Hi. @anusky1
?If you are using the video as the slide background video, then it will fit the width of the page, and there will be no margins unless it’s added by the page layout of the theme. But if you are using it as a normal video element, then it will fit the width of the “Content Area” by default and if your page width is bigger than the specified width for the content area then you will have some margins on both sides. I think this is your case.
?If you want to use the video as a video element and also fit it to the full width of the page, you need to select the element, then switch the “Wrapping” option from “Wrap” to “No Wrap”. This way the selected element will go beyond the content area and will consider the edge of the page.
?After that, set the video to the edge of the slide, and you are done.
