Problem with video only on Ipad

Hello - I have a problem with a video that plays well on my Macbook Air and on my iPhone. On the other hand, when I watch it on my iPad, the video is overexposed… How to solve this problem?
Thank you for your help

Hi @ALDEWAMB, welcome!

What do you mean with overexposed?

That page is password protected, but maybe a screenshot will be enough to start with.

Sorry - I removed the protection from the page… - With the Ipad, the image is white. With the Mac and the iPhone, the video is good
