API questions before your first call
- At 480p, each second costs $0.052 and a minute comes to $3.12 (R$10.44, 175 credits). Each generation runs 5 to 20 seconds.
- Create an account, make a key and send the request to the quote, which charges nothing. The 15 free credits cover 5 seconds at 480p with LTX 2.3.
- Text only: the prompt describes everything. First and last frame: two images become the start and the end of the video. 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 LTX 2.3 and every other model with the same key.
- No. The Cut.Pro key calls LTX 2.3 without a Lightricks 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.
