What can you do without paying?
You can preview the Bulin 47 effect before buying credits, then read the tutorial and compare source lengths. The separate blue-character case is also free to watch. These actions help you understand the lead role and frame before spending generation credits.
Uploading a file is preparation, not a free generated-video trial. The silent six-second character case is an existing public example, not a personalized preview of your own portrait. A new MP4 requires a reviewed generation request.
How many credits does one Bulin 47 video use?
The current published rates are 80 credits per started source second at 480p and 180 at 720p. The selected source length and resolution determine the generation quote. Cropping to square or vertical does not change that amount.
These examples use the prepared 5, 12 and 23-second cuts. Check the live studio before confirming in case pricing changes. An advertised package price is not necessarily the price of the particular clip you have selected.
| Source length | 480p | 720p |
|---|---|---|
| 5 seconds | 400 credits | 900 credits |
| 12 seconds | 960 credits | 2,160 credits |
| 23 seconds | 1,840 credits | 4,140 credits |
Required credits and purchased credits are different
The generation quote is the total used by the request. If you already have an available balance, you only need to purchase the missing amount. The studio can offer a one-time exact-credit purchase, alongside eligible credit packs and the monthly plan.
For example, a 400-credit generation with 200 available credits needs 200 more. Exact-credit purchases have a minimum purchase amount, so a very small shortfall can require buying more credits than the shortfall alone. Read the purchase amount before opening checkout.
When does a paid generation begin?
The final generation confirmation submits the request and reserves its quoted credits. Buying credits, returning from checkout or refreshing a result page does not automatically create another video. Your settings should be reviewed again after your balance updates.
If a request is confirmed failed, its result page reports the credit accounting status. A completed video that needs a different portrait is a new generation, with another quote; a subjective likeness concern is not the same as a failed processing request.
How to make a lower-cost first request
If a short opening is enough, compare the 5-second 480p choice with the longer and higher-resolution options. Before submitting, check that the portrait is clear and that the selected crop includes the lead's face and gestures.
Use the full cut when the longer performance matters, rather than paying for length you do not need. A shorter request is still paid and does not guarantee a better identity match. Review the actual completed MP4 before sharing.
