How to make a Bulin 47 AI video from one photo

What does this Bulin 47 AI video generator make?

The studio is designed to create a 14-second, 9:16 vertical MP4 in 720p from one adult portrait. The person in your photo becomes the lead performer in a freestyle scene. A preselected reference video guides movement and framing, while the video model generates new frames. You do not need to write a prompt or edit a timeline.

The site is an independent tool. The video on the homepage is licensed reference footage, not a generated result. A real sample output should be published only after its input photo and output are cleared for public display.

The trend traces back to Kevin Wai’s creator post on TikTok. That post is useful for understanding the original performance; it does not itself establish permission to use the recording in a paid generator.

Choose a portrait the model can use

Start with one adult who agreed to appear in an AI-generated video. The upload accepts JPG, PNG or WebP files up to 10 MB. A recent photo with the face, hair and upper body visible gives the model more useful visual information than a distant group shot.

• Face the camera. Keep the eyes and facial outline visible. Heavy sunglasses, masks and hair across the face remove details the model needs.
• Use even light. Avoid a bright window behind a dark face, motion blur and extreme filters.
• Show some upper body. Clothing and shoulder position can help the generated performer feel connected to the portrait.
• Use one person. A group photo makes it unclear who should perform.
• Check permission. Use your own photo or a photo of an adult who has agreed to this use. Do not upload someone else's image without their consent.

From photo to finished video

1. Sign in and choose a pack. The account keeps your purchased video credits, jobs and private downloads together. Checkout opens only when the service is ready to deliver paid generations.
2. Add your portrait. Review the file preview in the studio and confirm the adult's permission. The selected scene is the first freestyle template.
3. Submit one video job. The service checks your balance and photo, reserves one credit, uploads the photo for Kie processing and submits an asynchronous task. The page then shows real queue, generation or saving states rather than a guessed percentage.
4. Return for the result. The browser checks your own task through this site's API. When Kie finishes, the MP4 is copied into private storage. You can preview it and download it from your account.

If Kie confirms a failed generation, the reserved credit is returned automatically. An uncertain submission or temporary provider error may need a support review before a credit is released; this avoids charging twice for a task that may still be running.

What stays familiar, and what may change?

The reference video gives the model a performance to follow, but the output is generated footage. Face shape, clothing, hands, lip movement, background details and timing may differ from the input or reference. This tool does not guarantee a frame-for-frame edit of an original clip. If an audio reference is configured, the model may use it during generation; that is not a promise of an untouched original soundtrack.

Watch the finished video before posting. Tell viewers it was made with AI where the platform or your audience expects disclosure. Do not use a result to imply that a real person performed, endorsed or said something they did not.

Quick answers

Do I need an app?

No. The studio works in a browser on a phone or computer. The result is a downloadable MP4.

Can I use a photo of a friend?

Only with that adult's permission to create an AI video with their likeness.

How long does generation take?

It depends on the provider queue and the media being generated. The studio displays the real task state and lets you return later. We do not promise a fixed completion time.
