The page "Header Image" field populates the header background image.  If a header video is present this image will be the preview image while the video is loading and also serves as the fallback for devices that do not support video.

Images should be 2,732px wide by 920px tall.  If the header large checkbox is selected for the page the image is recommended to be 2,732px wide by 1,536px tall.

*NOTE - The link list "Default Header" contains a single link with an image that serves as your header fallback if a page does not contain a header image option.

Using the field "Header Background Video (mp4/h264)" will replace the background image with a background video.  The video must be MP4/H264 formatted video and should have a ratio of 16:9.

*NOTE - This is a looping/muted background video so the video should be kept short in size/length (under 30 seconds).

If a rotator is assigned to a page the images will display as slides.  The title and caption or optional and will display as an overlay.   The button uses the Button Text field.
