Usa este endpoint cuando una sola imagen de origen no sea suficiente y quieras que Kling construya movimiento a partir de múltiples imágenes de referencia.

​

  • Empieza con model_name: kling-v1-6 u otro modelo actual que hayas validado
  • Mantén simple la primera prueba: un prompt corto, sin máscaras de movimiento ni configuraciones adicionales de callback

​
