To reduce face distortion in a Bulin 47 AI video, start with a clear front-facing portrait, use even lighting, and avoid images with covered or unusually angled faces. These changes address the source of the problem before you spend more credits on another render.
Start with a better portrait
Choose one subject with a visible face and enough space around the head. The image should be sharp enough to distinguish the eyes, nose, mouth, and face outline. A casual phone photo can work, but a blurred screenshot or heavily filtered image is a weaker starting point.
Avoid:
- profile photos and extreme head turns;
- sunglasses, masks, or hands covering the face;
- dark lighting on one side of the face;
- face filters that change proportions;
- group photos where the subject is small;
- images with a large watermark across the face.
Check the framing
The subject should not be pressed against the edge of the image. A little space around the head and shoulders gives the transformation workflow more context. If the original photo is cropped too tightly, try the uncropped version or a portrait with a wider composition.
Test at the standard tier
The current 480p render costs 45 credits. It is a sensible testing tier because the main question is whether the selected photo remains stable during the prepared freestyle performance. If the face is distorted at 480p, moving to 720p or 1080p is unlikely to solve the underlying input problem.
Once the subject looks stable, you can choose 720p for 90 credits or 1080p for 180 credits when you need a larger export. Current rates and credit packs are listed on the pricing page.
Understand the template boundary
Bulin 47 AI uses a fixed workflow built around the prepared reference performance. It is not a free-form face-animation editor with a prompt box for manually directing every facial movement. The reference clip guides the movement, timing, camera structure, and audio synchronization.
This is useful when you want a recognizable version of the trend, but it also means that the source image and template compatibility matter more than adding extra text instructions. You cannot solve every visual issue by writing a longer prompt.
When the problem is technical
Separate a weak result from a failed render. If the video completes but the face is unstable, test a better photo. If the render stops, the output is missing, or credits were consumed without a finished video, use the Contact page to report the issue.
