i'm a newbie in ai video generation. i just wanted to make a construction animation with my own render. I have made several architectural renders, uploaded into google flow and with nano banana pro i've made construction phase images based on my render. but i can't generate a video which uses my render, tried a lot of different prompts, i used every veo model, it behaves like text to video feature. just doesnt refer to my image even in first-last frame option. after that i tried to make simple arc shot video, it failed again. what should i do?
