I'm having trouble with YouTube embeds messing up the thumbnails (see below). Is there any way to fix this without changing the aspect ratio of the thumbnail on YouTube? Why does it need to be 4:3?
I hope you are embedding this using the iframe embed code provided by YouTube, If so than you will have option to set explicit Width and Heigh or you can also use CSS properties(e.g object-fit: cover) . Hope this helps
