This demo uses an image instead of a video - but the set-up is the same… the “Video” and masking element are placed in a group (i.e. “Video” Holder in this example); then set-up the group as needed in the “Flexible Layout” section of the “Metrics Inspector”. In this example the group is pinned on all four sides.
Yes, but it works only if the mask is set to be VISIBLE in content overflow.
This issue will be only happens in wordpress, but works fine in local hype preview mode, so I tried a lots to check the reason, fortunately, it works fine in small width screen, but I am sure it will be out of control if the page is showed on large screen with high resolution since the things behind mask will show up .
For your comparing, I upload the one by Hype plugin with setting the mask to be hidden in content overflow, and it works fine in local, but the video will be align at left in wordpress:
