My site www.clarionstl.com was working perfectly. But if you scroll down to the work section and click on the first video to open it (looks like a book inside of an iPad). The vimeo video thumbnail preview (keyframe) is blurry. It did not used to be this way and this bug appeared without a code change on my end. I have uploaded the video again to correct and the error happens again. I have tried selecting different keyframes and the issue happens again. Oddly I have 2 other vimeo videos using the exact same css and they do not have the issue.
Thanks in advance.
