Questions

API questions before your first call

At 720p, each second costs $0.25 and a minute comes to $14.82 (R$49.59, 828 credits). Each generation runs 3 to 16 seconds.
Create an account, make a key and send the request to the quote, which charges nothing. The smallest Q4 generation costs 42 credits, more than the 15 free ones: use those to try a cheaper model from the catalog.
With references: up to 15 images guide the character, product or style. From an image: the image you send becomes the first frame.
No. Buy a credit pack by card, or in reais with Pix from Brazil, and spend it on Q4 and every other model with the same key.
No. The Cut.Pro key calls Q4 without a Vidu account, with one balance for every model in the catalog.
Yes. With a CPF or CNPJ and full address in your billing details, the nota fiscal is issued after each payment is confirmed.
