Hi @charlie,
I have had this problem in the past and I have been seeing a few others on the facebook group having a similar issue so thought it might be worth a native solution.
Using the starter stack, any background video are positioned left 0 top 0. for most use cases a center center approach would be better, but what would be better again would be a positioning input on the video (in the same way that exists for background images)
I have used code like this to force the issue in the past but I think this would make life easier for quite a few people if it was an option on the background layer video (to create a center bottom focus to the video)
$el .x-video .x-video-inner .x-mejs .has-stack-styles {
top: auto !important;
bottom: 0 !important;
left: 0 !important;
right: 0 !important;
}
Thanks in advance!
