Use este endpoint quando uma imagem de origem não for suficiente e você quiser que o Kling crie movimento a partir de várias imagens de referência.

​
Antes de chamá-lo

  • Prepare de 2 a 4 imagens em image_list
  • Comece com model_name: kling-v1-6 ou outro modelo atual que você tenha validado
  • Mantenha o primeiro teste simples: um prompt curto, sem máscaras de movimento, sem configurações extras de callback

​

Submit the multi-image request

Persist the result
