Photo tips for your Bulin AI video
Simple portrait choices that help Bulin AI follow your face and the reference motion.
Show one face clearly
Choose one adult, looking toward the camera with the face visible. Avoid sunglasses, hands covering the face, extreme side profiles and photos with several people. This preset supports one person only.
Keep useful detail
A clear original photo is better than a small screenshot or heavily filtered image. Use even light and avoid deep shadows across the face. A head-and-shoulders portrait is a sensible starting point. Do not expect clothing or the background to stay exactly the same: the motion reference also influences the generated scene.
Upload a supported file
The studio accepts JPG, PNG and WebP up to 10 MB. If a phone photo uses another format, export a supported copy before selecting it. Selected photos stay on your device until the generation upload begins. Uploaded media is associated with your signed-in account.
Judge the preview
Your free 4-second preview can help you evaluate whether the portrait works with this motion. It is still an AI result. A full video is a separate render, not an extension of the preview; details may change. A successful result that you want to regenerate requires another credit allowance.
Only upload your own photo or an adult portrait you have permission to use. Start with the preview.
