bulin47 FAQ — Guides and Answers
Everything about making your own one-photo identity-swap video — the essentials in one place.
Getting started
What is bulin47? bulin47 is a one-photo AI video generator. Upload a single photo and our model swaps you into a ready-made ~10-second template video — your face and overall look replace the protagonist, while the motion, body and original audio stay exactly the same.
How do I make a video for free? Sign in with Google and get 100 free credits — exactly enough for one full video, no credit card required. The free video has no watermark and includes the original soundtrack.
What photos work best? A clear, front-facing, waist-up portrait — one subject per photo, with the face visible and well lit. Avoid sunglasses, group shots and heavy filters.
Pricing and credits
How much does a video cost? One video costs 100 credits. Credits are charged only on success and returned on confirmed failure. See Pricing for subscriptions and credit packs.
What happens if my generation fails? Nothing is lost: credits are reserved on submit, charged only on success, and returned automatically in full on confirmed failure. Purchased credits never expire.
Output
Will my downloaded video have a watermark? No. Every downloaded MP4 — including free videos — has no visible watermark and includes the original soundtrack.
How long does generation take? Usually 3–10 minutes, plus queueing at busy times. Generation runs in the background — leave the page and download anytime from My videos.
Rules
Can I use celebrity or other people's photos? No. Any real person in your photo must be an adult whose image you have permission to use. Celebrity photos and nonconsensual impersonation are rejected by moderation. See the Content Rules.
