Video quality has changed and text is now hard to read in places

Can anyone suggest how to reinstate the legibility of the white text over the looping video on my website please? When the videos were originally uploaded the contrast was fine. Overnight the videos appear bleached out in places making the white text illegible.

I’m aware that there were block padding issues with SquareSpace last night. The deterioration in the quality of my website’s videos coincided with the block padding issues. Could they be connected and is anyone at SquareSpace looking into video quality issues? 

All helpful suggestions or updates will be very gratefully received!

We can use some code to add overlay over video
