What is the Bulin 47 AI Video Generator?

It puts your face on the lead performer of the Bulin 47 freestyle while keeping the scene's moves, lighting, crowd, camera and original sound, so it looks like you were rapping there.

Do I need to upload the original video or write lyrics?

No. The clip is already set up and follows the original performance, so you only upload one photo. For your own lyrics, use another template such as Pet Rap or Roast Rap.

Does the video have sound, and what format is it?

Yes. By default you get a ready-to-post vertical 9:16 MP4 with the original Bulin 47 freestyle audio, and the mouth follows the original timing so it matches. Pick Silent if you want to add your own sound later.

How long does it take and what does it cost?

15 seconds costs 1,500 credits at 720p or 2,250 at 1080p; 30 seconds costs 3,000 or 4,500. It takes about 3 to 9 minutes and uses purchased credits. If generation fails, the credits go back automatically.

Edit @video_1. Replace only the lead freestyle rapper (the bald man in dark sunglasses and a light pink mesh short-sleeve shirt, tattooed arms, gold watch and chain, rapping at the camera) with the person in @image_1.

Identity: keep @image_1's face, skin tone, hairstyle, facial hair and age exactly, stable in every frame, including head turns, fast moves, profile angles and motion blur. Keep the rapper's original outfit from @video_1; change only the head, face, hair and visible skin.

Keep everything else unchanged from @video_1: the red-lit lobby with red stairs, the fan in the maroon hoodie in front holding up a phone and a black portable speaker, the crowd and security behind, and their reactions, the camera movement, framing and cuts, the lead's body movement, hand gestures and timing, every other person, and the lighting. Realistic hands with five fingers, natural anatomy, consistent body proportions.

Lip sync: copy the lead's mouth shapes, jaw movement and expressions from @video_1 frame for frame, with the same timing, so they match the original vocal track.

No subtitles, no captions, no text, logos or watermarks, no extra people, no merged faces.

Kling 4.0 edits the 15-second Bulin 47 clip at 720p: the lead rapper becomes the person in your photo, while the red-lit lobby, speaker, crowd, camera and timing stay. Then the original freestyle track goes back on, so the lips match. Paid from purchased credit; a failed video returns its credits.

What makes a good one

Use a sharp, well-lit, front-facing portrait of one person, waist-up, with eyes, nose, mouth and jawline clearly visible.
Skip sunglasses, masks, hats over the eyes and heavy filters; they make the face drift on fast head turns.
Pick 15 seconds for a quick social post, 30 for the full freestyle, and 1080p when you want the sharpest face.
