The dimensions of the generated video do not match the dimensions of the uploaded image.

Hello, I encountered an issue while using D-ID. I uploaded an image with dimensions of 690_1180, but when creating a calligraphy video task, the generated video dimensions changed to 491_839. Here is the link to my image: https://img.galaxyeye-tech.com/aigc-service/upload/202405/bb8b1878-67da-428b-a3d9-78da696c70e3.png. The task ID : tlk_talRMrTlDAhfquUro4GHt . Could you please help me resolve this issue?
