Street freestyle video from one photo
From an uploaded photo of the user or of a friend who has agreed, the AI freestyle video tool makes a ten-second vertical clip of that person rapping on the spot: a sunny sidewalk outside a busy terrace, a friend holding up a small speaker with an upbeat dembow beat, and people turning to watch, film and cheer. The format is the street freestyle behind the Bulin 47 trend, made new around the photo, with the beat and the rap vocals in the clip.
One photo, one freestyle
The tool first looks at the person in the photo, including face, hair, build and clothes, then makes a single continuous handheld shot of that same person freestyling to the beat, with shoulder bounces, head nods and hand gestures, while the camera pushes in slowly. The face stays the one from the photo throughout, and the clip has no captions, logos or watermark.
Ten seconds, vertical, with sound
Every clip is ten seconds in 9:16 with the beat and the rap vocals generated together, at 480p, 720p, 1080p or 4K, with 720p selected first. The rap is in Spanish, in keeping with the trend, unless another language is requested in the twist, such as “rap in English about my dog”.
A new clip, not the original
The tool does not use the viral video, its song or anyone else's likeness. It makes a new clip of the person in the uploaded photo. Arumi is not affiliated with Bulin 47 or the creators of the original video. Only a photo of the user, or of someone who has agreed to be in the clip, should be used.
Uses
Trend clips for social feeds
A ready-to-post 9:16 clip for TikTok, Instagram Reels or YouTube Shorts, with the sound already included.
Friends and group chats
A friend who has agreed can be placed in the freestyle, and the clip shared with the group.
Custom variations
The scene, the outfit or the subject of the rap can be changed in a few words, or the classic street freestyle can be left as it is.

How credits work for freestyle videos
One price per run, shown before the run starts.
The clip is ten seconds long with sound, at 480p, 720p, 1080p or 4K. Before you click, the Generate button shows how many credits this run costs. Automatic settings are priced at the most expensive possible tier. A successful generation is charged exactly the quoted credits. Failures caused by us or blocked by our content checks cost nothing. If the generation service does not charge for a failure, neither do we. If it does, you pay for the actual usage, capped at the quote, and the record shows the charge.
If the video cannot be made, the page explains why and whether a charge was made. Our own failures and photos stopped by the content check cost nothing.
The freestyle video is one of the AI tools that are available with any credit pack and remain available while the paid credits are valid.

What is the Bulin 47 freestyle trend?
A viral clip of a street freestyle, in which an artist outside a restaurant raps on the spot to a beat from a stranger's speaker. People now recreate it with themselves or their friends as the rapper. This tool makes a new clip in that style from the uploaded photo and does not use the original video or song.
Which photos work best?
One person, a sharp and well-lit face looking roughly at the camera, and ideally the upper body in frame. Sunglasses, heavy filters, group shots and strong shadows across the face should be avoided.
Can I choose the language or what the rap is about?
Yes. It is entered in the twist box, for example “rap in English about Monday mornings” or “on a rooftop at sunset in a red hoodie”. If the box is left empty, the result is the classic street freestyle in Spanish.
Can I use a photo of someone else?
Only of someone who has agreed to be in the clip. Photos of celebrities or of people who have not agreed must not be used.
How long is the video and in what format?
Ten seconds, vertical 9:16, MP4 with sound, ready for TikTok, Reels and Shorts.
