> How to make the Bulin 47 AI video with yourself or your pet in the street freestyle, where the trend came from, what happens in each second, and what our test renders taught us.

The Bulin 47 AI video is the clip of someone in black wraparound sunglasses rapping straight at a phone outside a red-lit restaurant, a crowd packed around them, an arm thrown in the air and a grinning shoulder bounce on the beat. The real moment happened on 2 October 2026, and within days people were making AI versions of it with themselves, footballers and their dogs. Below is where the trend came from, what each second of it does, and how to make your own.

## Where the Bulin 47 AI video trend came from

Kevin Wai, a Colombian street rapper who posts as @kevincitooficial11 on TikTok, walks up to people with a portable speaker and freestyles at them. Outside a restaurant in Spain, under red lights, he started a verse at Bulin 47, the Dominican dembow artist, who was wearing black wraparound sunglasses. Bulin 47 answered on the spot: "no ando en película, no ando en paquete, ya todos me conocen, soy Bulin 47", then dropped into a loose shoulder dance while Kevin took his turn.

Kevin's clip is 46 seconds long. Dominican and Spanish outlets reported more than 50 million views across platforms by 7 October and more than 70 million a day later. The AI versions arrived on 7 October: the most shared early one, 19 seconds long, swaps Bulin 47 for a footballer and passed 3 million views. Since then the Bulin 47 AI video has been made with players, politicians, cartoon characters and plenty of pets. Bulin 47 released a single, "Dame Hombro", around the same time. This site isn't affiliated with Bulin 47, Kevin Wai or anyone involved in the clip.

## What happens in a Bulin 47 AI video, second by second

Most versions keep the same fifteen seconds of the original, starting just before the famous line. We went through it frame by frame:

1. **0–5 s: the verse.** Facing the phone, rapping fast, one hand keeping the rhythm, mouth wide on the loud words. "Soy Bulin 47" lands right at the end.
2. **5–7 s: the glance down.** The line is done; a passer-by's white sleeve sweeps past the lens.
3. **7–9 s: arm in the air.** A hand to the top of the head, then the whole arm up, hyped.
4. **9–12 s: the shoulder bounce.** Head down, a big grin, shoulders bouncing on the beat while the friend in front raps.
5. **12–15 s: back to the crew.** Looking up, still grinning, talking to the friend holding the phone and speaker.

The audio does as much work as the moves. The verse, the beat from the little speaker and the crowd noise are what make people recognise the trend before they read the caption.

## 3 ways to make your own Bulin 47 AI video

**1. Edit the original clip.** Some video editors take the original footage as a reference and paint your face or your pet over the rapper. It looks closest to the clip, but the original people, including Kevin, stay in your video, and you are working with someone else's footage.

**2. A regenerated scene.** Other tools generate a new street from a text prompt and your photo. They are quick, but the moves rarely match, the crowd changes every time and the audio is often new music instead of the freestyle.

**3. One photo on our page.** On [Bulin 47 AI](https://airapduo.io/bulin-47-ai.md) you add one photo of yourself or your pet. We copy the moves and the camera from the clip second by second, build the street fresh around you, warm it up to the original's red and add the freestyle audio.

## How we copy the moves without copying the footage

Our version never uses a frame of the original. We turned the fifteen seconds into a depth map: a moving picture of how far each part of the scene is from the camera, with shapes and motion but no faces, colours or clothes. The video model reads it as choreography and camera movement and paints a new street on top, with you where the rapper stood.

(Image: Two pairs of frames: a coloured depth-map silhouette of a crowd with one figure raising an arm, next to a man in a red cap and sunglasses doing the same outside a red-lit restaurant — The depth map (left of each pair) only carries the moves; the street, the crowd and the person are new.)

For pets we blur the rapper's outline in the depth map, so a dog or cat is not forced to copy a human arm. It sits on a stool among the crowd, raps with its own mouth, throws its head back and bounces to the beat.

## What our Bulin 47 AI video tests got wrong

We made our test renders at 480p before any example, and compared each one with the original frames side by side.

- **The sunglasses kept ending up on the head.** The model pushed them up to show the eyes until we asked for them over the eyes, lenses covering them.
- **Full-length photos pulled the camera back.** A head-to-toe photo made the model film a wide shot so the shoes fit in. Every Bulin 47 AI video is now filmed from the waist up, whatever photo you add.
- **A hand appeared out of nowhere.** The rapper's hand sometimes popped out from behind the friend's head with no arm attached. We now keep both hands on the rapper's own arms.
- **The phone went dark.** Removing a stray selfie from the phone screen turned it off; the original's screen glows, so ours does again.
- **A standing dog grew human hands.** A pet copying the arm moves did not work, so pets sit and move their head instead.

Our test renders took between 2 min 44 s and 3 min 19 s, plus about half a minute for the colour and the audio.

## Tips for the photo you upload

- **One person or one pet, face clearly visible.** A front-facing photo in good light keeps the likeness best. Nobody else in the shot.
- **Any framing works.** Full-length, seated or a selfie: the video is always framed from the waist up, like the original.
- **Glasses are fine.** Everyone gets the trend's black wraparound sunglasses anyway; your own glasses are replaced.
- **Adults only.** Photos of children are turned away. Use only photos of people who said yes.
