Step-by-step guide

How to make a Bulin 47 AI video from one photo

Add a photo, choose who it replaces (the freestyler, the speaker guy or both) and the length, and download a 720p MP4 of the original clip with your face. Three steps, about 3–6 minutes, from $9.90 per video.

Open the generator

At a glance

You need: 1 photo per person (JPG / PNG / WEBP, up to 10 MB)
Roles: The freestyler, the speaker guy, or both
You get: A 720p MP4, 6 or 12 seconds, 9:16 vertical
Time: About 3–6 minutes per video
Price: From $9.90 per video, paid once; no subscription

Step 1: Add your photo

Open the generator at the top of the home page and add one photo: JPG / PNG / WEBP, up to 10 MB, one person with the face clearly visible. You can set everything up before signing in; we ask you to sign in when you press generate.

Photos that work

One person per photo, no group shots
Face the camera; no sunglasses, masks or hands over the face
Even light and a sharp image, 720 px or more on the short side
Waist-up or full-body shots give the moves more room
Only yourself or adults who agreed: no celebrities, no footballers, no one under 18

Step 2: Choose the role, theme, size and length

Decide who your photo replaces and how long the video is. Every option costs the same, and the generator plays the original clip so you know what you’ll get.

The freestyler: You take the mic: the one improvising over the beat.
The speaker guy: You're the friend with the portable speaker, hyping every line.
Both: Two photos, two roles: you and a friend who agreed.
Length: 6 or 12 seconds, always 9:16 like the original post, for TikTok, Reels and Shorts.

Step 3: Generate and download

Press generate. If you don't have credits yet, the packs open right there, and after checkout you land back in the generator with your photo and settings kept. Rendering takes about 3–6 minutes; you can leave the page, and finished videos stay in your account for 30 days. Download the 720p MP4 when it's ready.

Post it on TikTok, Reels or Shorts

Open TikTok (or Instagram, or YouTube), tap +, and upload your MP4.
Your video comes with the clip’s original sound. If yours came out silent (a note under the result tells you), tap Add sound and pick the original Bulin 47 sound.
Write a caption and tag the friend who's in it.
Turn on the AI-generated content label (on TikTok it's under More options).
Post it. The same MP4 works as a Reel or a Short.

Fixes for common problems

The face doesn't look like me: Use a sharper, front-facing photo in even light, without sunglasses or a cap shading the face.
The render failed: Its credits come back automatically. Try again, ideally with a different photo.
I want the original audio: It’s already in your download: the MP4 comes with the clip’s original sound. Only if yours came out silent, add the trending sound inside TikTok or Instagram, as shown above.
My pet came out strange: The generator is tuned for people. Try a clear, front-facing photo of the pet, or use a person instead.

Questions before you start

What photo should I upload?

A photo of one person with the face clearly visible, as JPG / PNG / WEBP up to 10 MB. Front-facing, evenly lit photos with nothing covering the face give the closest likeness; waist-up or full-body shots give the moves more room. For two people, upload one photo each.

Who can I replace in the video?

Three options: the freestyler (the one improvising on the mic), the speaker guy (the friend holding the portable speaker and hyping), or both at once with two photos. Whoever you don't replace stays exactly as in the original clip.

Generator

Is it the original Bulin 47 video?

Yes. The generator starts from a short excerpt of the viral Bulin 47 video as Kevin Wai posted it on TikTok, with the “soy Bulin 47” line in it. Only the face of the person you pick changes; the moves, the camera, the crowd and the light stay exactly as they were. The clip’s rights belong to its owners: we credit and link the post, and for removal requests you can email support@aibulin47.video.

How long does it take?

Usually about 3–6 minutes per video; longer clips take a little more. You can leave the page and come back: finished videos stay in your account for 30 days.

Does my video have sound? Is it the original audio?

Yes. Your video comes with the original clip’s own sound: the voices, the beat and the crowd, in sync with the new face. The AI only makes the picture; when your video is ready, we add the clip’s real audio track to the MP4, untouched. If that step ever fails, you get a silent copy and a note saying so; on TikTok, add the original sound from Kevin Wai’s post when you post it.

Can I post my video on TikTok, Reels or Shorts?

Yes. Upload the MP4 and turn on the platform's AI-generated label (TikTok asks for it on realistic AI video). The original freestyle audio is already in the file; only if yours came out silent, add the trending sound in the app. The same file works on Instagram Reels and YouTube Shorts.
