The Bulin 47 trend is the clip everyone is remaking in October 2026: a red-lit club entrance at night, a fan holding a speaker, and a rapper in black sunglasses answering him with a verse made up on the spot. In the original, the rapper is Bulin 47. In the versions flooding TikTok, Reels and Shorts, he is anyone: Messi, Cristiano Ronaldo, Mbappé, Haaland, cartoon heroes, somebody's uncle. This guide covers where the clip comes from, why it remixes so well, and how to make your own version in eroq with a character you made, using the ready-made Street freestyle template.

## The original: Bulin 47 and Kevin Wai

Bulin 47 is a Dominican dembow artist. As he was about to walk into a restaurant, a fan, Kevin Wai, stopped him with a speaker playing a dembow beat and started to improvise. Bulin 47 answered with his own rhymes, filmed on a phone in the crowd, and one line stuck: "No ando en película ni ando en paquete, ya todos me conocen, soy Bulin 47". The video passed 50 million views across social networks, and the moment became a real song: Bulin 47 and Kevin Wai released "Dame Hombro" with an official video.

The AI versions came right after. They keep the moves and the audio of the original recording and put another face on the rapper, footballers first, then politicians, singers and anyone a feed could think of.

## Why this clip works so well as a trend

- **A real moment.** A phone in the crowd, a fan, a verse nobody planned: it reads as true, whoever raps it.
- **One face to swap.** The rapper faces the camera the whole time, and the fan stays in the foreground. Change the rapper and the scene still makes sense.
- **The line.** "Soy Bulin 47" is the punchline. Hearing it come out of someone else's mouth is the whole joke.
- **Short enough to loop.** The verse fits in fourteen seconds, from the first bars to "Bulin 47".

## How the trend versions are made

Most versions you see map a photo onto the rapper with a face filter. eroq keeps the real performance, every move, gesture and word, and replaces the rapper in it. That is what [Replace](/studio/video?mode=replace) is for: change one thing in a clip and keep the rest of the shot.

## Make it in eroq with the Street freestyle template

1. **Open the template.** In the studio, go to Video, then the Replace tab, and click **Street freestyle**, the first card with the Top trend badge under Trending templates, or [open it directly](/studio/video?mode=replace&template=street-freestyle). It also leads the Trending now row on your [studio home](/studio). The 14-second vertical clip loads from eroq, already cut to the verse: nothing to download. Replace takes all fourteen seconds; Replace Pro takes ten at most, so trim the range to the ten you want.
2. **Cast your rapper.** The composer shows one slot, Rapper. Pick a character and the instruction writes itself: your character replaces the rapper in black sunglasses and the pink mesh shirt, while the fan with the speaker, the crowd and the red light stay. No character yet? [Create one](/studio/characters/new) from a few photos and a description; it opens in a new tab, so the template stays loaded.
3. **Choose the engine.** Replace reads your character's description and costs 8 credits per second of clip. Replace Pro paints your character from their look sheet into the first frame, so the face really matches, and costs 59 credits per second, from the Creator plan.
4. **Click Replace.** The edit takes a few minutes and lands in Creations. The moves, the gestures and the lip-sync come from the original performance.
5. **Keep the verse.** Replace Pro returns the edit with the original audio under it, ready to post. Replace returns a silent clip: under the result, **With original sound** downloads it with the original audio.

## Getting a good result

- **Give your character a look sheet** if you use Replace Pro. It only paints characters that have one; without a sheet, the edit falls back to their written description and the face can drift. [Consistent characters in AI video](/blog/consistent-characters-ai-video) explains how sheets hold a face.
- **Say what they wear.** Your character keeps their own face, hair and outfit by default. For the black sunglasses or the pink mesh shirt, add it to the instruction: the text stays editable after the template writes it.
- **Keep the motion sentence.** The instruction asks for the same verse with the exact same moves, gestures and lip-sync. If you edit the text, keep that part: it is what holds the performance.
- **Shorter is cheaper.** The trim bar under the clip keeps only part of the fourteen seconds, and the price on the button follows the length.

## What it costs

| Engine | The whole clip | Notes |
|---|---|---|
| Replace | 112 credits | Reads your character's description |
| Replace Pro | 590 credits for ten seconds | Takes ten seconds at most, so trim the clip first. Plus 10 credits for the painted first frame, Creator plan |

Trimmed to 8 seconds, the same edit costs 64 credits on Replace. Credits come with every [plan](/pricing), and an edit that fails is refunded.

## Who can take the mic

The most shared versions star famous faces. On eroq you cast characters you made: an original character, yourself, or a friend who agreed to it. The [usage policy](/legal/aup) asks for characters who are 18 or older and rules out real, identifiable people without their consent. The clip and the verse belong to Bulin 47 and Kevin Wai, so post your version the way the trend does: as a fan remix that credits the original.
