A warped Bulin 47 AI video usually starts with a difficult source photo: the face may be too small, the angle may be too extreme, or the image may contain shadows and obstructions. A higher output resolution can change export size, but it cannot fully compensate for unclear input material.
The most common causes
The face is not clearly visible
The workflow needs a recognizable subject. Sunglasses, hands over the face, heavy shadows, and hair covering key features can make the replacement less stable. Choose a photo with an unobstructed face and even lighting.
The image is a profile or extreme angle
A side-facing portrait gives the system less information about the front of the face. A front-facing or slightly turned image is generally easier to transform into the prepared performance.
The subject is too small in the frame
A distant full-body photo or group shot may leave too few useful facial details. Select a single-subject portrait where the head and upper body are clearly visible.
The original image is already distorted
Wide-angle selfies, aggressive beauty filters, stretched images, and screenshots of low-quality videos may contain unusual proportions before the AI process begins. Use an original, naturally framed photo whenever possible.
The background competes with the subject
Busy backgrounds, bright objects behind the head, and similar colors between the face and the background can make the subject boundary harder to maintain. A simple background is often easier to work with.
A practical repair workflow
- Stop using the current photo for another expensive render.
- Choose a clearer, front-facing image with a visible face.
- Remove sunglasses, stickers, or other elements covering the face.
- Try the 480p option first so you can test the new input at the lowest current render cost.
- Review the result before moving to 720p or 1080p.
The Bulin 47 AI studio uses a prepared performance template. That means the source photo is especially important: you are selecting the subject that will be placed into an existing motion and camera structure rather than describing every scene detail with a custom prompt.
What resolution can and cannot fix
Resolution affects the size and detail of the exported video. The current rates are 45 credits for 480p, 90 credits for 720p, and 180 credits for 1080p. Moving to a larger output can be useful after the subject replacement is already stable, but it does not repair an obstructed face or an unsuitable angle.
When to contact support
If the task never completes, the video is missing, or credits were charged for a failed render, contact support with your account email and a short description. Include the approximate generation time if possible. For a completed but visually weak result, first test a better source photo before reporting a technical failure.
