Questions

API questions before your first call

At 480p, each second costs $0.065 and a minute comes to $3.90 (R$13.05, 218 credits). Each generation runs 5 to 15 seconds.
Create an account, make a key and send the request to the quote, which charges nothing. The smallest Video 1 generation costs 19 credits, more than the 15 free ones: use those to try a cheaper model from the catalog.
With references: up to 9 images guide the character, product or style. From an image: the image you send becomes the first frame. Text only: the prompt describes everything.
No. Buy a credit pack by card, or in reais with Pix from Brazil, and spend it on Video 1 and every other model with the same key.
No. The Cut.Pro key calls Video 1 without a HeyGen 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.
