Elements Gallery YouTube video thumbnail sizing/aspect ratio

I’ve imported a YouTube playlist into my resources. From a blank elements project I inserted a container, with a gallery inside. I dragged the YouTube playlist folder into the Gallery and it displays all the video thumbnails. I cannot figure out how to show the entire thumbnail(s), they are all cropped. I selected “wide” for the format. BTW, the entire thumbnail shows up in the lightbox. Is there an easy way to format the thumbnails? Here is a screen shot.
