Bulin 47 AI Result Looks Wrong? How to Fix Faces, Lips, Blur and Moves
Most bad Bulin 47 AI results come from the photo, not the model. A distorted face or odd eyes usually means a side angle, sunglasses or a small, low-light face; blur means a compressed or filtered selfie. Re-run with a sharp, front-facing photo that shows the head and upper body, and pick Seedance 2.5 (the full 19 s) for the steadiest faces and hands.
Symptom → cause → fix
| What you see | Usual cause | What to change |
|---|---|---|
| Face looks melted, stretched or like someone else | Side angle, face under ~200 px, heavy beauty filter | Front-facing photo, face filling about a third of the frame, no filter |
| Strange eyes, uneven or glassy | Sunglasses, glare on glasses, eyes half closed, dark photo | Eyes open and visible, no sunglasses, daylight or a bright room |
| Lips don't match the rap | The mouth follows the original performance; every model is approximate | Use Seedance 2.5; keep your mouth closed or relaxed in the photo, not a wide open laugh |
| Body moves don't match the original freestyle | Photo shows an unusual pose, a group, or props in front of the body | One person standing or sitting upright, arms visible, nothing held in front |
| Blurry or smeared video | Low-resolution, screenshot or WhatsApp-compressed selfie; 480p output | Use the original camera photo, not a screenshot; choose 720p |
| Blur only during the fast laugh and arm-up | The quickest frames are the hardest for any video model | Normal in small amounts; Seedance 2.5 reduces it |
| Original sunglasses or pink shirt stay on | Photo is a tight face crop, so clothes are guessed | Show hair, shirt and shoulders |
| Two faces blend or the wrong person is used | A group photo | Crop to one person before uploading |
| "Photo not accepted" and credits back | Seedance 2.5's review refused the photo (child, public figure, unclear subject) | Use a clear photo of an adult who agreed; or try the 15-second Mini clip |
The 30-second photo check
Before you spend credits, look at the photo and answer yes to all five:
- One person, and it's you or an adult who agreed.
- Facing the camera, both eyes visible, no sunglasses or mask.
- Bright, even light, no strong shadow across the face.
- Head and upper body in frame, not just a face crop and not a full-length shot from far away.
- The original photo, not a screenshot, a filter or a photo forwarded through a chat app.
A Samsung or iPhone front camera photo taken by a window passes all five. A night-club selfie with flash usually fails two.
Picking the model when a result went wrong
| Model | Length | Resolution | Credits |
|---|---|---|---|
| Seedance 2.0 Mini | 15 s | 480p | 10 credits |
| Seedance 2.0 Mini | 15 s | 720p | 20 credits |
| Seedance 2.5 | 19 s | 480p | 85 credits |
| Seedance 2.5 | 19 s | 720p | 190 credits |
- Mini, 15 s is the cheap test: if the face is wrong here, it's the photo.
- Seedance 2.5, 19 s is the full freestyle and the steadier model for faces, hands and the fast moves. It also checks the photo before rendering and refunds if it refuses.
Pets, cartoons and couples
- Pets: a clear, front-on photo of one animal works; the animal keeps its own face and fur and does the moves. Long-snout dogs side-on tend to warp.
- Cartoons: flat, clearly drawn characters work better than painterly or 3D renders with tiny faces.
- Couples or groups: the template has one lead role. Make one clip per person from cropped photos rather than uploading a group shot.
When it isn't the photo
If a video fails or is refused, the credits return automatically and you'll see the reason under the player. If a finished video is clearly broken (for example, a frozen frame or no sound), email support@bulinaivideo.org with the time you made it; we check it against the render log.
Questions and answers
Do I pay again to retry with a better photo?
Yes, a new photo is a new video, so it costs credits again. Failed or refused videos are refunded automatically, but a finished video that you don't like isn't. That's why the photo checklist below is worth the minute it takes.
Why does my video still show Bulin 47’s sunglasses or pink shirt?
The model fills in anything your photo doesn't show. A tight face crop leaves it guessing about clothes, so it can keep the original sunglasses or mesh shirt. Use a photo that shows your hair, shirt and shoulders.
Can I fix the lip sync after the video is made?
Not on this site. The mouth follows the original rap timing, which is close but not exact on any current model. If it bothers you, posting with the sound at a lower volume, or using the trending sound in TikTok, hides small offsets.
Is Mini or Seedance 2.5 better for faces?
Seedance 2.5 holds the face and hands steadier through the fast laugh and arm-up moment and reviews the photo first. Mini is fine for checking whether a photo works before paying for the full 19 seconds.
