How to make it
How to make a Bulin 47 AI video
The whole flow takes a few minutes: one photo, one credit, one video. Here is exactly what to do — and what makes generations fail.
02
Sign in and buy a credit
Sign in with Google or email, then buy one video credit for $9.99 or a 3-video pack for $24.99. Credits never expire.
03
Generate
Submit from the workspace. Wan 2.2 Animate Replace swaps you into the Bulin 47 freestyle reference, and we merge the original audio track back.
04
Download in time
Your video appears in the workspace and My Creations. The private download link expires six days after delivery — download the MP4 before then.
Why generations fail
Face not found or too small
The model needs one clear face. Cropped, tiny, blurry, or side-profile faces are the most common failure. Choose a sharper front-facing photo.
More than one person
Group photos confuse the swap. Crop to a single person before uploading.
Photo rejected by safety review
Every photo passes an automated content-safety check. Rejected photos are never generated, and no credit is consumed.
Result did not pass review
Finished videos are checked before delivery. If the output fails the check, the credit is refunded and no video is delivered.
Downloaded on iPhone? Here is where your video went
Safari does not save downloads to your camera roll — it puts them in the Files app. Open Files, go to Downloads, and tap your MP4. Then tap the share button and choose Save Video to move it into Photos, where you can post it like any other clip.
