i tried to do some keyframing on pictures like zoom in and zoom out. all the pictures which i used are over 1500x2000 pixels. it looked great inside fcp but when i exported them, it lost the quality and also there were jumps in the pictures as its zooming out

i don't know how to fix it, if someone can help me with it and also tell me how should i export it i mean what settings should i choose.

Thanks in advance.
