rounded corners on all images including custom thumbnails for videos

Hi all!

My CSS rounds the corners on all images but when I use a custom thumbnail for my videos, those don't get rounded.

The code used is:

.sqs-block-video img, .sqs-block-image img {
    border-radius: 10px;
}

Can someone please help, I have absolutely no idea why this happens :(

Can you share link to page where you insert video? We can check easier.

It's on this page, you'll see that all photos have the rounded corners but the very first podcast I've used a custom thumbnail (and will be doing so from now on) and it has sharp/square corners. I just can't understand why.

Try this:

.sqs-video-wrapper, .sqs-video-overlay, .sqs-video-opaque {
    border-radius: 10px;
}
