Document type: public usage summary, not a verbatim page export.
Last substantive review: 2026-10-11 (Asia/Shanghai).
Purpose: Compare credit costs and packs, free preview and sign-in requirements.

Generation uses account credits. Pack video counts refer to standard 480p exports; a pack is not an entitlement to the same number of HD videos.

## Generation costs

480p costs 10 credits per new video; 720p costs 22. Original and Custom cost the same. Credits are reserved on submission, consumed on successful completion and released if the task fails or is blocked. Viewing or downloading an existing result uses no additional generation credits.

## One-time packs (USD)
| Pack | Price (USD) | Credits | Standard 480p capacity | HD 720p capacity |
| --- | --- | --- | --- | --- |
| Single | $9.99 | 10 | 1 video | Not enough for one HD video |
| Friends | $24.99 | 30 | 3 videos | 1 video + 8 credits left |
| Creator | $69.99 | 100 | 10 videos | 4 videos + 12 credits left |

Pack video counts refer to standard 480p generations, not HD entitlements. Credits can be mixed between qualities. These are one-time PayPal purchases with no subscription or automatic renewal. Purchased credits have no scheduled expiry under the current policy. Check [the pricing page](https://bulin47-ai.com/pricing) and checkout for current prices, availability and applicable payment details before purchasing. A displayed pack is not purchasable if checkout is unavailable. Review the total, disclosed taxes and any payment-provider conversion charges before paying. Credits are non-transferable; no scheduled expiry does not guarantee that generation costs or features never change.

## Accounts and free preview
Generation, purchases and access to your saved task history require sign-in. Google and email-link sign-in are the available interface options. For email sign-in, enter your address, choose Continue with Email, then open the email and click its one-time link within 5 minutes. No code is entered in the login dialog. A failed send should leave the dialog open with an error; a successful request shows Check your email. Delivery and Google sign-in depend on service availability. Watching public examples and selecting a photo for local preview are free; preview is not video generation. The current new-user gift is 2 credits, valid for 30 days; it does not cover one 10-credit generation.

Do not confuse failed-render credit returns with a PayPal cash refund. Completed aesthetic imperfections do not automatically qualify for either; a new attempt consumes credits.
