. Download the silent copy too and add the Bulin 47 sound from the app's library.
Can two people be in one video?
Not yet. The clip has one performer, so one photo replaces one person. The fan holding the speaker stays as he is.
The speaker is already playing
One photo, one tap, and you are outside that restaurant in Madrid.
