I just want a book to open in Image to Video

I created the image of a book with a viking face on it (first image). I prompted inside the image to video generator "The cover opens to a page in the middle of the book. The page is very ancient and appears weathered and discolored, the page inside the book that we wee is filled with text in the style of viking runes."
I am using the image as the first frame of the video generation.  

 I have tried no less than 8 times and burned through 800 credits in this experiment and no matter how I prompt the book to simply open it always opens like a trifold birthday card.

The only good thing is taht it ultimatly ends up looking like I want.

Yes, I did try to use the end frame as the last frame of the video but it still opens the book as though it is a trifolded birthday card and not a book with just two covers.

Honestly, it seems like opening a book should be a simple enough promt. 
What can I possibly be missing?  
any help would be appreciated before I am completly out of credits....Again....
Thanks for any guidence on what the prompt should actually be to open a book to the middle pages.
