Bulin 47 AI

Bulin 47 AI generates a ~23-second vertical freestyle video from a single input photo, using the original freestyle sound. Your uploaded portrait becomes the lead character—covering visible face, hair, and outfit—while a prepared reference freestyle guides movement and camera timing.

The generator focuses on “one photo → one full freestyle.” You can watch the result with sound and download an MP4 in a vertical format designed to play with the original audio.

You’ll also choose who appears in the scene. Keep the Original crowd (the street crowd) or switch to Custom to replace up to 4 additional people alongside the lead. In Custom mode, you assign photos to crowd roles and review what appears as people move across the frame, since details can shift between frames.

Quality is selected before generation: Standard is 480p and uses 10 credits, while HD is 720p and uses 22 credits. There’s no subscription. One-time credit packs start at USD 9.99 (with options for 1, 3, or 10 HD videos). If a render fails or is blocked, reserved credits are returned to your available balance—completed videos with imperfect details are not treated as failed renders—and purchased credits do not expire.

What does Bulin 47 AI create from my photo?

It turns one consenting adult portrait into an approximately 23-second vertical MP4 freestyle video, using the original freestyle sound. Your photo defines the lead’s visible appearance while the reference clip guides movement.

Do I need to write a prompt to generate a video?

No—there’s no prompt step. You upload your photo, choose the crowd mode and quality, then generate and download the MP4.

What are the crowd options: Original vs Custom?

Original keeps the street crowd. Custom replaces up to 4 additional people using role-based crowd replacements (your video still has one lead). You can preview and review what appears as people move.

What photo requirements should I follow?

Upload one person per photo with face, hair, and upper body visible. Use a clear, evenly lit image (avoid sunglasses, heavy filters, and covered faces) and include the clothing you want referenced. Supported formats are JPG, PNG, WebP, or HEIC/HEIF (up to 10 MB per image).

What quality options are available, and how many credits do they use?

Standard is 480p and uses 10 credits per 23-second video. HD is 720p and uses 22 credits per 23-second video.

What happens if generation fails or the result looks wrong?

If a render fails or is blocked, the reserved credits are automatically returned to your available balance (your payment isn’t refunded). A completed video with imperfect details isn’t considered a failed render, and each new generation uses credits.
