If I look at this page on my website in Chrome or Firefox it works but if I use Safari 18.3 on a Mac running Sequoia 15.3.1 the video does not show all I can see is a white gap.

However I have another page called Videos
And on this page all the videos are properly embedded.
I am not a coder hence my use of Rapid Weaver but I am confused as to why videos display correctly on other browsers but not safari but some pages do work on Safari.
