Hi everybody,
I am trying to add a video in a project in the CMS collection of Projects, but when I try to add it manually it shows up in every other project. When I add the video in the collection it show as tiny thumbnail when video is played. What I am not getting here?

Thank you

Could you provide more details about which CMS field in your collection you are using and the element on the page you are having a problem with?
