Where the Bulin 47 freestyle comes from
Updated : 15 seconds only now, at the same price, with a free 2-second preview first (one per account).
Bulin 47 is a Dominican urban artist and comedian. Latination reports that a spontaneous dembow freestyle he did with Kevin Wai in Spain, with Kevin holding a portable speaker playing the beat, passed 50 million views, and that AI remakes of the clip with other people in it followed on TikTok and Instagram. We have not checked the view count ourselves. The original clip is on Kevin Wai’s TikTok.
This effect works from that clip. You perform the part of the man in the pink shirt who faces the camera, for 15 seconds from the start of the freestyle; Kevin Wai with the speaker, the crowd and the camera follow the original frame by frame. For the first seven seconds your mouth follows his lines; after that, when the other voice takes over, you keep his moves, turning, leaning in and laughing, without rapping.
The download keeps the original sound. Lip sync is close but not frame-exact, and small details like a tattoo can carry over from the original. RapVideo is not connected to Bulin 47 or Kevin Wai.
Why one photo?
Only one person faces the camera in the clip. The one holding the speaker has his back to it the whole time, so a second photo would never show a face; he stays as he is in the original.

Tips for a better freestyle
- Face the camera, eyes visible: sunglasses and heavy filters hide what the video follows.
- Show your hair, clothes and upper body, not just a tight face crop.
- One person per photo, sharp and well lit.
- Use your own photo, or a friend’s with a yes. Famous faces are not what this is for.

Does it keep the original sound?
Yes. The original freestyle goes in with the clip and the video keeps it, so it plays as the clip did.
Can I make it with a friend?
The clip has one person facing the camera: the one holding the speaker never faces the camera. For two people, try an AI rap duo video or the Hotel Lobby AI booth.
Can I put a celebrity in it?
No. Use your own photo or one of someone who said yes. RapVideo is not affiliated with Bulin 47 or Kevin Wai.

15 seconds: 7 credits at 480p, 12 at 720p, 24 at 1080p, rendered on Wan 3.0. Longer or sharper clips cost more, and the price shows before you render. The only free part of RapVideo is one 2-second watermarked preview per Google account, of the default Hotel Lobby video or the Bulin 47 Freestyle; everything else is paid with credits. Packs start at 10 credits for $9.99, and a failed render gives its credits back.
