Bulin 47 AI Video Generator is an AI tool that generates templated short videos based on a single portrait photo, and belongs to the AI image/video generation category.
Purpose It is used to convert a photo of a person into a vertical 720p video of about 23 seconds. During generation, the person in the user's photo replaces the protagonist in the template, and the template determines the performance movements, visual composition, and background music. It is officially described as "making a Bulin 47 AI video from one portrait," with the core being a fixed template + user photo compositing method.
Main capabilities
- Single-photo driven: uses a photo of one person or an upright humanoid character, requiring the face, shoulders, and torso to be clearly visible.
- Fixed performance template: the template comes with fixed performance, composition, and soundtrack, and the user's photo replaces the protagonist.
- Output specifications: vertical 720p, duration about 23 seconds.
- Other templates: the official page also mentions a 17-second Cheba Man dance template, which likewise uses the template's built-in performance and soundtrack.
- Draft feature: drafts only save notes and cropping settings locally on the device, not the photo; notes are visible only to oneself and do not change the video content.
How to use
- Choose a photo: upload a photo of yourself or an authorized adult, or a photo of an upright humanoid character, ensuring the face, shoulders, and torso are clear and well lit. The official statement clearly says ordinary photos of four-legged animals such as cats and dogs are not suitable and may produce poor motion results.
- Preview and crop: previewing and cropping are completed locally in the browser and are free.
- Generate: after logging in, confirm the price and click Generate. After generation is confirmed, the cropped photo will be uploaded to private storage and temporarily authorized for processing by the AI service.
- View results: check progress in My videos, and once the video is complete you can watch and download it. You can close the page midway through generation and return with the same account to continue checking.
Price and credits
- Each complete video consumes 100 credits.
- One-time credit packs start at US$9.90 (100 credits), valid for 12 months.
- The price is shown before generation, and the page states there is no subscription model.
- If generation ends but no deliverable video is produced, the reserved credits will be returned according to the credit refund policy; the refund status can be viewed in My videos and the credit record, and returned credits are different from a refund to the payment card.
- Public examples can be viewed for free, and photo preview and cropping are free.
Applicable scenarios and limitations The applicable scenario is users who want to quickly create a vertical short video with fixed performance and soundtrack from one portrait, such as for personal entertainment, socialsharing, and so on. Limitations and notes:
- The photo must be of one authorized adult or an upright humanoid character, and must ensure the face, shoulders, and torso are clear; photos of four-legged animals are not suitable.
- AI may change facial details, hands, movements, and background, and some transitions may be obvious; the official statement does not promise perfect lip sync or seamless motion.
- Friends and background will in principle be retained, but the degree of retention and identity consistency are not guaranteed.
- Currently there is only the first template with fixed performance and output format, and custom videos, multiple subjects, or other output formats are not supported.
- The official estimated generation time is about 8–11 minutes under normal conditions and may be longer when busy, and this does not constitute a delivery guarantee.
- This project is an independent creative project and is not affiliated with or endorsed by Bulin 47 or any artist.
- Downloading a video does not mean obtaining rights to third-party music, performances, or images, and before commercial use you must ensure you have the necessary authorization.
Data and privacy The photo remains on the user's device before generation, and after generation is confirmed it is uploaded to private storage and temporarily accessed and processed by the AI service; draft notes and cropping settings are stored only on the local device and do not include the photo.
The above is the information explicitly provided in the official text; other features, charging details, or platform details are not yet provided.
